how to find left start value of the X-Axis in XY graph?

[MSS]

I want to find the start value of the XAxis and YAxis programmatically. I tried to get it by XScale.Range.Start property. But Its value and XScale.Range.Min are always same. What is the use on start property then? & how to get left start value of the X-Axis & bottom start value of the Y-Axis in XY graph?

Hi MSS,
read the XScale.Range.Start and YScale.Range.Start value. This works for me and i get the expected result.
See the attached example.

Hope it helps.

Hi MikeS81,

Thanks for your reply.

However same problem I find in your graph too. Please look in to the attachment. actually it should have returned 24 instead it returns 14.

Hi MSS,
you show your x scale inverted, so you have to read the max value.

Hi,

That is right. In my program I am trying to plot the mouse movement on graph. So I need to know the Left start value of X-Axis in addition to min and max of X-Axis. apart from all the XScale.RangeStart should return start property of graph right! why it should return same XScale.RangeMin value? Is it a bug in the LabVIEW program? In that case whom should we report?

Start is used for the grid calculations.

You could have a graph from 0 to 10 with a grid at all the uneven numbers. Then you set the start to '1' or '-1'.
Min should allways return the value 'left' value of an X-scale.
