>In each volcano plot figure I must have only 1 Experimental group vs Control?
Typically, yes, one axis is the log-ratio (exp/control), the other the log-P-value.
>I was thinking in a 3d volcano plot showing all 3 experimental groups at once.
Do you mean 2 experimental groups? One axis must be the log-Pvalue.
>Does anyone know some way to visualize differential express genes with more than 2 groups each figure?
A heatmap can be more informative, use fold-change or p-value for the color scale and you can separate by groups in one axis.
