How to replace data behind a chart

[majeed_s]

Apologies if this information already exists but I want to replace the data behind a specific chart. Is there a built in method to do this? Is there an example?

Also, do all the charts use the same method or each chart has its own unique approach.

Links to documentation where I can learn more would be great also.

Hello,

Thank you for your inquiry.
Do you want to modify the data source of chart? If yes, please refer to the following code. If this does not meet your needs, please provide further information, sharing your input PowerPoint files and expected result files will be helpful. You could attach them here or send them to us via email (support@e-iceblue.com). Thanks in advance.

Code: Select all

Presentation ppt = new Presentation();
ppt.LoadFromFile("input.pptx");
IChart chart = ppt.Slides[0].Shapes[0] as IChart;
chart.ChartData[1, 1].Value = newData;
...
ppt.SaveToFile("output.pptx", FileFormat.Pptx2010);
