Hello Guys! I need a help. i want make this heatmap: [heat] I’m trying with that code: Plots.heatmap(cor(Matrix(df[!,[:Age,:Balance, :Tenure,:NumOfProducts,:EstimatedSalary]])) ) [image] ** But how can i put the annotations of the correlation values and the columns names in the ticks? ** A…

Your efforts are commendable, but please note that this task should be less labor intensive. For example we could do: using DataFrames, Statistics, Plots # INPUT DATA df = DataFrame(Age=rand(4), Balance=rand(4), Tenure=rand(4), Salary=rand(4)) cols = [:Age, :Balance, :Tenure] # define subset M = …

[image] folleyz: But how can i put the annotations of the correlation values and the columns names in the ticks? One way is by searching discourse, which led me here .

I’m working all day on this and i found a solution, off course isn’t the best. 1 - First i created a dataframe with the correlations: a = DataFrame(cor(Matrix(df[!,[:Age,:Balance, :Tenure,:NumOfProducts, :EstimatedSalary]])), [:Age,:Balance, :Tenure,:NumOfProducts, :EstimatedSalary]) Age Bal…

Fyi, plot argument xrotation=90 rotates the xticks as per your model example.

[image] rafael.guerra: xrotation=90 Nice! thx for the tip. Below the final function to plot a corr heatmap: function corrheatmap(df::AbstractDataFrame ,colnames::Vector{Symbol}) a = DataFrame(cor(Matrix(df[!,colnames])), colnames) g = [] b = 1 for e in 1:length(colnames) for i in …

Wow! Nice @rafael.guerra ! Your solution its much better and clean, i’ll use that. Thx for participating!

If somebody arrives here looking for a solution with Makie. Below is an adaptation of @rafael.guerra ’s code: df = DataFrame(Age=rand(4), Balance=rand(4), Tenure=rand(4), Salary=rand(4)) cols = [:Age, :Balance, :Tenure] # define subset M = cor(Matrix(df[!,cols])) # correlation matrix (n,m) = …

Bump to add PlotlyJS solution in case anyone is interest. using Statistics using DataFrames using Printf using PlotlyJS function plot_cormap(df::AbstractDataFrame; colorscale="Viridis", fontcolor="#aabbcc", fontsize=14) m = cor(Matrix(df)) annotations = [ attr(text=@sprintf("%.2f",…
