Help to plot SEM and STD in one figure #75

Closed aleshins closed 5 years ago

aleshins commented 5 years ago

I have 3 variables X,Y, and IDX if I do the following:

g=gramm('x',X,'y',Y,'color',IDX);
g.stat_summary('type','sem','geom',{'point','errorbar'},'setylim',true,'width',0.5,'dodge',0.5);

I have a nice plot with SEM's. But i want to have the plot, where IDX == 1 has SEM error bars and IDX ==2 have STD error bars. Is it possible?

Hello,

stat_summary only does one type of summary at a time. For want you want to do, you would need to do it in two steps with different data selected using 'subset' with IDX, and using update(). I'm not 100% sure it would work for the different colors though...

Mixing different types of error bars in the same graph is probably not the best idea anyway ;)
