Abstract

In this presentation, I will present two new Stata commands to produce heat plots. Generally speaking, a heat plot is a graph in which one of the dimensions of the data is visualized using a color gradient. One example of such a plot is a two-dimensional histogram in which the frequencies of combinations of binned X and Y are displayed as rectangular (or hexagonal) fields using a color gradient. Another example is a plot of a trivariate distribution where the color gradient is used to visualize the (average) value of Z within bins of X and Y. Yet another example is a plot that displays the contents of a matrix, say, a correlation matrix or a spacial weights matrix, using a color gradient. The two commands I will present are called heatplot and hexplot.
