Hi,

I’m using the hist function in the CairoMakie package to create a layout of histograms. The histograms show the distribution of means from bootstrapping. I also have the theoretical mean values which I would like to plot on top of the histograms. Is there any way to do this on Julia?

Probably `vlines` is what you want

Actually it worked with hist!() after the previous hist() plot, thanks anyways.
