Linestyle in histplot

[romanovzky]

Hi there, how do I set the linestyle in histplot? I tried to pass it as a kwarg, but got

TypeError: errorbar() got multiple values for keyword argument 'linestyle'

I'm trying to plot histograms of the same variable produced through different methods and I'd like to be able to set the same colour, but different linestyles for each case.

Cheers

@romanovzky It sounds like you have histtype='errorbar' on, which uses errorbar underneath which doesn't have a ls kwarg. If you are expecting a "skyline" plot pass histtype='step'.

[romanovzky]

Thanks! That did the trick, but I can't then plot the errorbars. Is there a workround?

[andrzejnovak]

It depends how much control you want over the errorbars. The histtype='step' should plot some basic errorbars (cell 4 here), but if you want finer control you'll have to plot them in separate calls.

No, I can't seem to pass linestyle if I also pass yerr.

This doesn't work

    hep.histplot(
        h_v_sd,
        b,
        label="vac_SD",
        histtype="step",
        yerr=bkg_error_sd,
        density=True,
        color="k",
        **{"linestyle": "--"},
    )

Ah, I see it now. Yes, that's a bug, thanks for pointing that out.

Cool! Glad I helped out somehow. Cheers
