Moving Colorbar in Matplotlib Backend

pgierz · April 27, 2020, 8:21am

Hello,

I’m finializing figures for a publication and need to now produce SVG output. Probably it’s better to switch to the matplotlib backend for this (or am I mistaken here?)

I’m trying to re-apply options from bokeh to matplotlib (here, an automatic translator would be fantastic, but I realize this is a big ask). I’m trying to move colorbars from the side to the bottom, but this doesn’t seem to be working.

Any hints?

Cheers,
Paul

I don’t think horizontal colorbars are supported in holoviews as their positions are semi-hardcoded / computed to be on the right

github.com

holoviz/holoviews/blob/master/holoviews/plotting/mpl/element.py#L763-L816


def _draw_colorbar(self, element=None, dimension=None, redraw=True):
    if element is None:
        element = self.hmap.last
    artist = self.handles.get('artist', None)
    fig = self.handles['fig']
    axis = self.handles['axis']
    ax_colorbars, position = ColorbarPlot._colorbars.get(id(axis), ([], None))
    specs = [spec[:2] for _, _, spec, _ in ax_colorbars]
    spec = util.get_spec(element)


    if position is None or not redraw:
        if redraw:
            fig.canvas.draw()
        bbox = axis.get_position()
        l, b, w, h = bbox.x0, bbox.y0, bbox.width, bbox.height
    else:
        l, b, w, h = position


    # Get colorbar label
    if isinstance(dimension, dim):

I drafted something like that a while ago, check out

but of course your mileage may vary. Those are just scripts for my own use that I adjust as I go, they are probably not comprehensive. But maybe they’ll give you a starting point.
