brewproof

Prefix command to create color sight impairment proofs of a graph.

brewproof – is a program to generate a proof copy of a graph to simulate how the image would be viewed by individuals with achromatopsia, protanopia, deuteranopia, and tritanopia.

Syntax

brewproof, scheme(brewscheme scheme file): graph command

Description

brewproof is used to simulate the appearance of the specified graph as seen if the viewer suffered from achromatopsia, protanopia, deuteranopia, or tritanopia. This is a prefix type command that wraps the user-specified graph file to generate separate simulated graphs as well as a proof copy with all four of the color impaired versions of the graph on a single image.

Examples

Ex 1.

Proof a graph with ggplot2 styled aesthetics.

// Load the auto data set
sysuse auto.dta, clear

// Proof the examples used in other help files
brewproof, scheme(ggtest2) : tw lowess mpg weight             ||     ///   
                             scatter mpg weight if rep78 == 1 ||     ///   
                             scatter mpg weight if rep78 == 2 ||     ///   
                             scatter mpg weight if rep78 == 3 ||     ///   
                             scatter mpg weight if rep78 == 4 ||     ///   
                             scatter mpg weight if rep78 == 5,       ///   
                             legend(order(2 "1978 Repair Record = 1" ///   
                             3 "1978 Repair Record = 2"              ///   
                             4 "1978 Repair Record = 3"              ///   
                             5 "1978 Repair Record = 4"              ///   
                             6 "1978 Repair Record = 5")) 

The baseline/original graph specified by the user (this is the same graph illustrated on the brewtheme page.).

Achromatopsia simulated appearance.

Protanopia simulated appearance.

Deuteranopia simulated appearance.

Tritanopia simulated appearance.

The proof graph with all four forms of colorblind simulated appearances in a single image.

// Loop over the schemes
foreach scheme in onecolorex1 onecolorex2 ggplot2ex1          ///
