Matplotlib plot barplots-stacked in a loop in different positions on x-axis
I have a list of dictionaries that have different keys and a different number of keys. I want to plot these elements in this list (dictionary), each element as a stacked bar plot. I could plot a single dictionary using the following code. I expected something like this But every bar is plotted in the same loc…
plotting a 3d graph of a regressor made with sklearn
I have been using this tutorial to learn decision tree learning, and am now trying to understand how it works with higher dimensional datasets. Currently my regressor predicts a Z value for an (x,y) pair that you pass to it. I want to use a 3d graph to visualise it, but I have struggled with the way regressor…
How to plot the fourth variable based on a given x, y and z coordinate framework

First column is my variable and three others are x, y and z coordinates, respectivly: The first column has some discrete values, e.g. it is 1 or 2 or 3. Now, using matplotlib or any other useful library like seaborn) I want to plot these values in a 3d
Python- compress lower end of y-axis in contourf plot
The issue I have a contourf plot I made with a pandas dataframe that plots some 2-dimensional value with time on the x-axis and vertical pressure level on the y-axis. The field, time, and pressure data I’m pulling is all from a netCDF file. I can plot it fine, but I’d like to scale the y-axis to b…

Also have all imported these libraries installed. I left %matplotlib inline as a comment be…

Transformation of coordinates between PyQt and matplotlib
I would like to show a context menu on the position of mouse click and then create a new line on that position in the graph. For that I need both the PyQt position and the graph data position. I thought that I could use the matplotlib transformation functions, but somehow when clicking the lower left and uppe…
