Questions

I was able to develop and run everything using the scichart alpha build from Jun 11th.
This includes SciChart2D, SciChart3D, with a minor error.
I was using .NET Core 3.0 Preview 6+, Visual Studio 16.3 Preview on a Win7 box.

However, the client wants to upgrade to Windows 10.
So I installed Visual Studio 16.3 (2019), and .NET Core 3.0 and I was able to build all the packages etc.

However, when launching the WPF part of the application, I was at first encountering AccessViolation exceptions in CreateRenderTarget().

I removed all my SharpDX components, and tried again. I was able to get around this problem by using a version of SciChart 6.0 greater than the Jun 11th alpha version – v. 6.0.0.12382-alpha.

I can now load SciChart2D package.

However, SciChart3D is now throwing null reference exceptions when loading. I’ve included the screenshot. This occurs even with the 6.0.0-beta version.

Please advise.

Hello Team,

We are going through the Trial version of Sci Chart and we are specifically interested in 2D Scatter Chart and Simple Scatter Chart 3D.

For 2D Chart we tried to bind up-to 1 Million data points and it worked perfectly and we can zoom in 2D Scatter Chart to view each and every point.

When we tried the same for Simple Scatter Chart 3D, it was competitively slower than 2D Chart.

can we do the same in Simple Scatter Chart 3D?

Currently the whole chart is zooming in. Is there a way so that user can zoom in (XAxis , YAxis ,ZAxis ) individually so that each and every point in the chart can be View-able ?

Thanks,

I would like to create custom annotation combined with multiple annotations like attached picture.(Text + box + line * 3)

Are there any good solutions?

Now I am creating it with separate each annotations showed code below. In this way, it is difficlt to move or delete them with group.

        <s:SciChartSurface.Annotations>
            <s:TextAnnotation Foreground="Black" 
                              HorizontalAnchorPoint="Center"
                              VerticalAnchorPoint="Bottom"
                              Text="XXX um" 
                              X1="90" 
                              Y1="6" />
            <s:BoxAnnotation X1="84" X2="96" Y1="2" Y2="11" Background="#77FFFFFF" />

            <s:LineAnnotation Stroke="Black" X1="85" X2="95" Y1="3" Y2="3"/>
            <s:LineAnnotation Stroke="Black" X1="85" X2="85" Y1="6" Y2="3"/>
            <s:LineAnnotation Stroke="Black" X1="95" X2="95" Y1="6" Y2="3"/>
        </s:SciChartSurface.Annotations> 

And one more question.

How to catch the event of adding annotation of view side from viewmodel?

Thank you.

hello

I have two questions,

First , when I using :

   sciChart.ExportToFile(SaveFileName, Core.ExportType.Jpeg, false,savingImageSize);  

In ContoursView ,this function works well, however in UniformMesh3DChart and SurfaceMeshContours it dosent work.
Only these parameters can be used:

    sciChart.ExportToFile(SaveFileName, Core.ExportType.Jpeg, false);  

as these parameters they dont work either:

    sciChart.ExportToFile(SaveFileName, Core.ExportType.Jpeg, true);  

Second, As “ExporToFile()” function, Can I export to file with ColorMap in UniformMesh3DChart and SurfaceMeshContours ?

In many of our applications we will have a number of flags that need to get plotted with data, these are usually each just represented by a single bit in a 32 bit integer.

Would it be possible to write a custom render-able series that plots a trace for each bit, or alternately would it be possible to point multiple custom renderable series at an XyDataSeries and have each of them plot a single bit.

I have started to have a look into this but am not sure how much of the re-sampling process happens before draw, and if this would make this a pointless exercise.

In addition, how much performance is lost by creating custom renderable series (vs using a number of the FastLineRenderableSeries on a dx surface)

Is dashed line is available in Scichart Android?

Hello!

I am trying to render a HeatMap and align labels next to squares (see the attached image). However, I am running into two issues.

Firstly, I am using RenderTransform to shift labels so that they are aligned with the squares instead of being on the borders between them. It works, but does not look good as I resize the control.

Second, the axes render the last label outside the view. I tried setting VisualRange and VisualRangeLimit but it did not help. It hides the last data column (or row) and still displays the last label.

Any suggestions on how I can solve it?

I am attaching a sample project.

Thank you in advance!

I need to know if the user is dragging the entire line annotation or just dragging one end.
If the user is dragging the entire line, I see this cursor:

If the user is dragging just one end, I see the hand cursor:

How can I detect this from the code behind?

I have looked at all of the properties and commands.

Thanks,

Hi!

I would like to plot a series as a solid line AND include error bars. The way I do this now is to define a single series:

var fSeries    = new HlcDataSeries<double, double>();
fSeries.SeriesName = $"My Series!";

And then two different ViewModels:

var fLineVm = new LineRenderableSeriesViewModel();
var fErrorVm = new ErrorBarsRenderableSeriesViewModel();

And set the data series to belong to both:

fLineVm.DataSeries = fSeries;
fErrorVm.DataSeries = fSeries;

This looks ok. But when I show the legend, I see “My Series” in the legend twice, and I can control the error bars separately from the line series.

What I want to happen is that I see the series a single time in the legend and if I turn it off (uncheck it) everything disappears.

Right now, i’m adding those two ViewModels to an ObservableCollection of IRenderableSeriesViewModels and then SeriesBinding to display them.

I’m looking for a way to use the mouse wheel to adjust the range on whatever Y-Axis (NumericAxisViewModel) my mouse is over and came across a HasYAxisDragModifierIncludeAxis property.

I’ve set it to True and False and I don’t notice a difference on the axis.

I am doing all of my integration with SciChart using c# code.
Is there a way to simply customize the text of the Rollover modifier?

By default it shows

“`
x: somevalue
y: somevalue
z: somevalue

“`

when a data point is selected. I would like to simply change it to

“`

Time: somevalue
Profit: somevalue

“`
Is there a way to do this in pure c# without having to define xml templates etc?

Hi,

I am using VerticalLineAnnotation to point to a specific value of XAxis. I want to move this annotation by binding this X1 property and the SelectedX property of ViewModel. But even if SelectedX property was changed, the location of this annotation was not changed immediately. It was changed only after operating the chart (Zooming, etc).
Please let me know any solution to move an annotation immediately.

Thanks,

Hello.

I am working on Xamarin Android project with C#. Since having a legend within the chart causes problems with too many axis’ (no scrolling is available thus selecting different series in a legend becomes unavailable) and having a legend outside of chart area, anywhere we desire, would be of a preference, is there a tutorial on how could I achieve such a thing? Our project needs this functionality for both Android and iOS.

Would be grateful if anyone could help out with this issue.

Thank you in advance!

Hi…..
I could be able to set clip mode for X axis in ZoomPanModifier(), In the same way I would like to set clip mode Y axis but I couldn’t.
Is there is a way to do that?

Hi,

I have a simple digit chart with four possible values (0, 1, 2, 4).
I want to show all values on Y axis label, but it only shows 0 and 2, is there any solution?

Dear scichart support.

I’d like to make the two map (Heat map and bubble chart) mixed like attached picture.

Is it possible?

and also I’d like to confirm that it is possible to bind heatmap with observableCollection.

When putting a chart into a listbox, the listbox doesn’t detect if the chart is clicked.

How can i change this, or there is any workarround to it? because i need it to select the parent ListBoxItem.

The problem is that when you put an event listener on the chart it doesn’t know where it is in the list, and when you put it in the listbox it doesn’t see it at all.

Thanks.

PS: I attached an example project where this happens.

hello, i use RolloverModifier on my chart, can i hide Pointmarker?

Hi,,
I am using RubberBandXyZoomModifier modifier to zoom the rectangular area of plot. It works fine when rectangle area is within the bound area of plot. But when rectangle area is goes out side the surface , zoom doesn’t happen
Please let me know any solution to zoom in this scenario.

Thanks

Hi!

I have a chart that display time-series data and sometimes I have a few minutes of data, other times I have hours. All of the data points are taken every minutes. The X-Axis starts at 0 minutes and progresses from there.

My goal is to have the Axis Title say “Minutes” if there are < 120 points of data. If there are > 120 points of data then I want the Axis to be titled “Hours” and then divide the X-Axis label by 60.

I’ve started with this: https://www.scichart.com/documentation/v5.x/webframe.html#Axis%20Labels%20-%20LabelProvider%20API.html

and it’s doing about what I expect. I check the AxisCore’s Range and if the range is > 120 I set the AxisCore.AxisTitle to “Hours”, otherwise “Minutes”. So far so good.

The problem is that doing it this way means I have labels such as “48.333333” for the hours.

If, on the other hand, when I create the XYSeries that I’m plotting I pass in the already-divided-by-60 values, SciChart seems to select whole numbers so instead of showing me something like “48.333333” it would either show me “48” or it would use 50 or another whole number for the tick marks.

So my question: Is this doable by just writing a custom LabelProvider? Do I need to write a custom Axis class instead? Or somehow tell the Axis that’s in-use to recalibrate itself by dividing all of the elements by 60 before computing tick marks?

In the images I’m attaching, one plot shows me plotting a series where when I create series the x-value is being divided by 60 before I call .Append() on the series. The other one shows what happens when I use my custom LabelProvider and divide by 60 when the Axis label is drawn.

Thanks!

I am still experiencing the effects of this defect despite using v2.5.0.2598 of the Android libraries. Can someone please explain to me how to circumvent this behavior? It seems silly to require a base series that is ultimately going to be replaced by real-time updates.

Cheers

When I import my own .jar library after importing Scichart .aar libraries(core and data) my own .jar library generates an error(Error: findLibrary returned null). How can I overcome that error.

I’m trying to control the size of the bubbles that are being plotted in the FastBubbleRenderableSeries.

I’ve tried all these things, but I can’t seem to figure it out:

1. Changing values that are plotted: there seems to be some “normalization” that occurs behind-the-scenes, so whether I scale the raw values, the bubble size is identical.
2. Changing ZScaleFactor: Regardless of what value I use for ZScaleFactor, the bubble size is still the same.

I’ve attached the problem I’m facing, would appreciate your help.

Thanks.

Hello,

I have the problem, that sometimes only one label is shown on the X-Axis even when there is space to show some more, than only one.
The property “IsLabelCullingEnabled” would show them all, but than it is ugly if there is not enough space.
So what can I do to have some more Labels shown?

In the Screenshots you can see that with only a few pixels more, more labels are shown, but the could have been also shown with less pixels (Especially Label “1” and “22” could have been shown).

I’m working on a project that updates about 100,000 pointers in real time, but it takes too much time to change the individual colors of the pointers.
Is there any quick way to change pointer individual color?

Hello,

I have created some ChartModifiers in a ModifierGroup in my ViewModel class (using Caliburn.Micro as MVVM framework, not code behind) and bound the group to my SciChartSurface in xaml. Now I want to apply some styles to my modfiers in xaml. Just creating styles with the specific target types don’t work so how do I do this?

Hello

I have 2 charts, a 2D Heatmap and a 3D Waterfall chart, and I want to be able to programmatically change their color palettes.

The 2D heatmap is set up like this, with the GradientStops bound to an ObservableCollection:

...
<s:HeatmapColorPalette x:Key="HeatmapColorPalette" Maximum="{Binding MaxValue,Mode=TwoWay}"  GradientStops="{Binding ColorPalette}"/>
...
<s:SciChartSurface.RenderableSeries>
    <s:FastUniformHeatmapRenderableSeries 
        x:Name="heatmapSeries" 
        DataSeries="{Binding Data}"
        ColorMap="{StaticResource HeatmapColorPalette}">
    </s:FastUniformHeatmapRenderableSeries>
 </s:SciChartSurface.RenderableSeries>
...

This works as expected. When the binding changes the palette/heatmap changes.

The 3D waterfall is set up the similarly:

...
<s3D:GradientColorPalette x:Key="GradientColorPalette" IsStepped="False"  GradientStops="{Binding ColorPalette}" />
...
<s3D:SciChart3DSurface.RenderableSeries>
    <s3D:WaterfallRenderableSeries3D
        x:Name="waterfallSeries"
        DataSeries="{Binding Data3D}"
        YColorMapping="{StaticResource GradientColorPalette}"
        SliceThickness="1">
    </s3D:WaterfallRenderableSeries3D>
</s3D:SciChart3DSurface.RenderableSeries>
...

This, when passed the same data, doesn’t render the chart.
This chart otherwise works fine if I define the GradientStops statically in the XAML.

This is the GradientStops definition (in f#):

let BlueRed = 
        new ObservableCollection<GradientStop>([
            new GradientStop(Color.FromRgb(0x00uy,0x00uy,0xFFuy),0.0)
            new GradientStop(Color.FromRgb(0xFFuy,0x00uy,0x00uy),1.0)
        ])

I am not sure what I am missing.

(edit: apologies for formatting issues in the question)

Hi,
I am working on Scichart android appliication.By default it is appending infinite Yvalues which are randomly generated one by one. I want to append finite data in AnimatingLineChartFragment() but it will not accept it, like when I append arrayList of yValue it will generate an error and ask to add Collections.singleton(t) on 1st argument .Afterwards when I run the programme it works fine but when Fifo Capacity ends it starts to draw last line again and again. Plz help me that how can Animate Lines on my data?

Why Scichart for Android Tutorial 09 – Linking Multiple Charts is not working properly?

Hi,

I’m looking for the old version 3.1.0.5122. Where can I find it?

Best regards

I am working on Scichart Android application .I am using two Scichart surfaces on a single activity ,I want to handle click event on scichart surface so that,whenever I click on surface it will start a new activity which contains a single Scichart.

Dear support,

What is the best way to anchor a GroupBox to the top right corner of a SciChartSurface (as shown in the attached screenshot)? At the moment, I am using an absolute positioning that often fails at initialization or when the surface is resized. I am looking into the annotation API, but have not yet found a clean solution.

Thank you,
Lucas

I am developing an Android application for ELD. I have also explored the graph options SciChart is offering but I could not see a very similar graph to the image I have attached.
Please help me in choosing an appropriate type graph. It would be more helpful if you could name type of the graph I have attached.

I have a fairly simple multiple series line chart, which shows the history of a couple of variables within the last 5, 15, or 30 minutes.

The x axis is always ranged between Now – X mins and Now + 10 secs (to allow for clock error).

I’d like to have the x axis constantly scrolling, smoothly. I’ve not been able to achieve this using a timer. I’ve tried to use AnimatedVisibleRange, triggered from a 500ms timer, but there’s quite visible jerking.

I should add that the data comes in sporadically, but the chart should still scroll without any new data.

What am I missing? Thanks

Hi!

I’ve put a couple of charts in a recyclerview based on this example. I’m using a custome theme that’s basically just a white background and grey gridlines. When the charts get recycled (after scrolling them out of view and then back) they start to look weird. Does anyone know what is causing this behavior? I’ve tried two different versions of SciChart, screenshots attached below. Additionally I used to only get some random black squares like this in version 2.0.0.1654, but I can’t seem to reproduce that now.

Chart normally:

After recycle in version 2.0.0.1654:

After recycle in version 2.5.0.2540:

I have created a CustomControl that have scichart surface which draws a FastLineRenderableSeries and some other controls like buttons etc for controlling how data is displayed.
I have some dependecy properties like
– VisibleRange
– Horizontal and vertical Anotations values
as well as the XyDataSeries<double,double>

When I use the control in a window I can data bind to a viewmodel and VisibleRange and the annotations are fine but not the update of the XyDataSeries.

Any ideas?
