Creating Chart with Excel (ActiveX)

Right now I'm writing the code for the output of an app I developed with the appdesigner, and I'm struggling to make it create a chart using Actx. I'm getting a strange error saying that the method for creating a chart cannot be found :/ Other than that all the commands that I've sent to excel are working just fine....

Line of code used:

 Chart=wb.ActiveSheet.ChartObjects.Add();

Any idea what's happening?

Thanks a lot in advance.

A lot of VBA examples on the net use Activexxx to refer to various objects. It always befuddles me since that breaks easily (something else, maybe the user, may change what is actually active).

Possibly, the ActiveSheet is not a worksheet to which a Chart object can be added. Rather than using ActiveSheet get the reference to the sheet you actually want to use:

ws = wb.Sheets.Item(sheetnameornumber);
chart = ws.ChartObjects.Add

If that still doesn't work, then I would break down the expression to see which part actually fails:

worksheets = wb.Worksheets;  %get the worksheet collection
ws = worksheets.Item(nameorindex);  %get a specific worksheet
chartobjects = ws.ChartObjects;   %get the chartobject collection of the worksheet
chart = chartobjects.Add;    %add a chart

I just found the problem. No idea why but my excel works with a method called "AddChart2"...................................................................... I literally hate vba....

AddChart2 is not a method of the Worksheet object. It is a method of the Shapes collection which is a completely different collection from the ChartObjects collection.

I just tried using ws.ChartObjects.Add and got the message ''Add' requires Model-Based Calibration Toolbox.' any advice?
