Hello,

I need to get point of x and y axis in line graph.
Is there any method to get it?
I want to make the point of color is red when it is positive, and the point of color is green when it is negative.
so,i need every point of x and y axis.

Thanks!

Hi there,

There's no way to get the X value of a Line chart - there's no scale. For that you would need the Scatter chart with a connecting line so it looks similar to the Line hart.

Then there's the obj.getXValue() and obj.getXCoord() functions which you can use to get the information you need.

Then you can use the RGraph.Drawing.Circle() to add a circle using those coordinates.


PS Could you link to the RGraph website - thanks.
