Makie allows you to change almost every visual aspect of your plots via attributes. You can set attributes whenever you create an object, or you define a general style that is then used as the default by all following objects.
You can call
set_theme!(theme; kwargs...) to change the current default theme to
theme and override or add attributes given by
kwargs. You can also reset your changes by calling
set_theme!() without arguments.
Let's create a plot with the default theme:
using GLMakie function example_plot() f = Figure(resolution = (1000, 800)) for i in 1:2, j in 1:2 lines(f[i, j], cumsum(randn(1000))) end f end example_plot()
Now we define a theme which changes the default fontsize, activate it, and plot.
fontsize_theme = Theme(fontsize = 10) set_theme!(fontsize_theme) example_plot()
This theme will be active until we call
Because it can be tedious to remember to switch themes off which you need only temporarily, there's the function
with_theme(f, theme) which handles the resetting for you automatically, even if you encounter an error while running
with_theme(fontsize_theme) do example_plot() end
You can also pass additional keywords to add or override attributes in your theme:
with_theme(fontsize_theme, fontsize = 25) do example_plot() end
Every Layoutable such as
Colorbar, etc. can be themed by using its type name as a key in your theme.
Here is how you could define a simple ggplot-like style for your axes:
ggplot_theme = Theme( Axis = ( backgroundcolor = :gray90, leftspinevisible = false, rightspinevisible = false, bottomspinevisible = false, topspinevisible = false, xgridcolor = :white, ygridcolor = :white, ) ) with_theme(example_plot, ggplot_theme)
You can use the keys
colgap to change the default grid layout gaps.
