### Getdist help

Thanks. Yes. The task3.paramnames files is in the samples file. But still the lables are not taken. Please also tell me how to change the plot bounds in a triangle plot.

Please email all your chain files and script if you think labels are not working.

Plot bounds are determined automatically, so usually you don't need to change them (and changing plot bounds is the wrong way to account for prior cuts - use .ranges for that). But you can use

Code: Select all

ax = g.subplots&#91;x,y&#93;
to get the subplot axis instance if you want to manually adjust the axes using standard matplotlib methods after making the triangle (or other) plot.

### Getdist help

I have observed that the GetDist GUI processes the chains without removing the burn-in. I could not find any option for setting the burn-in removal. Is it there?

If you are loading chains from a grid, as the Planck chain downloads, it should automatically determine whether to remove burn in for each chain.

For individual chains you can change burn in by changing the settings on the Options menu.
