The most popular tool for visualizations in Julia is the Gadfly package. We can add the Gadfly package (as described at the beginning of this chapter) using the add function:

Pkg.add("Gadfly")

From then on, we can make reference to the Gadfly package in any script using the following command:

using Gadfly

We can use the plot() function with standard defaults (no type arguments) to generate a scatterplot. For example, with the simple script:

using Gadfly
srand(111)
plot(x=rand(7), y=rand(7))

Note

We use the srand() function in all examples that use random results. The srand() function sets the random number seed value, so all results in this chapter are reproducible.

We generate a nice, clean ...
