Thanks for more info.
I do in fact have "Time" for one of my plots so that is easy to
achieve. I just had to correctly set the name of the column from "Time
Values" to "Time" and that should work. The other plots probably are
more difficult at this point. I have Stress/Strain data where I need
the Stress on the x-axis and strain on the y-axis. I do not think I am
understanding how to set some value on the vtkTable class that when
finally passed over to the GUI layer will set the some arbitrary
column as the x-axis. I thought the proxy stuff was all done on the
GUI side of things? I guess I need just a bit more hand holding.

Sorry, yes, I was in VTK world. There are a few column names with
special meanings to ParaView that are hard coded in the proxy. You can
get at the chart object if you wish to manipulate it directly, but you
should be able to achieve everything you need to through the proxies.

I think by default it will plot a line for each column in the
table. It
will use the cell value as the Y value, and the row index as the X
value.
To change the behavior, you have to change two representation
properties:
rep.UseIndexForXAxis = 0
rep.XArrayName = 'foo'
This will plot all all the columns, except use the "foo" column as
the X
values. That means the line for the "foo" column is still
displayed, and it
will be a diagonal line.
I just looked, and Paraview has one cheat hard coded- if there is a
column
named "Time" or "arc_length" then it will be used automatically for
the X
axis.

Thanks for the idea. I was trying to figure out the flow from
reading the
data into displaying the data hoping to reveal some sort of
default or
something. I was going to generate some fake CSV data and see how
that
reader does things hoping the CSV reader takes the first column as
the
x-axis.

Hi Mike,
I'm not up to speed with the current chart api so I can't answer
your
question... but maybe you could try doing it in the gui with
python trace
enabled, then translate the generated python code into c++ for
your plugin?
Customizing the chart should be a matter of setting properties
on the
representation and view, the data object itself doesn't have much
say.

I have some XY data that I would like to plot in ParaView. I
currently
have a plugin that reads the data from our HDF5 file and into
vtkTable
objects. Along the lines of a "Line Chart 101" question how do I
programmatically set the x-axis and y-axis columns?
Thanks
