 |
|
I have been trying to use VtChart. I have seen some references to TChart. I presume that TChart is the product of a base class that I haven't used before. Is it available with the personal version of Borland Builder? Is there an example of its implementation to produce a scatter chart with more than one series of points and X values that do not correspond to X value array integer numbering somewhere? THANKS.

It is derived from TPanel.

I don't know. I use Enterprise.

I doubt it because it's very simple:
TPointSeries *PointSeries = new TPointSeries( Chart1 );
for( int x = 0; x < 10; ++x )
{
PointSeries->AddXY( x, x*2, "", clBlack );
}
Chart1->AddSeries( PointSeries );

TChart has nothing to do with VtChart. VtChart is an ActiveX-only
component. When I tried to find the parent company on the Web
(it's link is supposed to be [url]http://www.visualcomp.com)[/url], my
browser can't find it.
TChart is also from a third-party but the company is still
around and is actively improving it. The version that comes
free with Builder allows you to embed all the code for the
charts in your program so you don't have to load and register
and ActiveX component. But, there is an ActiveX version of
TChart available, too.
You may find TChart a little intimidating to use at first
because it is so flexible and powerful but it is worth
learning.
The company (Steema Software) that makes TChart is found at:

Thanks! I just wish that the documentation for VtChart was |
more complete. What I need to do seems simple (setting data points), but I can't find an example that works in the help file. I can't use the Chartfx version that shipped with Builder, because the ability to hide points appears to not exist with this old version, so I can't plot two series with different quantities of points without randomly generating a lot of meaningless points, or adding points through interpolation that might confuse the user. I do appreciate your response, and will try to get TChart to work.

Sure you can. You can use the sample that I gave you to add
multiple TPointSeries and they can also be selectively removed
as well.

The TPointSeries data type is not defined. Is there
a header file that must be loaded to use this TChart
object? Thanks!

After all of the header files it dropped into the form's header, you'd think that it could get all of them.
It missed Series.hpp.
How I determined that was to perform a search within files for
'TPointSeries'. The results showed me that the constructor
was defined in Series.hpp.
