Seaborn Lattice Plot/ Relationship Plot with Double Y Axis - python

I know how to make a lattice plot (https://seaborn.pydata.org/tutorial/axis_grids.html) or relationship plot (https://seaborn.pydata.org/generated/seaborn.relplot.html#seaborn.relplot).
However, what if each inidivdual plot needs to be a plot with 2 Y-axis? And within each plot, there are 4 lines, 3 lines using the left Y-axis and 1 line using the right Y-axis, something like the figure below:
So instead of the 4 scatter plots such as the figure below from the seaborn documentation, I need 4 of my double Y-axis figures... ... I am think of using the FacetGrid function, but it seems like my argument must be an sns plot that can be written in one line only, and I cannot use the matplotlib twinx() function.
Any help is greatly appreciated, thank you!

Show plots side by side

I have functions that produces plots,
And i used it three time with different values to give me three plots.
My question is that i want to put the plots side by side horizontally to be able to compare them.
As doing the following show every plot after the other vertically.
make_plot(twiss)
make_plot(twiss_error)
make_plot(twiss_corrected)
If you are using matplotlib perhaps use subplots:
https://matplotlib.org/3.5.0/api/_as_gen/matplotlib.pyplot.subplots.html
import matplotlib.pyplot as plt
fig, ax = plt.subplots (1,2)
you can access subplots by index as in
ax[0]
in your code.
Hope that this helps.

Using plot and scatter on same figure with different colors but even if I plot first, the scatter still show up UNDER the plot

I am plotting a distribution of variables that are outputs from two different versions of a program. They look very similar (this is great because they should!) and I am showing their ratio in the same figure but on a different axis. My goal is to show the ratio as a scatter plot but with a horizontal line at y=1.0 to show 100% agreement. The issue I am having is even if I plot the line first and then the scatter, my scatter points still show underneath the line plot. (Please see the image linked below.) You can see the scatter in black underneath the line plot in red, even though I call the plot function first. Any recommendations? Thank you!

Superimposing some plots with a txt file

`I am trying to reproduce the attached figure step by step. My problem was that how can i plot colorbar in above figure by my data. My data is a cosmological data and it has 7 columns totally with many raw. My main goal is reproducing the present figure step by step. You can see that there are three different plots which are interpolated each other. Firstly, i tried to plot small colorful lines in the body of figure by using two columns of data. I did it by scatter plots and then i needed to reproduce the colorbar part of figure. But, it was not possible at the first attempt. Because, the colorbar points was not a part of data. Then, i obtained the values of colorbar by some calculations and added them as additional columns to data. Now, i could you the simple colorbar function to do colorbar part. And i got it. For the next step, i need to turn small curved lines to dark solid lines.
How can I do plots in matplotlib?
import numpy as np
import scipy as sp
import matplotlib.pyplot as plt
data1 = np.loadtxt("bei_predic.txt", unpack=True)
B = np.log10(data1[3]/(4.*(data1[2])))
R = np.vstack((data1,B))
R = np.transpose(R)
D = R[~np.isnan(R).any(axis=1)]
A = plt.scatter(D[:,3],D[:,2], c=D[:,8])
cbar= plt.colorbar()
cbar.set_label("file", labelpad=+1)
plt.show()
If you could start off by telling us a little bit about the data that you are using that would be great. In order to plot the figure that you want, we must first load the data into some variables. Have you managed to do this?
Check out this example in which the author plots multicolored lines for some guidance.

How to plot independent graphs next to each other using seaborn?

my problem is that I could only find answers for plots sharing the same y-axis units.
My graphs are defined as follows:
#Plot1
sns.set_style("white")
sns.catplot(y="Reaction_cd_positive", x="Flux_cd_positive",
kind="bar",height=4, data=CDP,aspect=1.5)
#Plot2
sns.catplot(y="Reaction_cd_negative",x="Flux_cd_negative",
kind="bar",height=4, data=CDN, aspect=1.5)
Thank you in advance!
Ok, let me translate this. You are using seaborn in a jupyter notebook. You want 2 barplots next to each other within the same figure, instead of two individual figures. Since catplot produces a figure by itself, there are two options.
Create a single catplot with two subplots. To this end you would need to concatenate your two DataFrames into a single one, then use the col argument to split the data into the two subplots.
Create a subplot grid with matplotlib first, then plot a barplot into each of the subplots. This is shown in this question.

How to return a histogram and a scatterplot using matplot lib?

I need to return both a histogram and a scatterplot in one function using matplotlib, but when I try to create the histogram after creating the scatterplot, it appears that the scatterplot gets overridden. Just wondering if anyone has any advice on this issue? Is there a way to return two plots at once if they share an x-axis?
For instance, there is paragraph included in this link http://matplotlib.org/users/pyplot_tutorial.html about how to have 2 subplots. But I'm not sure how to do that with plt.hist() and plt.plot().
Since the histogram fills the bars it is probably better to do it first then the scatter plot.
