I have 2 charts in my application. They work fine until I add an event to the chart (xaml). The Designer gives an Unhandled Exception with the following details

  1. SciChartSurface created with category x and numeric y axes
  2. ZoomPanModifier, ZoomExtentsModifier, MouseWheelZoomModifier, RolloverModifier added.
  3. Any series and dataSeries are initialized and added to the surface, but not filled with values yet.
  4. Value streaming started with delay.

The first error occurs when trying to zoom on empty surface :

Uncaught TypeError: Cannot read properties of undefined (reading 'width')
at MouseWheelZoomModifier2.ChartModifierBase2D2.growBy (ChartModifierBase2D.js:121:48)

And the other one when trying to drag:

Uncaught Error: category x axis with id=DefaultAxisId should have data series count > 0
at CategoryAxis2.CategoryAxisBase2.getCurrentCoordinateCalculatorInternal (CategoryAxisBase.js:95:19)

I have seen errors similar to the second one in other scenarios and sometimes it is fatal.
E.g i have tried to add annotation right after first value was added and first line raised similar error:

    const xCalc = this.surface.xAxes.get(0).getCurrentCoordinateCalculator() as CategoryCoordinateCalculator;
    const realX = xCalc.transformDataToIndex(time);
    const target = this.getOrAddAnnotation();
    target.x1 = realX;
    target.y1 = value;

Also getCurrentCoordinateCalculatorInternal error occurs when empty series & seriesData added without suspend.
I would appreciate any help and clarification

We found that when the entered data is wrong and SciChart exception occurs, we can’t get back to normal without F5 reloading.

In our application, when switching the symbol/screen, it will start over from SciChartSurface.create(), but it just cannot return to normal.

If the abnormal data causes scichart exception, what can we do to minimize the damage ?

Hello, I just started evaluating your 2D JS chart library and am running into an error (below) and don’t know what I should do to continue forward:

Error:

wasm streaming compile failed: TypeError: Failed to execute ‘compile’
on ‘WebAssembly’: Incorrect response MIME type. Expected
‘application/wasm’.

Could not load SciChart WebAssembly module.
Check your build process and ensure that your scichart2d.wasm, scichart2d.data and scichart2d.js files are from the same version

Uncaught (in promise) Could not load SciChart WebAssembly module.
Check your build process and ensure that your scichart2d.wasm, scichart2d.data and scichart2d.js files are from the same version


I am copying the scichart2d.data and scichart2d.wasm in my webpack config as follows (according to your tutorials):

config.plugins.push(
    new CopyPlugin({
        patterns: [
            // {
            //     from: 'src/index.html',
            //     to: '',
            // },
            {
                from: 'node_modules/scichart/_wasm/scichart2d.data',
                to: '',
            },
            {
                from: 'node_modules/scichart/_wasm/scichart2d.wasm',
                to: '',
            },
        ],
    })

I have since then done the following but to no avail:

  1. Restart my webpack-dev-server -> In chrome, “Empty cache and refresh”
  2. Delete my node_modules folder -> yarn install -> yarn start

Can someone please help me with this issue at an earliest convenience.

Hi,

I’m evaluating SciChart for use in a production app.

Is there any way to log exceptions generated by SciChart? Currently I’m logging all handled and unhandled exceptions in my app to my server so that issues can be flagged without users having to manually submit support tickets. SciChart is printing internal exceptions to console – is there any way to override that with our own error handling mechanism? If not, how should we monitor for production errors generated internally by SciChart?

Thanks

hi everyone
when i use utf8 string such as ‘محور’ = axis in persian sciChart lookLike this .
i tried different fonts but did not work .

 SciChartBuilder.init(this@Main2Activity)

    // Obtain the SciChartBuilder instance
    val sciChartBuilder = SciChartBuilder.instance()

    val myCustomFont: Typeface? = ResourcesCompat.getFont(this, R.font.maryam)
    val fontStyle = FontStyle(myCustomFont, 50f, Color.RED)

    val s = String("محور".toByteArray(Charsets.UTF_8))

    xAxis = sciChartBuilder.newNumericAxis().withAxisTitleStyle(fontStyle).withAxisTitle(s).withGrowBy(DoubleRange(0.1, 0.1)).build()
    yAxis = sciChartBuilder.newNumericAxis().withAxisTitle("this is y").withGrowBy(DoubleRange(0.1, 0.1)).build()

    val dataSeries = XyDataSeries(Double::class.javaObjectType, Double::class.javaObjectType)
    dataSeries.append(arrayOf(0.0, 2.0, 4.0, 6.0, 8.0, 10.0), arrayOf(1.0, 5.0, -5.0, -10.0, 10.0, 3.0))

    rs = sciChartBuilder.newColumnSeries()
            .withDataSeries(dataSeries)
            .withStrokeStyle(ColorUtil.White, 3f, false)
            .build()

    surface.chartModifiers.add(sciChartBuilder.newModifierGroupWithDefaultModifiers().build())

    UpdateSuspender.using(surface) {
        Collections.addAll<IAxis>(surface.xAxes, xAxis)
        Collections.addAll<IAxis>(surface.yAxes, yAxis)
        Collections.addAll<FastColumnRenderableSeries>(surface.renderableSeries, rs)

    }

and the result :

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

I am creating a chart to represent certain vitals. The code is almost identical to the Vitals Monitoring Demo application, the difference being
I added some Line and text annotations. I am appending points to the data series every 100ms. I have verified that the anomalous behavior is not caused due to wrong data being provided,
leading me to believe it must be a bug within SciChart. I have attached screenshots of this anomalous behavior. Any help would be greatly appreciated. Thank you.

Edit: This happens randomly, ie it performs normally without glitches on application startup but misbehaves after left running for a while.
I also observed that when I call .clear() on the XyDataSeries objects, the graph returns to normalcy, but only until FIFO_CAPACITY is reached. It then goes back to wreaking havoc.
I have added sample data (data.txt) to the question for reference, and screenshots of Expected behavior and the abnormal behavior in question.

Gif of the problem is here: https://imgur.com/7SO4DFb

Code used for setting up the chart:

Was created react-native-charts-sci wrapper for Scichart with the structure – [Screenshot _1]. And now need to publish this package to npm private repo, but Scichart.framework folder is vast (~100 MB) and its connect in current podspec file – [Screenshot_2] like a local directory:

spec.public_header_files = “ios/SciChart.frameworks/Headers/*”
spec.vendored_frameworks = “ios/SciChart.framework”

Need to connect Scichart.framework in wrapper library like subspec that it could be taken during the installation process from vendor’s podspec repo: https://github.com/ABTSoftware/PodSpecs/tree/master/SciChart. The goal is to decrease of wrapper library folder size that would be possible to publish it to npm repo.

After adding Scichart.framework like subspec – [Screenshot_4] to podspec, get the errors after pod install – [Screenshot_3]:
– ERROR | [iOS] attributes: Can’t set version attribute for subspecs (in react-native-charts-sci/SciChart).
– ERROR | [iOS] attributes: Can’t set authors attribute for subspecs (in react-native-charts-sci/SciChart).
– ERROR | [iOS] attributes: Can’t set license attribute for subspecs (in react-native-charts-sci/SciChart).
– ERROR | [iOS] attributes: Can’t set homepage attribute for subspecs (in react-native-charts-sci/SciChart).
– ERROR | [iOS] attributes: Can’t set source attribute for subspecs (in react-native-charts-sci/SciChart).
– ERROR | [iOS] attributes: Can’t set summary attribute for subspecs (in react-native-charts-sci/SciChart).
– ERROR | [iOS] attributes: Can’t set documentation_url attribute for subspecs (in react-native-charts-sci/SciChart).

Can you tell me please is it possible to get Scichart.framework from vendor’s podspec repo: https://github.com/ABTSoftware/PodSpecs/tree/master/SciChart and connect it like a subspec in podspec file? Need to create LICENSE.txt with the licence and write the pass of it in podspec file? Can you provide some examples with the correct way to do it? Why get this errors? What’s wrong with the current framework connection?

Hello,

I have a SciChartSurface with multiple StackedColumnRenderableSeries. The goal is to create a column style “Stacked Graph”.

The StackedColumnRenderableSeries are created this way:

private StackedColumnRenderableSeries[] m_layers = new StackedColumnRenderableSeries[0];
  -------
    while (num  > m_layers.Length)
              {                
                  StackedColumnRenderableSeries layer = new StackedColumnRenderableSeries()
                  {
                      DataPointWidth = 0.9,                  
                      Fill = new SolidColorBrush(DefaultMainColorOfCurrentSetting),
                      Stroke = Colors.Black,
                      ShowLabel = false  
                  };
  
                      layer.DataSeries = new XyDataSeries<double, double>();
                      layer.DataSeries.AcceptsUnsortedData = true;
  
                  m_sciChartSurface.RenderableSeries.Add(layer);
                 
                  List<StackedColumnRenderableSeries> temp = m_layers.ToList();
                  temp.Add(layer);
                  m_layers = temp.ToArray();
                 
              }
  

Later, they are fed data with this function:

void addBar(double[] layerValues)
          {
  
              using (m_sciChartSurface.SuspendUpdates())
              {   
                  for (int i = 0; i < m_layers.Length; i++)
                  {
                      XyDataSeries<double, double> data = (XyDataSeries<double, double>)m_layers[i].DataSeries;   
                      data.Append(m_currentTimepoint, layerValues[i]);
                  }
              }
  
              m_currentTimepoint++;
          }
  
  private int m_currentTimepoint = 1;
  

If I use this function within the class constructor, everything works as expected (see attached image).

However, sometimes, I receive the error message “”System.ArgumentException” in SciChart.Charting.dll The StackedColumnRenderableSeries type requires that all stacked stacked series with the same StackedGroupId have the same XValues.”

I fail to see the meaning of this message, since, the x-Value is the same for each part of the new column. Its “m_currentTimepoint”.

Additional Information:

This visualization is part of a medical monitoring software we are currently developing. If we use test data to call the addBar-Function (directly from the constructor, for example), the error does not appear. However, if we use data from our medical sensors, it appears. In both cases, the addBar-Function receives valid data (no NaN´s or such things)

The function is not called often, about once every 10 seconds.

Thank you

After installing the SciChart Licensing Wizard (for current user only), the Wizard hangs and does not display anything, which means I cannot activate the my license.
