Scatter XY points connected with line?
Posted by achar on Jan-11-2022 17:07	\| Reply \| Monitor
Hello, I just bought the product and while browsing the sample code I cannot find an easy way to produce XY scatter data connected with a line, just like Excel. Do I have to manually add lines between points in the scatter plot? I do not want to miss something obvious here. TIA

Hi achar,

The followings are some examples. (The followings are .NET examples. They are available in other programming language editions of ChartDirector as well.)

In brief, the code is like:

LineLayer layer0 = c.addLineLayer2();
layer0.addDataSet(data0Y, 0xff0000, "Quantum Computer").setDataSymbol(
Chart.GlassSphere2Shape, 11);
layer0.setXData(data0X);
layer0.setLineWidth(3);

Hope this can help.

Regards
