Text formatting

There are various options for formatting text contained in a plot, e.g., text added via pygmt.Figure.text, the plot title, labels of colorbars as well as Cartesian axes, and legend entries. It’s also possible to change the font as well as its color and size only for specific characters of a longer text. The supported fonts are listed at Supported Fonts. For an complete overview see Text Formatting.

# Change font color for specific letters of the word "PyGMT":
# blue for "P", yellow for "y", and red for "GMT"
fig.text(x=0, y=3, text="@;63/124/173;P@;;@;255/212/59;y@;;@;238/86/52;GMT@;;")

# Change font size and style for one single character, respectively
