Function createPiecewiseConstantColorMap

createPiecewiseConstantColorMap(levelsToColorsMapping): ColorMap
Create a piecewise constant color map. Unlike a gradient color map, no colors are interpolated in a piecewise constant map.

The example shows a ColorMap with 3 levels and 2 colors. The levels are mapped to colors as follows (level -> color):
- ]-inf, 100[ -> Black
- [100, 200[ -> Black
- [200, 300[ -> Green
- [300, +inf[ -> Green
Parameters
- levelsToColorsMapping: (string | number)[]
  An array with alternating level, color values in it. Levels should be Numbers. Colors are represented as RIA Colors. The first element is a level. Elements are expected to be sorted in ascending level order.
```
var piecewiseConstantColorMap = ColorMap.createPiecewiseConstantColorMap(
   [100, "rgba(0, 0, 0, 1.0)", 200, "rgba(0, 255, 0, 1.0)", 300]);
```
Returns ColorMap
