[Paraview] 3.8 RC1 regression in line chart ?

[Richard GRENON]

Hello, here is me again.

I have found some kind of regression with the line charts (XY plots) in 
PV 3.8 RC1:
First, loading a very simple csv file with three columns (named P, R and 
T), then using filter "PlotData":

1. the XY windows comes with the top "VARIABLE" box unchecked and all my 
variables (P, V, T) boxes checked in the Line Series panel of the 
Display tab, but the XY window remains empty until I check the top 
"VARIABLE" box. The default X axis is the Row ID. OK.

2. Now I want to use one of my three data arrays as the X axis: I select 
the radio-button and the first variable P is selected by default on the 
list-box. OK, this is the variable I want on the X axis, but I get many 
error messages because "No X column is set (index 0)". I have to select 
another X axis variable, then to come again on the P variable. No more 
error, but the X axis remains scaled with the Row ID values! I have to 
uncheck a variable in the line series panel and to check it again to 
obtain the correct P values on the X axis. Finally I get my three curves 
and I can change the X axis variable as I want.

3. All variables are scaled by default with the bottom-left axis system 
and I want to scale one of the variables on the right axis. I select one 
variable in the Line series panel and I try to change the default 
bottom-left Chart Axes for bottom-right or top-right axis system. 
Nothing happens: the top and right axis don't appear and all variables 
remain scaled on the bottom-left axis system. I can change some 
attributes of the variable (Line thickness, Line Style, Marker), but not 
the Chart Axes, although it was possible to change the Chart Axes with 
PV 3.6.2.

I attach the very small csv file that I used for my tests.

Regards.

Richard
