Blank chart when exporting WordCloud chart

[dritani]

Question
Hello, when exporting a WordCloud chart I am getting a blank image since it takes some time to perform word arrangement. In AmCharts 4 there exists this workaround but I could not get it to work with AmCharts 5.

Does someone know how to accomplish this? Thank you.

Environment

AmCharts 5.8.0
Chrome 124.0.6367.208

Do you have a demo of where export of a chart does not work?

I tried it just now, and was able to export a PNG of a WordCloud just fine.

The code is pretty deep within a React.js app but the gist of it is:

    am5wc.WordCloud.new(root, {
        categoryField: 'customCategory',
        valueField: 'customValue',
        angles: [0, 90],
      }),

  const exporting = am5Exporting.Exporting.new(root, {
    extraImages,
    filePrefix: 'chart',
  });

  exporting.download('png');

I tried using setTimeout or listening to the datavalidated event but it still did not work.

Do you get any errors in console? Does this happen in all browsers?

Here's my test:

Did you also try removing extraImages?

Or significantly delaying the exporting.download('png') call?

[dritani]

Yes I tried adding multiple seconds delay for exporting.download('png') and removing extraImages. Have done extensive tests but nothing worked. The export is being triggered programmatically and not through the menu.

Can you reproduce it on this CodePen?

It triggers a download after 5 seconds.

I wasn't able to reproduce it. We deployed the feature without WordCloud export for now.

Have you tried it with the latest version of amCharts? 5.9.11
