Thread: Need help regarding ActiveX Chart Object

Greetings!

Currently I'm developing a measurement software. For this software I need to use a chart (like one in Excel).
I use Borland C++ Builder 5. Upon installation, some ActiveX components were installed, and among these components I found an ActiveX chart element. It's called TVtChart , and I tried to use it.

My problems are the following.
-I'd like to fill the chart with data from an integer array
-To do that, I have to convert the integer array to an OLE type variable. This is the first thing I cannot do.
-I don't have any normal kind of desctription of this component, and I don't know the usage of the functions of this object.
-I never used OLE variables before, so I don't really know what to do with them.

So if you can help me in these questions, or you know a freeware chart component on the web, then please don't hesitate to write.

I trust in you guys, you've helped me out several times.

Best Regards,
Han

A bit of satisfaction. I found the description, it is called VTChart, not TVtChart as mentioned. This is part of the problem.
Be back, if I get further with the other things.

Well my is problem still there. I cannot write into the ActiveX Chart. I don't clearly see the structure of the whole thing. (Maybe it's just too late for that here 23:38.)
