3.25.54.4 cubehelix

The "cubehelix" option defines a family of palettes in which color (hue) varies along the standard color wheel while at the same time the net intensity increases monotonically as the gray value goes from 0 to 1.

`start` defines the starting point along the color wheel in radians. `cycles` defines how many color wheel cycles span the palette range. Larger values of `saturation` produce more saturated color; saturation > 1 may lead to clipping of the individual RGB components and to intensity becoming non-monotonic. The palette is also affected by `set palette gamma`. The default values are

           set palette cubehelix start 0.5 cycles -1.5 saturation 1
           set palette gamma 1.5
