thanks so much.

Hello tungu123,

I am very sorry but I am a little confused about your question.  Would you mind clarifying your question a little more?  Are you talking about the X-Y Graph in LabVIEW or is this something related to Motion?  If it deals with the attributes available for different LabVIEW controls such as the X-Y graph then you can post your question in the LabVIEW Forum.  If this is motion related then I apologize and ask you to either explain in more detail or/and post a picture of what you are talking about.  Thanks and have a great day.

thanks Mart,

in this case, the xy graph is changed to control condition (normally it is in indicator condition). i will use mouse to draw the circle, line.. on this xy graph. but i can not draw with this case.
if i can draw, next step i will get thes data of thi\ese circles, lines.. analysis them and export to stepper motors to  make the model moving in 2d axis.

sincerely,
Tung

Hello tungu123,

There is actually a very simple example that is shipped with LabVIEW that shows how you can draw on an X-Y graph.  You then need only to use the output array of clusters in the example to get all of the points.  The name of the example is:  "Draw Graph With Events".  You can find it by searching for the title in the example finder.  This should get you started.  I hope this helps.  Thanks and have a great day.
