It is possible to create a volcano plot without significant genes? #50

Hi! I have read through #22, #31 and #39 which are similar, as they show the error AssertionError: either significant or non-significant genes are missing; try to change lfc_thr or pv_thr to include both significant and non-significant genes, but I can't find a way to plot a volcano plot when there are no significant genes. I am using these plots as an exploratory analysis of several datasets and it would be very useful for me to see cases where there are no significant genes.

Thanks!

Yes, it could be possible. Change the threshold of log fold change and p values just to make a few genes at a significant level (based on your criteria). You can also keep the same color using a color parameter.
