Inverting chart / series colors automatically

[MWeingarden]

I am displaying a chart (FastLine Series) in 2 different modes, one that is updated in real time, and one that shows past data. When real time mode is selected, I would like to invert the colors of the Chart, Axes, Titles, Series, automatically. Is there any easy way to do this?

Thank you.

Hello Weingarden,

You could use Themes feature for this. You can create two custom themes, one for each mode, and set them when needed.
Take a look at this article on the blog:

The themes certainly will help out. Are there any examples in C++? When I try to compile ApplyChartTheme using one of the TXxxthemes as a parameter, I am getting an error. What is the correct way to call the routine in C++ (Rad Studio XE7)?

Thank you

Hello,

Apologies for the delayed reply here.

You can call ApplyChartTheme in C++ Builder like this:

Code: Select all

  TFlatTheme * flat = new TFlatTheme(Chart1);
  ApplyChartTheme(flat->ClassType(),Chart1);
