Updating chart in word document

Hey

I am creating a report and as part of the report we have to show few charts. I am working of a template doc and it has sample editable pie/bar charts.

I try to find the chart and then update the values with the report values. However the chart color is changed from the template doc.

The same doesn't happend when I create a pptx report . The updated charts take the color of the template file. However for ppt I could get the workbook of the chart and update the values of the excel.

For word document i couldnt get the workbook of the editable chart. Why is this so? I am trying for past few days. Any help would be great.

Thanks

Aspose.Words.Drawing.Charts.Chart FindChart(Document document, string chartName)

{var shapes = document.GetChildNodes(NodeType.Shape, true).ToArray();

foreach(Shape shape in shapes)

{

if(shape.HasChart)

{

if(shape.Name == chartName){

return shape.Chart ;}               

}}returnnull;}
