Could you please help me write a code snippet to draw chart on ppt provided in the zip file.
If possible I need a code snippet with cells to plot chart in Excel. For same example
@VaradS,
Thank you for the sample chart. Unfortunately, I was unable to write a code example to create the chart you provided.

Thanks for the code example, could you help me with setting following configs to series for the chart in Excel. Using Cells library.
static void setArrowheadStyles(IChartSeries series)
{
series.getMarker().setSymbol(MarkerStyleType.None);
series.getFormat().getLine().setBeginArrowheadStyle(LineArrowheadStyle.Diamond);
series.getFormat().getLine().setBeginArrowheadWidth(LineArrowheadWidth.Wide);
series.getFormat().getLine().setBeginArrowheadLength(LineArrowheadLength.Long);
series.getFormat().getLine().setEndArrowheadStyle(LineArrowheadStyle.Oval);
series.getFormat().getLine().setEndArrowheadWidth(LineArrowheadWidth.Wide);
series.getFormat().getLine().setEndArrowheadLength(LineArrowheadLength.Long);
}
@VaradS,
Please contact my colleagues on the Aspose.Cells forum. They will be happy to help you with this.
Hi @andrey.potapov and team,
Could you please let me know how to change color of series here?
currently we have green color for euSeries I want dark blue shade instead.
@VaradS,
Thank you for your patience. To change the color of the series, you can use the ILineFormat interface as below:
Color euSeriesColor = new Color(0, 0, 200);
ILineFormat lineFillFormat = euSeries.getFormat().getLine();
lineFillFormat.getFillFormat().setFillType(FillType.Solid);
lineFillFormat.getFillFormat().getSolidFillColor().setColor(euSeriesColor);

Thanks for your reply, whenever I’m applying color using these lines. I’m not getting the lines itself.
If we see the series configs in ppt for line I can see the solid line is selected. Do you think any extra setting I’m doing which can cause this issue?
