Hello,
I’m trying to convert Android (Java) code to iOS (Swift), and I need to create a custom SCIZoomPanModifier. In the android code, onFling, onDown, and onDown were overridden, but I can’t seem to do that in iOS. How can I override onFling, onDown, and onUp in iOS to mimic the android code?

Thanks

Hello!

I am building an iOS framework that sits on top of SciChart for app developers within our company. I’d like to provide my own default SCIThemeColorProvider object for charts in my framework. Easiest way to do that is to include my own theme plist in my framework’s bundle, but I cannot currently do that (as of 2.0.0.1643) because the SCIThemeColorProvider initializer assumes it’s either in the “Charting.SciChart” bundle or the main bundle.

I’d like to propose modifying SCIThemeColorProvider to add another initializer that takes a bundle ID, like this:

/**
 * Creates theme provider based on specified style
 *
 * @param themeKey The key of style which should be used as base for this theme provider
 *
 * @param bundleIdentifier The identifier of the bundle containing the theme plist identified by 
 *                         themeKey; if nil, the main bundle is used.
 */
- (nullable instancetype)initWithThemeKey:(nonnull NSString*)themeKey bundleIdentifier:(nullable NSString*)bundleIdentifier;

The existing -initWithThemeKey: initializer would call through to this initializer with a nil bundle ID.

I have attached a patch file with this proposed change. Could this be added to an upcoming build?

So I want to draw multiple charts so is there any way I can have stacked yAxes like yAxis 2 should be drawn below yAxis1. I have gone through your example and there I got that we can add multiple surface but its becoming difficult for us to show a crosshair on all surfaces since we have a custom cross hair. Can you guide on same. Thanks in advance

Hi,

I’m attempting to plot on a mountain graph with a DateTimeAxis for the x-axis and I noticed that the plotted time is inaccurate.

The data that am attempting to put in has the following NSDate value: 2017-01-06T10:09:25+0000
Correct me if am wrong, but I believe the time on the axis that ought to be displayed should follow the device’s system timezone? In my case, it is +0800, setting the time to be about 6:09:25 pm

However, the plotted time ends up showing the point to be plotted at 2:09:25 instead.

I’ve tested with a date formatter and it displays the time as it should (6:09:25 pm).
I don’t think I configured anything regarding the axis’s time format, and the insertion of data was done as below:

[self.mountainSeries appendX:SCIGeneric(m.timestamp) Y:SCIGeneric(m.mid)];
[self.chartSurface invalidateElement];

Also, to add on, if I were to extract the XMax value from the axis (in this case, is the timestamp as above), it returns me as such: 2017-01-06 18:09:25 +0000

Thank you.

After upgraded SciChart to SciChart_iOS_SDK_3.0.0.5074, using rollover modifier on a SciChart surface which was embedded into a scroll view will crash the app. It crashed when user scroll horizontally on a SciChart surface inside a horizontal scrollable scrollview. It is the same with the vertically scrollable scrollview.

Hi, guys

My X axis is SCICategoryDateTimeAxis type.

And i have a huge amount of data to display. So i need to display it by scrolling of the chart surface.
So what is the best practice to update data series on the fly and display it at the chart surface?

Hi all,

Why the API’s for iOS, Android and WPF are not identically?
I have seen many samples on the forum, but to adapt it to a different platform is very hard.
A lot of classes are different for each platform.

  • Is there any “comparison” for the different platforms?
  • Is this planned to unify the API’s?

Urs

Hi,

I’d like to update the iOS version to the latest stable one (4.1.0), but after following the steps here: https://www.scichart.com/documentation/ios/current/integrating-scichart-libraries.html
Xcode keeps complaining:

framework not found SciChart.xcframework
clang: error: linker command failed with exit code 1

If I downgrade back to 3.1.1 everything works again. Any idea why the version 4.1.0 is not working? I’m using Pods to manage all dependencies.

Hi, guys

I’m very sad because of you.

On my chart i’m added SCIZoomPanModifier with clip mode SCIClipMode_ClipAtExtents. And it well worked before i have updated lib to ‘2.0.1.1748’. Now it’s works the same way as SCIClipMode_StretchAtExtents. But i don’t want to zoom by scrolling at the edge of data.

Can you look at it and fix as soon as possible?

I had recently integrated SciChart into my app, and faced some problems with chat appearance on trial mode which are described here: https://www.scichart.com/questions/ios/issue-with-scichart-on-ios-simulator
Due to this problems I tried to run my app on an actual device, and got this build error from Xcode:

Hey all,

is there a way on iOS to export a SciChartSurface to a vector format in order to embed the exported chart into a PDF document? Right now the only thing I can find in the Documentation is exportToUIImage(). If not – any ideas for a workaround until such feature is implemented?

Hi, guys

My axis is SCICategoryDateTimeAxis type. And using SCIZoomPanModifier (SCIClipMode_ClipAtExtents) to scroll chart

I’m using setVisibleRangeLimit: method to clip the axis during ZoomExtents

Until v. 2.0.0.1511 it’s work like a charm. But now something had have broken. And it’s doesn’t allow me to scroll chart at right way. It show me all of the data range on chart or only left side.

So can you fix it?

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.

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

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!

I’m having difficulty determining the easiest method of placing the legend outside of the chart surface in iOS. I’ve done a ton of trial and error and have run into several issues. I understand that the SCIChartLegend class is just a subclass of UICollectionView. The problem seems to be these two things:

— When adding a legend via SCILegendModifier it only allows for custom placement if using SCILegendModifier’s initializer which also requires you assign an SCILegendDataSource. Or at least that’s required for the initializer with the useAutoPlacement parameter that I can then set to false (not even sure if that would work once I got that far).

— Placing the SCIChartLegend view manually without first initializing an SCILegendModifier with it results in none of the legend cells being loaded. I would imagine this is due to a missing SCILegendDataSource.

It seems like these could be overcome if I could somehow construct a default instance of SCILegendDataSource. Unfortunately, SCILegendDataSource only exposes one initializer which requires I pass it a xib name for the legend items. But I do not want to customize the legend items- I simply want to be able to construct the default SCILegendDataSource because that is apparently required to get the SCIChartLegend working.

Am I making this more complicated than it needs to be? What’s the simplest path to placing the chart legend where I want in iOS?

Can SciChart be used in UITableviewCell? Is it possible to use Software rendering on iOS?

The OpenGL/Metal charts are great, but I suspect Software rendering would be a better for displaying data in UITableViewCells. There are many mobile apps out there that use charts in tableviews and I’d love to be able to use SciChart here too.

When I embed my view controller in a navigation controller the top of the chart is hidden behind the navigation bar. So I went to the storyboard and found the view controller attributes section called “extend edges” and turned off the option called “under top bars”. This fixes the top of the chart. Now the bottom of the chart drops off the bottom of the screen. The x-axis is completely missing. Does SciChart support this case?

The numeric axis in our app weirdly displays the range from -2000 until 8000, even if it has or hasn’t got data series appended to it. I tried setting the VisibleRange and VisibleRangeLimit when creating the axis, but still no results. Here’s a piece of the code:

new SCINumericAxis
{
   AxisAlignment = SCIAxisAlignment.Left,
   AxisId = "axis_id",
   TextFormatting = " 0%",
   VisibleRangeLimit = new SCIDoubleRange(-30, 100),
   VisibleRange = new SCIDoubleRange(-30, 100)
};

The Y values that we have are doubles, example:

[0]: 98.26171875
[1]: 0
[2]: NaN
[3]: 98.26171875
[4]: 0
[5]: NaN
[6]: 78.203125
[7]: NaN
[8]: 38.96484375
[9]: NaN
[10]: 98.28125
[11]: 0
[12]: NaN
[13]: 68.22265625
[14]: 0

So just by looking at the values, we should have a data range from 0 to 100, but I think somehow it messes up the conversion and ends up with ridiculously large numbers. I’m not doing any additional operations on the data, the printed data above is the data from the XyDataSeries. The Y type is Double, the YMin is 0, the YMax is 98, but still ends up drawing the values until 10000.
