3. Figure elements

The figure below shows the naming of figure elements in PyGMT.

• pygmt.Figure: having a number of plotting methods. Every new figure must start with the creation of a pygmt.Figure instance

• frame: setting plot or map boundaries (a combination of the single letters of WSNE, wsne, or lbtr), adding annotations, ticks, gridlines (afg), axis labels (+l), and title (+t), e.g., in pygmt.Figure.basemap. Detailed examples can be found at frame and axes attributes

• pygmt.Figure.plot: plotting lines or symbols based on pen or style parameters, respectively

• pygmt.Figure.text: plotting text strings whereby the font parameter adjusts fontsize, fontstyle, and color

• pygmt.Figure.legend: showing the naming of lines or symbols while the label is given in pygmt.Figure.plot

• pygmt.Figure.show: previewing the content added to the current figure instance
