I've got a ScatterChart set up that shows data that is both positive and negative on the Y axis. I'd like to have a horizontal red line on the chart that shows where Y = 0.
What is the preferred way of doing this? Is there a setting I'm missing, would I need to override a paint event, or would I need to set up a second datatable to plot the line?
Update: I've found the FillSceneGraph event in another message, and will upgrade from 7.1 to 7.3 and give that a try.
Okay, I've upgraded to 7.3 and have been able to add a sample line to the chart.
The line I added was in screen coordinates, but are there any tools to help convert graph coordinates into screen coordinates, as well as to determine the minimum and maximum bounds of the graph coordinates?
