I am trying to generate a horizontal chart for the dataset I have. I am trying a get a chart that looks like this using Python.
This is how my dataset looks like:

When I use plt.plot, I get something like this:

I want to plot a color bar like the following picture:
Like shown in the picture, the color bar will be a list of RGB values with the corresponding class names for each. How do I do this in Python, especially in Matplotlib? I have both the RGB values and the class names.
This is supposed to be a common task in image segmentation, but I cannot come up with a direct solution. Thank you for your help.

If what you want is to make the background a grid, just like on paper, you can use the matplotlib.pyplot.grid() method. You can find more information about it here:

Given some data frame we can easily plot the histogram for each column in a notebook like so:
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
df.hist()
But instead of having one plot per column is it possible to plot it in one plot the same way tensorboard does it?
Is a 3D histogram the best we can do? Maybe using something different then matplotlib?

I have imported an Excel file and want to plot a 2D graph by using data from that file.
I have used matplotlib to plot graph by using
df.plot("Col1","Col2") but its is not showing X-labels in the graph which should be text(Col1)
What changes should I apply to Code()?
According to pandas docs your code is correct. Perhaps you can try another method of showing the x-label in order to see where the problem comes from. You can try the following
ax = df.plot() # retrieve the matplotlib Axes object
ax.xlabel("Col1") # set the x-label
ax.ylabel("Col2") # set the y-label
See this docpage

I am attempting to plot a graph similar to the one attached below. The y-axis should be aligned and the x-axis scale and name should be same. Also, I want the dotted line as shown in the figure.
I tried combining two different graphs but that is certainly not a good way to solve this.
Sorry for the poor quality picture but the important points are mentioned.
Look into the matplotlib docs. I think you might be looking to use plt.subplots with the sharex argument.
