Scatter plot does not work with group #328
Description
The following code is a MWE showing that scatter plots do not work for group. The second and third rows of the grid have the wrong scale and no data are displayed. Specifying xlims=(0,3) and ylims=(0,3) fixes the axes but no data are displayed.
using DataFrames, StatsPlots
title = [string("f1: ",i," ","f2: ",j) for i in 1:3 for j in 1:3]
title = reshape(title, 1, 9)
df = DataFrame(f1=repeat(1:3,inner=5),f2=repeat(1:3,inner=5),
z=repeat(1:3,outer=5), y=repeat(1:3,outer=5))
@df df scatter(:z, :y, group=(:f1,:f2), xlabel="z",
ylabel="y", xaxis=font(10), yaxis=font(10), grid=false, color=:grey,
leg=false, titlefont=font(10), title=title, layout=(3,3))
