On device, there is an unwanted border line on the SCIChartSurface. Please refer to the screenshot.

I tried removing this by setting the border width and setting it’s colour as white as below
self.surface.view.layer.borderColor = [[UIColor whiteColor]CGColor];
self.surface.view.layer.borderWidth = 2.0f;
However, this does not set the border of the SCIChartSurface.

How do I remove this unwanted border line?

Dear SCICharts support:
We have a very large project that must be migrated to version 3 because right it uses version 2.
I am stuck in the following issues:

1/ I cannot convert Double or Date to ISCIComparable.

Our x axis contains Date-timestamp values and I am trying to find the index of the dataseries.xValues of a specific Date having as parameter my Date value which is Date type and not ISCIComparable.
How can I do this ?

When I try my attempt 1:

let x: Double = <DoubleValue>
let index = dataSeries.xValues.findIndex(of: x, searchMode: .nearest, isSorted: true) 

I am getting the build error: “Cannot convert value of type ‘Date?’ to expected argument type ‘ISCIComparable?'”

When I try my attempt 2:

If I also try to iterate the xValues and find the ISCIComparable value which has doubleValue equal the x then I get the error “Type ‘ISCIList?’ does not conform to protocol ‘Sequence'”
I mean something like this:

let x: Date = Date()
var comparableValue: ISCIComparable? = nil
for val in dataSeries.xValues {
    if val.toDate() == x {
        comparableValue = val
    }
}

So any solution please ?

2/ I am trying to update the last point of dataSeries using this code:

let lastPoint = dataSeries.count - 1
if let open = dataSeries.openValues.value(at: lastPoint) {
        dataSeries.update( open: open,
                                    high: max(dataSeries.highValues().value(at: lastPoint).toDouble(), mbidPrice),
                                    low: min(dataSeries.lowValues().value(at: lastPoint).toDouble(), mbidPrice),
                                    close: mbidPrice,
                                    at: lastPoint)     }

and I get the error “Cannot convert value of type ‘ISCIComparable’ to expected argument type ‘ISCIValues?’ “
Why ? How should I do this ?

Thanks a lot in advance

Hi,

I’m trying to convert Java code to swift and I need the AnnotationLabel’s setAxisLabelStyle equivalent.

AnnotationLabel annotationLabel = new AnnotationLabel(getContext());
annotationLabel.setLabelPlacement(LabelPlacement.Axis);

            annotationLabel.setAxisLabelStyle(new Action1<AnnotationLabel>()
            {
                @Override
                public void execute(AnnotationLabel annotationLabel)
                {
                    annotationLabel.setFontStyle(new FontStyle(37.0f, Color.BLUE));
                    annotationLabel.setBackgroundResource(R.drawable.current_price);
                }
            });

How can i apply this code in swift?

I’m getting the following crash:

2020-02-14 16:45:43.902812-0500 CommonStock Development[2425:710225] -[SCIRolloverModifier onTouchesCancelled:]: unrecognized selector sent to instance 0x282ffe080

whenever I try to scrub my chart, I must also note that in order for the legend to show, I have to tap really hard on the surface.

This is my code:

func set(data set: SimpleChartDataSet, alternate: SimpleChartDataSet) {

    let lineDataSeries = SCIXyDataSeries(xType: .double, yType: .double)
    let dashedDataSeries = SCIXyDataSeries(xType: .double, yType: .double)

    group.enter()

    DispatchQueue.global(qos: .userInteractive).async {
        for (index, i) in set.enumerated() {
            lineDataSeries.append(x: Double(index), y: Double(i))
        }

        for (index, i) in alternate.enumerated() {
            dashedDataSeries.append(x: Double(index), y: Double(i))
        }

        group.leave()

        lineSeries.areaStyle =  SCILinearGradientBrushStyle(start: CGPoint(x: 0, y: 1), end: CGPoint(x: 0, y: 0), start: UIColor.green, end: UIColor.clear)

        let dashedSeries = SCIFastLineRenderableSeries()
        dashedSeries.zeroLineY = set.min() ?? 0.0
        dashedSeries.dataSeries = dashedDataSeries
        dashedSeries.strokeStyle = SCISolidPenStyle(color: UIColor.white, thickness: 2.0, strokeDashArray: [2.0,2.0,2.0,2.0])

        SCIUpdateSuspender.usingWith(self.surface) {

            self.surface.xAxes.clear()
            self.surface.yAxes.clear()

            let xAxis = SCINumericAxis()
            xAxis.drawLabels = false
            xAxis.drawMajorBands = false
            xAxis.drawMajorGridLines = false
            xAxis.drawMinorGridLines = false
            xAxis.drawMinorTicks = false
            xAxis.drawMajorTicks = false
            xAxis.drawLabels = false

            let yAxis = SCINumericAxis()
            yAxis.drawLabels = false
            yAxis.drawMajorBands = false
            yAxis.drawMajorGridLines = false
            yAxis.drawMinorGridLines = false
            yAxis.drawMinorTicks = false
            yAxis.drawMajorTicks = false
            yAxis.drawLabels = false

            self.surface.xAxes.add(items: xAxis)
            self.surface.yAxes.add(items: yAxis)
            self.surface.renderableSeries.add(items: lineSeries, dashedSeries )
            self.surface.chartModifiers.add(SCIRolloverModifier())
        }
    }
}

If we set ClipMode.None we can pan infinitely to the uncharted space of left and right. this is fine.
But I want to do panning infinitely only to the left side. So I set ‘clipAtMax’. This is stop panning at right. But instead of panning infinity to the left, it is stretching the left part.
Any solution ?

worked.

I always get the message “Sorry! Your license token appears to be invalid. etc.”
What’s the right way?

Hi , many of the charts provide a way to set the date on the x axis for the data series and that makes the axis match the DataSeries value defined for that axis, but for heatmap dataseries when you define xType as date the xAxis of type date is not displaying on surface, I don’t know what I’m doing wrong and there is no sample for dates on GitHub , the samples only use int , would be great if you can provide a date sample for the heatmap , thanks

Hi,

I am using SciChart_iOS_SDK_3.0.0.5074 with Swift 5.

I want to show string type on X-axis. I am using below code snippet.

class YearsLabelProvider: SCILabelProviderBase<SCINumericAxis> {

   var xLabels: [String] = ["Test", "Test", "Test", "Test", "Test", "Test", "Test", "Test",     "Test", "Test", "Test", "Test", "Test", "Test"]

   func update(_ axis: ISCIAxisCore!) { }

   override func formatLabel(_ dataValue: ISCIComparable!) -> ISCIString! {
        let index = Int(dataValue.toDouble())
        return NSString(string: index >= 0 && index < xLabels.count ? xLabels[index] : "")
    }

    override func formatCursorLabel(_ dataValue: ISCIComparable!) -> ISCIString! {
        let index = Int(dataValue.toDouble())

        var result: String?

        if (index >= 0 && index < xLabels.count) {
            result = xLabels[index]
        }
        return NSString(string: result!)
    }
}

Application crashes while loading with the following error –

” *** Terminating app due to uncaught exception ‘Initializer not allowed Exception’, reason: ‘Parameterless initializer of Chart.YearsLabelProvider class shouldn’t be used. Please use one of the designated initializers instead'”

Kindly help us resolving this issue since this is a showstopper issue.
I would also like to know about what data SCIXyDataSeries accepts when we are working with strings.

I am considering applying server-side licensing for my javerScript application.

In the document below, there is a phrase “Our server-side licensing component is written in C++.”
(https://support.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)

However, there is only asp.net sample code on the provided github.
(https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Sandbox/demo-dotnet-server-licensing)

I wonder if there is a sample code implemented in C++ for server-side licensing.

Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?

Hello,

I would like to add a corner radius (to give rounded corners) to the SciChart rollover tooltip in iOS. I saw that there is a “tooltipCornerRadius” property in “SCITooltipModifierStyleProtocol”, but I am having trouble figuring out how to use this. Can someone point me in the right direction?

Thank you.

Hello

In the real-time line chart, I want an animation like the video(link below).
Can you be provided with animations such as a point where a point drawn in real time continues to blink?

Hi!

I tried implementing pinch zooming for real time chart in the demo project(FIFO Performance Demo and ECG Monitor Demo) and found that it’s not possible.

I used the following code:

self.surface = [[SCIChartSurface alloc] initWithView: self.sciChartSurfaceView];
SCIPinchZoomModifier * pzm = [[SCIPinchZoomModifier alloc] init];
[pzm setModifierName:@”PinchZoom Modifier”];
self.surface.chartModifier = pzm;

If it is so, then how can I achieve it ?

Could I have a date please.

is it possible for the December or more likely for January?

Hello, I’m trailing your library right now. I would like to be able to move the graph around as well as a cursor on the graph. So I enabled both SCIZoomPanModifier and SCICursorModifier. But since both use one finger panning, the result wasn’t that good. Do you have any guidance for solving the conflict and letting them working together? I’m thinking to do it in the following way: if the touch location is within certain pixel range of the cursor, panning action will move the cursor, otherwise it moves the graph. Is it possible? Thanks

I’m using Xamarin.iOS and the SciChart.iOS NuGet. When adding a LabelProvider to an axis the iPhoneSimulator with iOS 13.2 crashes without warning or exception back to the phone menu. This issue is not present on Android using the same API usage pattern.

This effect is not just in my own apps but can be replicated by running the latest Examples app on the same simulator. Examples which demonstrate the same behaviour include “Custom Theme”, Stacked Column Side by Side Chart”, “Using Theme Manager”, all of which set the LabelProvider in the source code.

Is this a known bug? Maybe an incompatibility with the latest version of Xamarin.iOS.

I noticed that this issue has been reported before.

This is a deal breaker for us at the moment as formatting axis labels is pretty crucial.

Guys can you tell me please why I get this error after build on new `mac M1 chip and how to solve it:

error: unable to load standard library for target ‘arm64-apple-ios8.0’

Hello,

I would like to be able to change the rollover tooltip cursor color. It seems to be defaulted to the lineseries areastyle property color. I would like to be able to change it to a different color. I have not been able to find anything in the docs regarding how to do this.

Thank you

Hi,
we are using an UICollectionView to display different kinds of views in our application, including charts created with SciChart. We noted that every time a cell with a SciChart is loaded, some memory is allocated and not freed when the cell disappears, which leads to a massive memory leak and eventually crashes the application.
Is there a way to free SciChart resources on demand? Or maybe you suggest another solution to solve this issue?
Regards,
Anna

I’m trying to add annotations on a chart but they are rendering above my legend.

Initially (similar to most of the demo code I’ve seen), I setup my modifiers, then created my series and animated them in — then added my annotations (adding to annotationGroup). This created a timeline of blank chart surface with legend (good so far), annotations popping in before the chart series animated in (weird / not good) and on TOP of the legend (really bad), then the animation of the series after that.

I’ve tried about everything I can think of and the best I’ve been able to do is use a completion block of the animation rendering the series — and moved my chart modifiers (and legend) into that completion block. If I put the annotations in the completion block, they will render after the chart modifier and I have the same problem (even if placed after the chart modifiers). I have to set the annotations before the animation, and then the chart modifier in the completion block will work and the legend will be above the . Of course, this is a bit odd too — as first my annotations pop up by themselves on the blank surface, followed by my series animating in, then at the end of the 2 second animation, the legend just pops in.

I really would like my legend to be rendered first on the blank surface and the annotations and chart series to animate in together under my legend. I’m gathering that’s unlikely (at least the animation part) — but is there anyway I can place my legend first and still have the annotations go under it? It feels like the layers should be: modifiers > annotations > rendered series. I also I’ve read this order before in some WPF docs I believe, but doesn’t seem to be respected on iOS?

UPDATE: My current work around isn’t sufficient because I really need access to the renderable series to create the annotations which means I really can’t defer my chart modifiers (i.e. legend) until after the annotations. Additionally, if I need to update (remove / re-add) an annotation due to a series being deactivated in the legend, now my annotations are on top of the legend again.

I’ve received this crash report for a long time since I use this SDK.
But now it’s the largest amount of crash report in the newest version.
Do you have any idea about this?
I use the SDK to show meter temperature and humidity data. It’s about 10k to 30k data show in the chart and every time the user has download the data or the user zoom, drag the chart will recalculate the min, max, avg number in the visible time range.
Thank you~

Hi guys,

I just started using SCICHART. I am working my way through the provided tutorials and i noticed that when i add a SCITooltipModifier to the chart, all my other modifiers (zoom and pan and pinchzoom) stopped working. Is this normal? Because i want my chart to have zoom functions and show what datapoints are touched by a user.

Thanks in advance!

Hi,

I’m trying to limit the x-axis panning up to an annotation that I’ve drawn on the graph. This annotation can be beyond the current data’s position (i.e. data’s timestamp is at 5/4/2017 11:00:00, annotation’s position is at 5/4/2017 16:00:00). Is there a method, or any way that I can use to limit the x-axis panning up to the annotation’s position instead of limiting it to the data series’ max X?

Regards.

Hi everyone,

I have a scroll view containing (among others) subviews with SciChart surfaces. I use this method:

 [self.scrollView.layer renderInContext:UIGraphicsGetCurrentContext()];

… to take a screenshot of the whole scroll view (render it as a UIImage). All charts are rendered as black rectangles. Same thing happens if I use “Capture view hierarchy” in XCode – black rectangles where there should be a chart.

Any ideas?

Hello,

I am trying to round the corners of the bars produced by a SCIFastImpulseRenderableSeries (pointMarker is hidden). Any suggestions how to do that?

Thanks!

Hello, I’ve been trying to setup an Ellispe Point Marker graph which shows a linear regression line within the graph, I’ve copied the demo code into another project and it seems to show Ellispe Point Markers, but when I try it out using another project, it doesn’t seem to show up. The issue is that the graph shows up, along with the axis and the linear regression lines, but the Ellispe point markers don’t show up.

When I run the code, the linear regression line changes from new data that is being pushed, but the Ellispe pointer markers don’t show which I’m assuming means that the data is being pushed through/into the chart, but the point markers are specially not showing up for some reason. I’m wondering if anyone can help me regarding this situation, and I’ve looked through the code several times and I can’t seem to find what is causing my point markers to not show.

Unfortunately I can’t completely share the project due to confidentiality reason within my workplace, therefore I shared some screenshots which outline the code that is being used to for the SciChart Graph.

Any help would be greatly appreciated, and if there are any more questions regarding this issue, please let me know and I’ll try my best to answer them and provide more information. Thank you.

I have a Xamarin forms Project with one page of my app containing a SciChart. On that page, I have a RelativeLayout.

In the code behind for that page, I pass my layout to a dependency service method which adds the SciChartSurface to it depending on the platform. This has tested well on various Android platforms.

For iOS, I’ve tested on a device running iOS 9 and simulators running 9, 10, and 11. And any run less than 11 does not display. The view is simply blank.

Here’s the code where I add the SciChartSurface to the view.. I’m still new to SciChart, so I’m not sure if I’m doing everything totally correct.

public void renderSciChart(Xamarin.Forms.RelativeLayout masterLayout, Xamarin.Forms.RelativeLayout topLayout)
    {


        SciChart.iOS.Charting.SCIChartSurface Surface = new SciChart.iOS.Charting.SCIChartSurface();
        Surface.TranslatesAutoresizingMaskIntoConstraints = true;
        SciChart.iOS.Charting.XyDataSeries<double, double> dataSeries = new SciChart.iOS.Charting.XyDataSeries<double, double>();
        //generateDataPoints(dataSeries);
        var xAxis = new SciChart.iOS.Charting.SCINumericAxis{/*GrowBy = new SciChart.iOS.Charting.SCIDoubleRange(0.1, 0.1), VisibleRange = new SciChart.iOS.Charting.SCIDoubleRange(1.1,2.7)*/};
        var yAxis = new SciChart.iOS.Charting.SCINumericAxis();
        var renderableSeries = new SciChart.iOS.Charting.SCIFastLineRenderableSeries { DataSeries = dataSeries, StrokeStyle = new SciChart.iOS.Charting.SCISolidPenStyle(0xFF279B27, 2f) };
        using (Surface.SuspendUpdates())
        {
            Surface.XAxes.Add(xAxis);
            Surface.YAxes.Add(yAxis);
            Surface.RenderableSeries.Add(renderableSeries);
            Surface.ChartModifiers = new SciChart.iOS.Charting.SCIChartModifierCollection
            {
                new SciChart.iOS.Charting.SCIZoomPanModifier(),
                new SciChart.iOS.Charting.SCIPinchZoomModifier(),
                new SciChart.iOS.Charting.SCIZoomExtentsModifier(),
            };
        }

        masterLayout.Children.Add(Surface.ToView(),
        widthConstraint: Constraint.RelativeToParent(parent => parent.Width),
        heightConstraint: Constraint.RelativeToParent(parent => parent.Height * 0.5),
        yConstraint: Constraint.RelativeToView(topLayout, (RelativeLayout, element) => element.Height));
    }

Additionally, here’s a Screenshot of the same code running on a simulator with iOS 10 (Left) and iOS 11 (Right).

Hello,

I am using SCI line chart for Android and iOS. How I can I add Multiple scales on the same graph for different lines?

Please do the needful.

Hello,

We have an app where we need to specify a different width for each column. I have attached an image of the result we want. We are currently using “SCIFastColumnRenderableSeries” for the diagram, but all columns have a fixed width and I couldn’t find any way to modify it.

Do you have any suggestions how to accomplish this?

Thanks!

Good day! I have download this zip archive SciChart_iOS_SDK_4.2.0.5533.zip, on my laptop. Opened it and can not find the file SciChart.xcframework, according description from this article. I need to add library to Xcode frameworks, but I can not do it. Please can you tell me where can I get this file.

Hi,

I have a very simple iOS project in XCode 13 which uses Swift. The project has a tab bar controller with two tabs. The first tab brings up a sample home screen and the second tab initializes a blank SciChart graph.

I want to eventually be able to sometimes change what data is shown on the graph (via Bluetooth), and therefore I want to run my graph code every time the tab for the graph is selected. I put all my code for SciChart inside:

override func viewWillAppear(_ animated: Bool)

and this almost works fine, but declaring

let surface = SCIChartSurface() inside of override func viewWillAppear(_ animated: Bool)

seems to be causing some sort of memory leak. Switching between tabs often causes my app to crash and XCode reports the following error message: “Terminated due to memory issue”

Is there a better way to initialize my graph to prevent this memory leak? Or is there way to flush the “surface” variable from memory when transitioning between tabs to prevent this memory issue from occurring?

My small sample project is available here which demonstrates the memory leak when switching between the home screen tab and graph tab: https://drive.google.com/file/d/1mz88R3kKvoPqSGxFzohoHGDkseSwgHPh/view?usp=sharing

Any help greatly appreciated, thanks!

Hi, guys

I’m interesting in alignment for line at SCIAxisMarkerAnnotation. For example for top, middle and bottom position. Like at alignment_to_top.png. So is there some possibility for this?

UDP: Is there possibility to hide annotation from chart view?
Something like setHidden: for UIView.

I was able to add multiple y axis and able to fill data on different y axis but the problem is all the y axis are overlapping. What I want is how can I segregate y axes in such a way that they should appear one below the other in the same surface. I tried adding two different surface but then I am not able to add single cursorModifier to both surface. Our android developers had used something called YAxisStackedLayoutStrategy to achieeeve this is there any equivalent class for iOS

Hi

I have a SCIFastLineRenderableSeries backed by data in SCIXyDataSeries.

I setup FIFO to 300 (this just a number I may increase, but it stores 30+ seconds of data)

x data is time stamp.

each time I have new data, I set a new visibleRange to show about 30 seconds of data on screen

xAxis.visibleRange = [[SCIDoubleRange alloc] initWithMin:SCIGeneric(secondSinceStart-31) Max:SCIGeneric(secondSinceStart)];

So this will scroll along showing latest 30 seconds of data. And that’s great.

But I want to scroll to the left to view the older data. because of the visibleRange is set I am not able to touch the axis labels and do anything)

how do I set the visibleRange or maybe not set it, so I can enable the scroll.

Here is the drag modifier I use , but I think it does not do anything either because of the visibleRange
SCIXAxisDragModifier * xAxisDragmodifier = [SCIXAxisDragModifier new];
xAxisDragmodifier.dragMode = SCIAxisDragMode_Pan;
xAxisDragmodifier.clipModeX = SCIClipMode_None;

Thanks
