Shared colorbar for all heatmap subplots

Suppose I have 3 heatmap plots of the form

(a.hvplot.heatmap(x=‘x’,y=‘y’,C=‘z’) + b.hvplot.heatmap(x=‘x’,y=‘y’,C=‘z’) + c.hvplot.heatmap(x=‘x’,y=‘y’,C=‘z’)).col(3)

Is there any way in which I can have one colorbar for all 3 subplots? Currently, setting colorbar=True for each plot has each subplot with its own colorbar. If I have colorbar=False for all but one, only one colorbar is shown, but does this mean that the values in all subplots will correspond to the same colorbar?
