Summary0015064: (Venus) plot over line doesn't correctly reset
DescriptionWhen re-targeting inputs to plot over line, it doesn't correctly reset. Although this sequence sounds strange, it is used all the time by my user. He is setting up a complex set of 2d plots, and trying to reuse the same setup for multiple files. Save/restore state is failing for him.

Linux, 4.2.0, local server, auto apply on (although I bet it doesn't matter.)

* Sources/ line.
* Calculator. (Correct, no input formula.)
* Plot over line. Notice the X and Y extents. Both are 0-1.
* Sources line. Change the X coordinate of point 1 to be -5, point 2 to be 5. We now have a line that is 1
* Right click on the Calculator in the pipeline browser, and "change input". Change it to line 2.

<<Bug>> Notice that the line will shift, as it should, but the X axis doesn't change. Further, the green line appears to go into negative line space. This is probably misrepresenting data.

If you run plot over line from line2, you can see what should be happening - the X axis goes from 0 to 10.

 Targeting 4.3, since this is misrepresenting data.

 The X-axis is not expected to change. If you look at the Properties panel for the "Plot Over Line" in the "Line Chart View", the "X Array Name" is set to "arc_length" by default. This is the length of the probe line (used for the probing operation) which wasn't changed when you changed inputs and hence it will remain 0-1.

If you run a new "Plot Over Line" on Line2, the Point1 and Point2 on this filter will be reset to the values in the data i.e. [-5,5] and hence it will go from 0-10.

Changing inputs is not expected to change properties on the filters. YOu can reset to the new range after you change the input by clicking the "X Axis" button, for example.

I do not understand the "negative line space" comment.

 Why shouldn't the arc_length change if you change the input filter? Seems to me that it should...

Ignore my "negative line space" comment. I was being brain dead....

 'arc_length' cannot change.

There are two parts here:
(a) The data being probed *into* (which in your case is Line1 and Line2 sources).
(b) The data being probed *with* (this is the thing setup using the 3D widget).

arc_length is a measure of (b), and not (a). Since (b) doesn't change when the input is changed, arc_length isn't expected to change.

 OK, you have beat sense into me. Closing.
