Plotting our first graph
We will start with a simple line graph of a curve of squares, that is, y = x2.
Loading data for plotting
To visualize data, we should start with "having" some data. While we assume you have some nice data on hand to show, we will briefly show you how to load it in Python for plotting.
Data structures
There are several common data structures we will keep coming across.
List
List is a basic Python data type for storing a collection of values. A list is created by putting element values inside a square bracket. To reuse our list, we can give it a name and store it like this:
evens = [2,4,6,8,10]
When we want to get a series in a greater range, for instance, to get more data points for our curve of squares to make it smoother, we may use the Python range() function:
evens = range(2,102,2)
This command will give us all even numbers from 2 to 100 (both inclusive) and store it in a list named evens.
Numpy array
Very often, we deal with more complex data. If you need a matrix with multiple...
