paletteProvider transparent colour is not working.

I tried with parseColorToUIntArgb(“#ffffff00”) and parseColorToUIntArgb(“#ffffff00”, 0) to replace the colour with transparent. But its not working.

I want ho hide the marker on the chart if the value is less than a limit. Is any other possibility to hide the marker based on value?
can you check the image, i want to show only the yellow marker.
one more error i am getting from typescript
“Type ‘undefined’ is not assignable to type ‘TPointMarkerArgb'”.

The value of SciChart in Silverlight is the browser hosting capability. With Silveright on its way out, there appears to be no replacement for SciChart in a browser. However, there is a very good public domain project called Fayde that has re-implemented the Mono Moonlight code as Typescript. Fayde lets you port C#/XAML to Javascript surprisingly easily.

Have you looked at Fayde, and do you foresee a (possibly stripped-down) SciChart version for Fayde?

Some users have reported an error when importing SciChart.js into a TypeScript or JavaScript application:

TS1261: Already included file name ‘C:...\SciChartSurface.d.ts’ differs from file name ‘C:/…/node_modules/scichart/charting/
Visuals/Axis/SciChartSurface.d.ts’ only in casing.

Hello,
I am trying to make an annotation draggable. I tried setting the isEditable property to true, but nothing happened. I can’t find the right documentation for draggable annotations . My code for creating the Annotation it’s below:

sciChartSurface.annotations.add(new LineAnnotation({
    stroke: "#279B27", strokeThickness: 3,
    xCoordinateMode: ECoordinateMode.DataValue,
    x1: 0,
    x2: 0,
    yCoordinateMode: ECoordinateMode.Relative,
    y1: 0,
    y2: 1,
    isEditable: true,
}));

Multiple instances of sci chart any appearance changes reflecting on other instances. When I changed the background of one instance the same is reflected in the other instance. I have updated with createSingle to resolve this issue, But i am getting one alert when using createSingle.

I am getting a console error when using isVisible: false to the FastLineRenderableSeries or FastMountainRenderableSeries and CursorModifier together.

If the y axis values are same then the lines are not visible on the chart and the labels are also not visible on the chart. Can you draw the lines on the middle of the chart to get more visible?

async initTrack() {
  const { wasmContext, sciChartSurface } = await SciChartSurface.create(
    "chart" + this.element
  );
  sciChartSurface.xAxes.add(
    new NumericAxis(wasmContext, { axisAlignment: EAxisAlignment.Top })
  );
  sciChartSurface.yAxes.add(
    new NumericAxis(wasmContext, {
      axisAlignment: EAxisAlignment.Left
    })
  );

  const dataSeries = new XyDataSeries(wasmContext);
  for (let i = 0; i <= 1000; i++) {
    dataSeries.append(i, 10);
  }

  const rendSeries = new FastLineRenderableSeries(wasmContext, {
    dataSeries: dataSeries,
    strokeThickness: 1,
    stroke: "red"
  });
  sciChartSurface.renderableSeries.add(rendSeries);
  sciChartSurface.chartModifiers.add(cursorModifier);

  return { wasmContext, sciChartSurface };
}
