This means that the color bar can configured there, for example it can be hidden: You can also configure the title, size, placement and tick marks and labels on a color bar: This is the same example as the Parallel Coordinates plot above, with customized tick text for species: You can customize text on a logarithmic color bar to make it more readable: The following example uses the marker.cmid attribute to set the mid-point of the color domain by scaling 'cmin' and/or 'cmax' to be equidistant to this point. From the output, we can see that instead of a color scale that shows up the value range, discrete color representation is showing results with exact values. Fork 604. The discrete colorscale should be defined as follows: find the max value for z, let us say that it is 125: map the interval [0, max_val] to [0,1] by t--> t/max_val. Here are all the built-in sequential scales in the 'RColorBrewer' package: A collection of predefined diverging color scales is provided in the 'RColorBrewer' package.
