Pie Chart Callouts with MSChart

Sorry, search is disabled.

I'm sure there is a better way to do this, and if so, please volunteer.

I have an ActiveX DLL that is feed an multidimension array of numbers by a VBScript ASP. The DLL creates a pie chart, dumps it to a bmp, converts it to a jpg, and returns the file name to the ASP. There it is included in an img tag.

As far as I know I have to use the DLL, the ASP can't create an MSChart object and put it on the page, can it?

My question is, is there a way to do call outs for the DataPointLabel. Right now they are all VtChLabelLocationTypeOutside, but when the last few slices are small (0-2%), the labels run over each other. Thus the need for call outs.

Since I don't see any documentation, I imagine I can't do it. Has anyone used Offset to do the same thing?
