I have been working with the new Overview Chart feature available in the new 2.0.0-beta.2084 release, and ran into an issue where I can remove lines from the overview surface no problem, but then I always receive an error whenever I try to add one.

I was just wondering if there is a recommended flow for when a parent chart’s renderable series array has traces added or removed. One thing I did try to circumvent this issue was to delete the old overview and add a new one, but I receive either a separate error or the overview would draw without any traces.

I have attached a file with example code that should display the error I receive when you add a line to an overview component. I have also attached an image of the error that appears in the console.

Hello Drew,

Accordingly to the error message you can’t attach the same Renderable Series to different surfaces.
The described issue is caused by the following code:

        if (scichartOverview !== null) {

where you are trying to add “newLineSeries” into different collections.

So to resolve the issue, you can create a copy of the “newLineSeries” and pass it separately:

       const options = {
            dataSeries: dataseries,
            strokeThickness: 2,
            stroke: newColor
        const newLineSeries = new FastLineRenderableSeries(wasmContext, options);
        const newLineSeriesForOverview = new FastLineRenderableSeries(wasmContext, options);

        if (scichartOverview !== null) {

Now you will have 2 instances of FastLineRenderableSeries which will use the same dataSeries.

Best Regards,
