[petsc-dev] comments on make streams

[Karl Rupp]

Hi,

nice work, Barry :-)

Is the plotting facility sufficiently reliable and available on target 
machines? The last thing we want to see is that 'make test' errors out 
because of a plotting failure.

I like it, it is a good compromise. Two more suggestions:
  - What about using a dashed line (no points) for the ideal scaling? 
The current blue points suggest that this is actual measured data.
  - Add a (small) legend on the top right, because we don't expect to 
see actual data points there? If the legend covers the ideal scaling 
curve, it's not an issue.

Best regards,
Karli
