I have a two boxplotes But I want to place them in one graph to compare them. Have you any advice to solve this problem? Thanks! Answer Use return_type=’axes’ to get a1.boxplot to return a matplotlib Axes object. Then pass that axes to the second call to boxplot using ax=ax. This will cause both b…

I am using the matplotlib scatterplot function to create the appearance of handles on vertical lines to delineate certain parts of a graph. However, in order to make them look correct, I need to be able to align the scatter plot marker to the left (for the left line / delineator) and / or right (for the right…
pyplot combine multiple line labels in legend
I have data that results in multiple lines being plotted, I want to give these lines a single label in my legend. I think this can be better demonstrated using the example below, As you can see at Out[23] the plot resulted in 5 distinct lines. The resulting plot looks like this Is there any way that I can tel…

I am using a Compound screen made up of 4 by 4 monitors with small (but nonzero) bevel — the gap between the screens. This gap is black…
Move and resize legends-box in matplotlib
I’m creating plots using Matplotlib that I save as SVG, export to .pdf + .pdf_tex using Inkscape, and include the .pdf_tex-file in a LaTeX document. This means that I can input LaTeX-commands in titles, legends etc., giving an image like this which renders like this when I use it in my LaTeX document. N…
Plot histogram with colors taken from colormap
I want to plot a simple 1D histogram where the bars should follow the color-coding of a given colormap. Here’s an MWE: which outputs this: Instead of the color being green for the entire histogram, I’d like the columns to follow a color-coding given by the colormap defined in cm and the values of …
How to have clusters of stacked bars
So here is how my data set looks like : I want to have stacked bar plot for each dataframe but since they have same index, I’d like to have 2 stacked bars per index. I’ve tried to plot both on the same axes : But it overlaps. Then I tried to concat the two dataset first : but here
