Hi,

I would love some feedback on this project where I was exploring some data visualization techniques. In particular I would like to know if it possible to somehow assign the Axes object returned when using the various pandas.DataFrame.plot methods to a specific matplotlib.figure object? To put it another way: can I create a figure object with subplots using:

fig, axarr = matplotlib.pyplot.subplots(3, 1)

and then assign my Axes object returned from say pandas.DataFrame.plot.hexbin() to one of the axes in axarr above?

Thanks!

Tom

hey @thaysom22

Your project is a great read. The sections and sub-sections provide a good workflow. :slight_smile: The plot sizing is really cool :ok_hand:

A summary or conclusion section at the end would help in making the project a complete analysis, though.

I didn’t quite get your question. Are you looking for something like this?

import matplotlib.pyplot as plt

y = [10, 20, 30, 15, 25, 5]
x = [1, 2, 3, 4, 5, 6]

fig, axarr = matplotlib.pyplot.subplots(3, 1, figsize=(10,5))
axarr[0].plot(x, y)
axarr[1].scatter(x, y)

If yes, this is one of the methods, there are other ways too. such as:

df = pd.DataFrame({"x":[1, 2, 3, 4, 5, 6], "y":[10, 20, 30, 15, 25, 5]})
df.plot(kind="bar", x="x", y ="y", ax = axarr[2])

You may go through the matplotlib documentation, projects from other students, or stack overflow posts as well to understand further.

Hope that helps.

Thanks Rucha.

I am realizing that it helps to include results in the introduction really helps readability.

I think the ax parameter is what I was looking for!

Thanks alot

Tom
