Re: drawing limits lines in cwgraph

[Jervin_J]

Hi hrsnblm,
You can achieve this fairly easily using cursors.
For example, I'm working off the Simple Graph example located at:C:\Documents and Settings\All Users\Documents\National Instruments\MStudioVS6\VB\Samples\UI\Graph\Simple Graph
What I did was:

- Right click the graph and click Properties

- Select Cursors tab

- Add two cursors (using the Add button) and change their Crosshair Style to Major Y Only

- Close out of the Properties dialog

- In the code, set the YPosition attribute of the cursor using something similar to:CWGraph1.Cursors(1).YPosition = 8CWGraph1.Cursors(2).YPosition = 2

Thank you for your help. This gets me started. The limits lines I will need to draw will not be horizontal, but angled to represent the limits of a slope. Can I set the run statement "CWGraph1.Cursors(2).YPosition = " equal to the slope equation for the limit line, or is there a different way to represent such a limit line?

Thanks for your assistance.
