interpolate.gamma(gamma)
Given that interpolate is one of interpolateRgb, interpolateCubehelix or interpolateCubehelixLong, returns a new interpolator factory of the same type using the specified gamma. For example, to interpolate from purple to orange with a gamma of 2.2 in RGB space:
1 | var interpolator = d3.interpolateRgb.gamma(2.2)("purple", "orange"); |
