Plotting 1D Data in VisIt

[ianabel]

I have some 1+1D data (x & time) from a simulation code that I would like to export for use in VisIt.
Currently the data is in NetCDF4/HDF5. I have tried exporting one timeslice to a vtu file, but that doesn't contain any 'curve' objects, only a scalar mesh object, which for the life of me I cannot persuade visit to plot as a simple graph (value of the scalar vs x, with a correct scale and no fake 'y' axis).

So, is there either an obvious data format I should be using for getting this data into visit so that curve objects can be generated at various time slices easily? Or is there an obvious way of plotting the curve from the vtu file?

This cannot depend on a custom plugin as I cannot expect my users to be compiling their own copy of visit.

@ianabel sorry you are having trouble with some simple curve data.

I think the best option is to store the data as x y pairs, line by line in an ascii file with .curve extension.

Example...

# TIME 3.321
# going_up
0 0
0.010101 0.000235273
0.020202 0.000829659
0.030303 0.00173407
0.040404 0.00292568
0.0505051 0.00438962
# flat
0 0.5
0.010101 0.5
0.020202 0.5
0.030303 0.5
0.040404 0.5
0.0505051 0.5
0.0606061 0.5

The # TIME line allows you to associate a simulation time for all curves in the file...thats for cases where the curves are all taken at some time during a simulation run.

The # <string> lines define a new curve name and the data following it.

This cannot depend on a custom plugin as I cannot expect my users to be compiling their own copy of visit.

BTW...using a custom plugin requires compiling only the plugin against an installed VisIt.

Oh, cool.

Thanks, completely forgot about plain text as an option. That seems wisest!
