How to I create a labelled scatter plot?
gadfly, julia, plot, scatter-plot
Solution
While @Oxinabox's answer works, the Gadfly way would be to use `Geom.label`, e.g.
using Gadfly
X = [1, 2, 2, 3, 3, 3, 4]
Y = [4, 4, 7, 7, 9, 1, 8]
Labels = ["bill", "susan", "megan", "eric", "fran", "alex", "fred"]
plot(x=X, y=Y, label=Labels, Geom.point, Geom.label)
There are a lot of benefits to this, including smart label placement to avoid label overlap, or you can pick from some easy-to-use rules like `:centered` or `below`. Plus it'll pick up font/font size from the theme.
Problem
I would like to draw a labelled scatterplot, like shown below, in Gadfly. (Source: http://support.sas.com/documentation/cdl/en/statug/63033/HTML/default/images/renda.png) How can I do this? The scatter plot is easy: ``` using Gadfly X = [1, 2, 2, 3, 3, 3, 4] Y = [4, 4, 7, 7, 9, 1, 8] Labels = ["bill", "susan", "megan", "eric", "fran", "alex", "fred"] plot(x=X, y=Y) ``` On Option is to use colours, but that isn't so great, cos the legend becomes huge (particularly in less trivial examples than this). ``` plot(x=X,y=Y, color=Labels) ```
