I am making a program that interpolates the points of some level curves, but when it comes to graphing, I am obtaining two individual graphs of the two level curves and not a single graph. I would like to get this output: Answer You need to declare plt.figure() only once, outside of the for loop. Inside the for loop you

Lineplot – plot a single legend for uneven number of subplots
I’m working on the following graph where I’d like to plot is single legend that applies to all, essentially this would be a small box where blue color line is AB=0 and green line is AB = 1. Moreover, I’m using plt.subplot(… since it is possible that might have to deal with uneven number of columns to plot. I tried

Matplotlib – Delete lines from a 3d quiver plot
I would like to graphically represent the time trend of a three-dimensional reference frame using Matplotlib and the quiver function. In an event, I simulated the data representing the reference frame through the definition of a 3×3 rotation matrix. Each time the event occurs, it should delete the previous reference frame and display the new one. Here is my code
Matplotlib axline is vertical when it should be at an angle…until I change the dates/times for the chart
I’m trying to draw an angled line on a chart with Matplotlib, but there are times when it just draws a vertical line, incorrectly. It appears to be a problem with the dates/times. It’s like there’s a minimum time required between points before it will plot correctly. Can anyone shed any light on this? Answer The reason why this happens
How can I find the mode (a number) of a kde histogram in python
I want to determine the X value that has the highest pick in the histogram. The code to print the histogram: Histogram and value wanted (in fact, I would like all 4): Answer You will need to retrieve the underlying x and y data for your lines using matplotlib methods. If you are using displot, as in your excerpt, then
only last curve with marker is plotted in for loop – how to plot all markers
I have created a list of markers in which each marker is used to show the max value of that curve. (4 curves -> 4 markers) Somehow I cannot get all the markers to appear in the plot. It seems only the first marker in the for loop is plotted. Answer You can greatly simplify your code, use idxmax directly
How to extend the color palette in matplotlib?
I coded the following function: And then the for-loop: As the for loop iterates over num_columns which has 40 variables, the standard palette only offers 10 colors. However, I want to have every variable its own color. Is there a way to code it also being flexible when it comes to the number of variables? Answer Matplotlib offers tab20, which
Matplotlib stacked histogram label
Here is my picture. I need to make label for those bars however every upper layer contains lower layer – so the label should containt grouped colors, i.e. blue – dataset 1, blue/orange – dataset 2, blue/orange/green – dataset 3 and finally blue/orange/green/purple – dataset 4. Is it plausible to make it? Thank you. enter image description here Answer The
How to plot colors based on cell values on a timestamp
I have a data which contains 16 columns, from which 1 column is “Time” column and other 15 columns are columns that represent colors. Data looks like this: What I need is to have a plot in which at every timestamp represent these 15 colors. The output should look like this: Any idea how to do this? Thanks!! Answer Instead
