Enumeration Type Documentation

enum PlotAxis

Axis specification for plots.

PLOT_AXIS_X1 is the bottom axis, PLOT_AXIS_Y1 is the left side axis, PLOT_AXIS_X2 is the top axis, PLOT_AXIS_Y2 is the right side axis and PLOT_AXIS_Z is the depth axis for three dimensional plots or colormap plots.

Enumerator:

PLOT_AXIS_X1
PLOT_AXIS_Y1
PLOT_AXIS_X2
PLOT_AXIS_Y2
PLOT_AXIS_Z

enum PlotFixedMode

Fixed aspect ratio setting for frame.

Default mode is PLOT_FIXED_ASPECT_DISABLED, which means that the frame axes are independent of each other. The mode PLOT_FIXED_ASPECT_EXTEND_RANGE has fixed aspect ratio, which is made by preserving the plot margins and extending the range of the smaller axis. The mode PLOT_FIXED_ASPECT_INCREASE_MARGIN fixes the aspect ratio by increasing the margin of the larger axis.

PLOT_FIXED_ASPECT_DISABLED
PLOT_FIXED_ASPECT_EXTEND_RANGE
PLOT_FIXED_ASPECT_INCREASE_MARGIN
