contourf
contourf(xs, ys, zs; kwargs...)
Plots a filled contour of the height information in
zs
at horizontal grid positions
xs
and vertical grid positions
ys
.
The attribute
levels
can be either
-
an
Intthat produces n equally wide levels or bands -
an
AbstractVector{<:Real}that lists n consecutive edges from low to high, which result in n-1 levels or bands
You can also set the
mode
attribute to
:relative
. In this mode you specify edges by the fraction between minimum and maximum value of
zs
. This can be used for example to draw bands for the upper 90% while excluding the lower 10% with
levels = 0.1:0.1:1.0, mode = :relative
.
In :normal mode, if you want to show a band from
-Inf
to the low edge, set
extendlow
to
:auto
for the same color as the first level, or specify a different color (default
nothing
means no extended band) If you want to show a band from the high edge to
Inf
, set
extendhigh
to
:auto
for the same color as the last level, or specify a different color (default
nothing
means no extended band)

Relative mode
Sometimes it's beneficial to drop one part of the range of values, usually towards the outer boundary. Rather than specifying the levels to include manually, you can set the
mode
attribute to
:relative
and specify the levels from 0 to 1, relative to the current minimum and maximum value.
