Matplotlib Plotting
Learn all about Matplotlib Plotting in this comprehensive tutorial.
- •The plot() function is used to draw points (markers) in a diagram.
- •To plot only the markers, you can use shortcut string notation parameter 'o', which means 'rings'.
- •You can plot as many points as you like, just make sure you have the same number of points in both axis.
- •If we do not specify the points on the x-axis, they will get the default values 0, 1, 2, 3 etc.
Plotting x and y points
The plot() function is used to draw points (markers) in a diagram.
By default, the plot() function draws a line from point to point.
The function takes parameters for specifying points in the diagram.
Parameter 1 is an array containing the points on the x-axis.
Parameter 2 is an array containing the points on the y-axis.
If we need to plot a line from (1, 3) to (8, 10), we have to pass two arrays [1, 8] and [3, 10] to the plot function.
Plotting Without Line
To plot only the markers, you can use shortcut string notation parameter 'o', which means 'rings'.
Multiple Points
You can plot as many points as you like, just make sure you have the same number of points in both axis.
Default X-Points
If we do not specify the points on the x-axis, they will get the default values 0, 1, 2, 3 etc., depending on the length of the y-points.
So, if we take the same example as above, and leave out the x-points, the diagram will look like this:
