Yay finally posting again. Hopefully this video will help you get comfortable working through the matplotlib library. I'm going to post a follow up video with real-world examples (combining pandas with matplotlib) and different types of plots next week. I originally was going to include that in this one, but I thought the video was getting a bit too long.
In this video we walk through some of the basics of matplotlib. We start by making a simple line graph. We learn how to give the graph a title and label the x & y axis. We learn how to scale the graph by specifying the x & y tickmarks. After this, we restyle our line by passing in keyword arguments then do basically the same thing with a shorthand notation. We resize our graph and save it. Then we end with a simple bar chart.

Open up a terminal window and type
pip install matplotlib
pip install numpy
pip install pandas
Option 2:
Download anaconda which will contain all the packages we need. A video on how to do this is here: • Python Tutorial: Anaco...

I am really grateful for your tutorial videos, you cover all the must-know topics, your explanations are easy to understand and watching you make mistakes sometimes makes me comfortable as someone who's learning. You could totally roll out your own courses or work as a KZfaqr (or become a teacher) if you want to!

For those curious, you can use plt.annotate() to add the coordinates of markers to the graph. x = [your x coordinates list] y = [your y coordinates list] for i, j in zip(x, y): plt.annotate(f'({i}, {j})', (i, j), textcoords='offset points', xytext=(0, 5), ha='center') You can play around with the options, but this will add the coordinates centered slightly above the markers. If 5 seems too close, 10 is a better option.

Hi Keith! Thanks for this video! I'm working this tutorial on my Mac and I have come across some problems executing the codes here. On the first graph you made, I had trouble showing the graph size with the plt.figure, with a dpi of 300, line because the output didn't show an enlarged version of the graph. However, when I tried to run it, it the notebook showed this result . Second issue is with the Bar chart's hatches. I got good results with the slash and circles on the design but on the third one with the stars, I can't get past it. It only showed the same blue bar without a single stars at all. It was worse when I tried the for loop you did because it didn't show no patterns. Weird. Thanks fam!

Very helpful video. I tried the same process on my exercise but stacked where they said x and y must have same first dimension, but have shapes (30, 30) and (1,). I checked my x and y find they have the same dimension but I am not sure about z because it has 3D data. How can I solve it?

The xticks and ytics didn't work on Jupyter notebook but worked on Pycharm. Jupyter: TypeError: 'list' object is not callable PyCharm: does what it is supposed to do. Sometimes it is the other way around. And the command lines were identical (Ctrl+C Ctrl+V). This is why I prefer R: Python is far to "capricious" to be anywhere near reliable.
