Data is not displayed in .png file

When I put MarkerStyle = ChartMarkerType.Picture data is not displayed in .png file.

Hi,

Thanks for your inquiry.
When creating the default ScatterStraightLinesAndMarkers, there would be only 3 series, so you need to comment out following code, otherwise there would be an exception.

Code: Select all

chart.Series[8].MarkerStyle = ChartMarkerType.Picture;

And after testing with Spire.Presentation Pack Hotfix Version:3.12.4, I could get correct image. Attached is my result file for your kind reference.
Please make sure you were using the latest version I mentioned.

But in the presentation, everything works. I need to work with ChartMarkerType.Picture. I need this so that the markers were not visible in the presentation, but that the type remained scatter with straight lines and markers. If I just install ChartMarkerType.None, then the chart type changes to the Scatter line with straight lines. Maybe you know another solution?

Hi,

Sorry for my mistake that I used wrong series number "8" instead of "0".
As for your requirement "markers were not visible in the presentation", could you please provide your expected PPT file? Then I will provide corresponding code for you.

Thanks,

If I use ChartMarkerType.None then the chart type will change from Scatter with straight lines and markers to Scatter with straight lines, and I need Scatter with straight lines and markers. So I used ChartMarkerType.Picture. That makes it possible to be invisible markers and not to change the type of chart , but data in png is not displayed.

Hi,

Many thanks for your information.
Now I am clear about your requirement(marker is invisible and the chart type cannot be changed). And I had noticed the data in .png was missing before and posted the issue to our Dev team. We will let you know once there is any update.
Sorry for the inconvenience caused.
