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
