Dear all,
When I output the 3-D scatter plot I find the dots are very sparse. (Chains are converged and there are sufficient chain elements.) How can I increase the dots to refine the plot?
Many thanks.
Best,

Re: CosmoMC:3D scatter plot
By default it uses at most 2000 points. You can override this by using e.g. in distparams.ini
make_single_samples = T
single_thin = 1
which will use as many samples as available (no thinning).
However you can be converged for mean values without having enough samples to make good scatter plots. Try running longer to get more samples - e.g. use a more stringent test of limit convergence in params.ini:
MPI_Check_Limit_Converge = T
MPI_Limit_Converge = 0.025
MPI_Limit_Converge_Err = 0.3
make_single_samples = T
single_thin = 1
which will use as many samples as available (no thinning).
