## Matplotlib Tutorial 1 – Introduction and Line

[ad_1]

Welcome to a Matplotlib with Python 3+ tutorial series. In this series, we’re going to be covering most aspects to the Matplotlib data visualization module. Matplotlib is capable of creating most kinds of charts, like line graphs, scatter plots, bar charts, pie charts, stack plots, 3D graphs, and geographic map graphs.

First, in order to actually use Matplotlib, we’re going to need it!

If you have a later version of Python installed, you should be able to open cmd.exe/terminal and then run:

pip install matplotlib

Note: You may need to do C:/Python34/Scripts/pip install matplotlib if the above shorter version doesn’t work.

I've made a 3D scatter plot by following your tutorial, but now I'm looking for that when I put my mouse on a certain data point in the plot, it could select that point and show me the exact coordinates of that point…. How can I achieve this….

Nice video.

I have an article about Python data visualization with Maptlotlib in Jupyter Notebook for Absolutely Beginner.
You can check this link

What GUI is being used here? Jupyterlab? I'm asking because in Jupyter Notebooks and JupyterLab, my plot doesn't pop up in a separate window with the buttons on the bottom.

I'm using Jupyter Notebook and in the end the graph shows, but it doesn't show icons nor can I move the graph.

You are plotting two lists(which are already populated).
can we plot the points in the real time i.e., without creating a list?

Hey I was going to ask you, do you have any good videos on Python using a mac?

Stop now. Find another tutorial. Later on, when you go through pulling data from the internet, you will run into trouble because those sites are gone and the code has to be changed. Just save yourself the trouble.

Don't forget to turn your data into numbers (int or float) or you will get really confusing results if they are strings

The longer path also does not work, I get a syntax error (windows 10, absolute beginner). Any advice?

Hello , please can you help me .I'm really stuck. I drew 3 curves in the same figure using Pycharm but the scale of graduations for the y-axis is really catastrophic. In fact for one of the curves the values are very small whereas for the other curve the values are very large so that the curve whose values are very small is almost not displayed. please help .
This is the code:

import numpy as np
c1,c2,c3=np.array([0,400],dtype=float),np.array([300,12500],dtype=float),np.array([20,45],dtype=float)
mb1,mb2,mb3=np.array([0,18],dtype=float),np.array([0,12.2],dtype=float),np.array([0,1.4],dtype=float)
import matplotlib.pyplot as plt
plt.plot(mb1,c1,'s-',markerfacecolor='white',label="Process 1 ")
plt.plot(mb2,c2,'s-',markerfacecolor='white',label="Process 2 ")
plt.plot(mb3,c3,'s-',markerfacecolor='white',label="Process 3")
plt.yticks(c1, c1, color='k')
plt.xticks(mb1, mb1, color='k')
#ajouter les limites des axes
plt.xlim(0.4,20)
plt.ylim(20,12500)
plt.grid()
plt.legend()
plt.show()
plt.savefig('image.png')

One thing is bad about programing is you have to update course time to time . Technology is growing so fast
