Cursor z-axis reads 0 when negative scale offset is used in intensity graph

[Eyal]

I modified  xscale.offset and yscale.offset to negative values by half the array size on each axis, to see point (0,0) at the center of an intensity graph.

When the cursor is in the negative 3 quadrants, it reads 0 on z-axis.

When it is on the first quadrant, z-axis starts to show the 2D array data, starting at element (0,0) of the array, although it is at the center of the graph. 

The xscale.offset and yscale.offset do not modify the cursor correctly, to show the 2D array data at the cursor location.

I use LV 8.0.

Did anyone face this problem?

Any solution?

I cannot reproduce this. Can you attach a simplified example that shows the problem?

Actually, I take that back. I can reproduce this. The problem occurs only for "free" cursors. It works fine for "single plot" cursors in 8.0

(See attached: green: free cursor, yellow: single-plot cursor) 

I tried the same in 8.2.1 and 8.5.1 and everything works as expected. The problem only occurs in 8.0. TIme to upgrade. 😉

As a workaround, use a "single-plot" cursor.

Thank you - "single-plot" works fine.
