If I understood well, with heatmap from plots.jl you can change the colums with a string array

> Good afternoon! I can not get the heatmap plot in the Plots.jl package to do what I would like. If I do: using Plots backend(:plotly) p = heatmap([1,2,3,1,2,3,1,2,3],[1,1,1,2,2,2,3,3,3],[1,1,1,1,1,1,1,1,1]) gui(p) I get the result: [newplot] while I expect some kind of plot homogeneously filled with ones. (maybe from 0,5 to 3,5 in x and y?) What am I missing?
