Native chart color palette is not preserved

Hi,

Here I’m opening a workbook with a chart that have a color palette applied (see image inputColorPalette.png in the attached zip file). When adding values to the chart (see attached Visual Studio project) and saving the workbook, chart seems to have lost the applied color palette (see outputColorPalette.png)

Best regards

@andreagasparin,
I have tried to reproduce this issue here but could not observe the view shared in your images. Could you please share which MS Excel are you using and share exact steps to observe this problem?

Hi,

This is the Excel version I am using
image.png (1.1 KB)

When opening the input.xlsx file (you can find it in the attached zip) you can follow these steps:

  • select the chart in the first sheet
  • go under “Chart Design” in the ribbon
  • open the “Change colors” menu: here you can see that the second option is select
    image.png (23.1 KB)

If you do the same with output.xlsx you can see that no color scheme is selected

Hi all,

Unfortunately this issue is still present when saving xlsx file to stream and opening it as a Workbook again. I’ve replicated in the attached sample project. The code is basically this:

var wb = new Workbook(inputFileName); // original file, chart with a color pallette 

wb.Save(path + "openedAndSaved_noissue.xlsx", SaveFormat.Xlsx); // here chart still have color palette applied

// save workbook to stream and read from stream
using (var refreshStream = new MemoryStream())
{
     wb.Save(refreshStream, SaveFormat.Xlsx);
     refreshStream.Position = 0;
     var resultWorkbook = new Workbook(refreshStream);
     resultWorkbook.Save(path + "savedToStream_issue.xlsx", SaveFormat.Xlsx); // here there is no more color palette 
}
