Matplotlib is an amazing visualization library in Python for 2D plots of arrays. Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack. It was introduced by John Hunter in the year 2003.
One of the greatest benefits of visualization is that it allows us visual access to huge amounts of data in easily digestible visuals. Matplotlib consists of several plots like line, bar, scatter, histogram etc.
Ticks are the values used to show specific points on the coordinate axis. It can be a number or a string. Whenever we plot a graph, the axes adjust and take the default ticks. Matplotlib’s default ticks are generally sufficient in common situations but are in no way optimal for every plot. Here, we will see how to customize these ticks as per our need.
Parameter Value Use axis x, y, both Tells which axis to operate reset True, False If True, set all parameters to default direction in, out, inout Puts the ticks inside or outside or both length Float Sets tick’s length width Float Sets tick’s width rotation Float Rotates ticks wrt the axis colors Color Changes tick color pad Float Distance in points between tick and label
Example #1: Default plot
Example #2: Playing with the ticks
Suppose we don’t want to display the values of ticks or want our ticks to be tilted or want any other customization. We can do it this way.
Example #3: Changing the values of ticks.
In the first example, the x-axis and y-axis were divided by the value of 10 and 2 respectively. Let’s make it 5 and 1.
The main difference from the 1st example is :
plt.xticks(np.arange(0, 51, 5))
plt.yticks(np.arange(0, 11, 1))
Changing the values in np.arange will change the range of ticks.
