How can i edit graphs on front panel?

[Tamas]

Hello!

My problem is the following:

I need a front panel, where i can edit the graph. It doesn't need to be very complicatted. It means, there is 5 steps. For example: It will control a thermal chamber, and it should give 25 celsius for 2 hours, then cool down until 2 hours to -40 celsius, 4 hours on -40, then back to 25 celsius until 2 hours, stay there for 2 hours, up to 105 celsius until 2 hours, 4 hours on 105 , 2 hours down to room constant, stay 2 hours there. But i need to be control the levels. The temperature levels, and the time periods. It's nessesery to control this on front panel. I've found a vi , which is reading in *.lvm files with datas x,y and then it's interpolating. But it is not setable after setting.

Please help me. Thank You very much!

If you want to specify the profile graphically then you can use cursors to do it. An old example can be found here. You may find others by doing your own search (hint, hint).

Otherwise, you can simply use a multicolumn listbox to specify the indvidual profile segments, and a graph can be used to display the entered profile whenever the listbox changes.
