After converting to html, chart is empty.
I noticed that the problem arises in the case of presence hidden column.
Here is an example:
var workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];
worksheet.Cells["K1"].PutValue(50);
worksheet.Cells["K2"].PutValue(120);
worksheet.Cells["K3"].PutValue(160);
worksheet.Cells["K4"].PutValue(200);
worksheet.Cells["L1"].PutValue(4);
worksheet.Cells["L2"].PutValue(20);
worksheet.Cells["L3"].PutValue(40);
worksheet.Cells["L4"].PutValue(120);
worksheet.Cells.Columns[10].IsHidden = true;
worksheet.Cells.Columns[11].IsHidden = true;
int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Line, 0, 0, 20, 7);
Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];
chart.PlotVisibleCells = false;
int index = chart.NSeries.Add("K1:K4", true);
chart.NSeries[index].LegendEntry.IsDeleted = true;
chart.NSeries.Add("L1:L4", true);
var htmlSaveOptions = new HtmlSaveOptions
{
HiddenColDisplayType = HtmlHiddenColDisplayType.Remove,
ImageOptions =
{
ImageFormat = ImageFormat.Png
}
};
workbook.Save("c:/test.html", htmlSaveOptions);
