Hi all,

I have a group of contour subplots (see below). I would like to reduce the scales to one, rather than have redundant scales. I am trying to figure out how to (1) remove white space in color scale for missing values, and (2) suppress the color scales on the subplots in the top row. How can this be achieved?

```
using Plots
config = (
xaxis = font(8),
yaxis = font(8),
titlefontsize = 10,
clims = (10,250)
)
x = 1:0.5:20
y = 1:0.5:10
f(x, y, β) = begin
(β * x + y ^ 2) * abs(sin(x) + cos(y))
end
X = repeat(reshape(x, 1, :), length(y), 1)
Y = repeat(y, 1, length(x))
Z = map((x,y) -> f(x, y, 2.5), X, Y)
p1 = contour(x, y, Z,
fill = true, xlabel="x", ylabel="y",
title = "a"; config...)
Z = map((x,y) -> f(x, y, .8), X, Y)
p2 = contour(x, y, Z,
fill = true, xlabel="x", ylabel="y",
title = "b"; config...)
Z = map((x,y) -> f(x, y, .1), X, Y)
p3 = contour(x, y, Z,
fill = true, xlabel="x", ylabel="y",
title = "c"; config...)
layout = @layout [a b; c]
plot(p1, p2, p3; layout, dpi=300, size=(340,300))
```
