This is the way to see more tables or graphs in the same window with matplotlilb, the module for python to see data. In this case we take our code to analyse covid data about Italy, France and South Korea together. We have seen how to do it in other posts. Here I abstracted a little bit the code so that is easy to change data from one Country to another. I used subplot<\/a> instead of tiledlayout<\/a> to use it in this interactive shell on the webpage. Go to the link to get more informations about it. For what I experimented you just have to give subplot the number of tables you want in the same window as first argument and then 1 and then the number of order of the graph (1 for the first, 2 for the second ecc.).<\/p>\n

Here is the code to embed it into a web page and run it from the web page itself with this codecamp shell. After the code, you will find the shell itself to see how it works.<\/p>\n
