In Datagraph 5.3, several new built-in color ramps were added as options to the scaler field command. These are standard color ramps, often used in scientific data visualization. In this video, you'll learn (1) about issues with the former rainbow color map, called a jet, (2) how to create a scalar field and use the new color ramp options, and (3) how you can create your own custom color ramps.
