Question

I want to select existing Chart in Excel using C#.
I have a chart Object in my excel file which I want to read it and also Edit it.
I only know to add new chart which is by doing something like this

ChartObjects ChartObjs = null;
ChartObject ChartObj = null;


 ChartObj = ChartObjs.Add(0, 10, 250, 170);

I am using VS 2005 and C#

To select an active chart in excel one can use this code

Excel.ChartObject chartObject11 = (Excel.ChartObject)Ws.ChartObjects(1);
chartObject11.Activate();

based on this one can edit the chart and format it.Like changing its datarange or formatting its color or height or width etc etc.

Hope this helps
