Interactive Visualization and Plotting with Julia
By :

This section will teach you to select and create colors and color schemes for Plots
and Makie. Both packages base their color utilities on the Colors
and ColorSchemes
packages. So, Plots
and Makie accept any Colorant
or named color that the Colors
package can parse as Colorant
. In particular, the most popular way to set colors in those packages is by using a Symbol
or String
object containing the color name. For example, :red
and "red"
are valid indications to select the color red. You will find the list of named colors in the Colors
package documentation at https://juliagraphics.github.io/Colors.jl/stable/namedcolors/. The Colors
package supports CSS/SVG and X11 color names – it uses only the X11 names that do not clash with the CSS/SVG ones.
In the case of the Plots
package, we can set a color using false
or nothing
to assign a fully transparent color. The Plots
package also re-exports the Colorant
type and the colorant
string macro from Colors...
