Hi Guys trying out the PoltlyJS package. I wanted to plot the classic iris data set. I was trying to build my own pairplot. However, plotlyJS gives some strange behavior. When I subplot the histogram it no longer overlays and the binning appears to change as the height of the histogram changes.
using PlotlyJS
using CSV
using DataFrames
col_names = ["SepalLength", "SepalWidth", "PetalLength", "PetalWidth", "Class"]
iris = CSV.read("iris.csv"; header = col_names, normalizenames = true)
iris = groupby(iris, :Class)
gp_1 = iris[1]
gp_2 = iris[2][1,5]
gp_3 = iris[3][1,5]
function histo(df::GroupedDataFrame, i::Int)
data = typeof(histogram())[]
for k in 1:length(df)
x = df[k][!,i]
fields = Dict{Symbol,Any}(
:type => "histogram",
:x => x,
:opacity => 0.5,
:nbinsx => 10
)
trace = GenericTrace("histogram", fields)
push!(data, trace )
end
return data
end
function scatt(df::GroupedDataFrame, i::Int, j::Int)
data = typeof(scatter())[]
col = i
row = j
for k in 1:length(df)
y = df[k][!,i]
x = df[k][!,j]
trace = scatter(x=x, y=y; mode="markers")
push!(data, trace)
end
return data
end
layout = Layout(barmode="overlay")
p1 = plot(histo(iris, 1), layout )
p2 = plot(scatt(iris,2,1))
[p1 p2]
If just plot the histogram you get
If you stack subplot it via [p1 p2] the you get
Any help would be appriciated.
