creating graph cursors dynamically

[Dipen]

Hello All,

I am a beginner with lab/windows CVI. I want to create a graph cursors dynamically.

Here is what I want to do,

Once a waveform is displayed i want to create graph cursors dynamically so I can choose different

parts of the waveform and adjust it to different time lengths.

I figured graph cursors are the best way to do it if there is any other better way please let me know.

Thanks in advance,

Dipen Shah

To dynamically activate cursors on a graph control you must set the appropriate number of cursors needed with the statement:

SetCtrlAttribute (panelHandle, PANEL_GRAPH, ATTR_NUM_CURSORS, numCurs);

After this, you can set the appropriate attributes for the cursors with:

SetCursorAttribute (panelHandle, PANEL_GRAPH, 1, ATTR_CURSOR_COLOR, VAL_RED);

In any case you may customize your cursors in the UIR editor, next put number of cursors to 0 before saving the UIR: the cursors will not be shown until you set their number as I showed you before.

Plot value at the cursor position can be obtained with:

GetGraphCursor (panelHandle, PANEL_GRAPH, 1, &x, &y);

Your graph must not be in indicator mode to be able to process cursor events.
