Hi,

I am trying to plot a heatmap with a colorbar, but I want to hide the axis lines and tick numbers, and add labels on top and bottom of the colorbar.

I could achieve this,

```plaintext
heatmap(rand(10,10),color=:RdBu,colorbar_title="ColorBar")

```

but don’t know how to plot something like this

Can anyone help?

The ` pyplot()` backend of `Plots` allows manual labeling of the color bar ticks:

```julia
using Measures, Plots; pyplot(dpi=300)
m = rand(10,10); lm = extrema(m)
heatmap(data, c=:RdBu, margin=10mm, clims=lm, colorbar_ticks=(lm, ["sink","source"]))

```
