Check the keyword `colorbar_ticks` and the [Supported Attributes · Plots](https://docs.juliaplots.org/dev/generated/supported/).  
This is only supported by the pyplot() backend.

However, with any other backend, it is easy to create your own color bar and decorations by treating it as a heatmap in a neighboring subplot.
