restrict the movement of cursors on xy graph

[diego77]

hello.

I have an XY graph, with values of 0-10 in X, and of 0-10 in Y. I have two cursors in the graph.

I do not want the cursor is out of the graph area of 10 * 10, I disabled the auto scale, but the cursor can get out of the area of 10 * 10.

I also hope that the value of X of the cursor0 does not exceed the value of X of the cursor1.

I hope you can help me with these restrictions on movement, thank you very much.

Right click on the graph and unselect Advanced>Cursors Scroll Graph.

that's excellent, thank you.

Now I only need restrict that the value of X of the cursor0 does not exceed the value of X of the cursor1 when moving the cursors.

Hey there, If you want to restrict the value of the cursors you can use property nodes to do so..

Here is an example; you just need to get the value on X of the active cursor (0 or 1) and then compare those values; if the value is smaller; you can use a case structure and a property node to coerce the values.

Hope this info helps.

If your UI is using an event structure (of course it is, right?), you can register for various cursor grab/move/release events on the XY graph.  That way you don't have to poll for where the cursors are all the time.
