I’m using Plots with GR

Is it possible to make empty plot with colorbar?

I try:

```julia
plot(;colorbar=true, clims = (-0.05, 0.05),c = cg, zcolor = 1)

```

colorbar - not displayed.

Is it possible to change width of colorbar?

I try to do something like this:

But now it looks very bad.

I would use a layout and instead of the colorbar I would plot a heatmap with only the y-axis labels. See [this solution](https://discourse.julialang.org/t/setting-the-foreground-color-of-colorbar-tick-marks/122911/4).

Unrelated to the previous answer, for this you need to plot some dummy data (ex: NaN), and use `framestyle=:none`

```julia
plot([1], [NaN]; colorbar=true, clims=(-0.05, 0.05), c=cgrad([:blue, :red]), framestyle=:none)

```
