how to extend controls

[Thomasschoenau]

I'd like to midify or extend controls.

For example:

I want a XY-Graph, that shows the coordinates of the mouse in two indicators below the graph.

So I have to get the coordinates via the MouseMove - event and to transforme them into the coordinates of the xy-graph.

This is no problem so far...

But if I want to use this modified XY-graph in other LV-projects, I have to copy this big circuit with all its functions and wires.

I would prefer to assign a small symbol to this modified XY-graph. So I could use this modification as easy as it would be in the case of a normal xy-graph.

The problem I describe is a bit similar to the sub-VIs, but I want to combine several functions AND controls to one symbol.

Is this possible?

If not: How do you reuse already built VIs? Do you always copy/paste these big circuits?

hello thomas,

it sounds, that a X-Control might be useful in the application you describe.
take a look at this article:
Creating New Front Panel Objects with LabVIEW XControls

with X-Controls you can add functionality to a control and use it in different projects.

i hope this helps,
kind regards,
