Feature request: Parallel Coordinates Plot

[ngphuoc]

Could you please add graph_objs.Parcoords as in plotly.graph_objs.Parcoords in python https://plot.ly/python/parallel-coordinates-plot/? It is a very useful plot for high dimensional data.

Ahh yes, sorry. I believe I did not keep the trace list up to date. Will do

[sglyon]

Actually, I just checked and I think this is already available with the function parcoords

Can you please verify?

That would be great. I tried a plot similar to the python one. I get an error below, could you help me correct it?

parcoords(;line = attr(color = "blue"),
        dimensions = [
            attr(range = [1,5],
                 constraintrange = [1,2],
                 label = "A", values = [1,4]),
            attr(range = [1.5,5],
                 tickvals = [1.5,3,4.5],
                 label = "B", values = [3,1.5]),
            attr(range = [1,5],
                 tickvals = [1,2,4,5],
                 label = "C", values = [2,4],
                 ticktext = ["text 1", "text 2", "text 3", "text 4"]),
            attr(range = [1,5],
                 label = "D", values = [4,2])
        ]) 
#  parcoords with fields dimensions, line, and type
plot(parcoords)

Ahh I think you are not storing your parcoords trace.

Try something like trace = parcoords(YOUR_CODE_HERE)

And then plot(trace)

Silly me, it works! Many thanks.
