wtk_plot Struct Reference

Plot control struct.

Contains a pointer to the plot's containing window, and non-window information necessary for its operation. Structs of this type are created with wtk_plot_create().

Note

Structure fields are only internally accessible. Only pointers to these structures are needed externally.
