In a function graph, sometimes the independent variable X and the dependent variable Y correspond exponentially, so the scale of the coordinate axis needs to be set to a logarithmic scale. This article will tell you how to implement it in Matplotlib by resetting the axis format with examples.
Traversal is a required operation in many programming languages, such as Python, which iterates over list structures through the for loop. How do Pandas traverse Series and DataFrame objects? We should make it clear that they have different types of data structures and then different traversal methods. This article will tell you the difference between …
1. How To Iterate Over Numpy Array. NumPy provides the nditer() function to get the iterator object that can be used in conjunction with the for loop to iterate over array elements. The following example uses the range() function to create a 2*3 array and nditer to generate an iterator object. import numpy as np def numpy_array_iterator_example(): …
The grid() method provided by the Matplotlib axes object can turn on (show) or off (hide) the grid in the canvas and the primary/secondary scale of the grid. In addition, the grid() function can also set the color, line type, line weight, and other properties of the grid. This article will show you an example …

This article will tell you what is DataFrame reindex and why we need to reindex and how to reindex with examples.
The broadcast mechanism in NumPy aims to solve the problem of arithmetic operation between arrays of different shapes.
The matplotlib.pyplot module provides the function subplot2grid(), which creates axes objects ( plot areas ) at specific locations on the canvas. Not only that, but it can also use a different number of rows and columns to create drawing areas with different spans. Unlike the subplot() and subplots() functions, the subplot2gird() function splits the canvas …

If you want to apply custom functions or apply functions from other libraries to pandas objects, you can use the below three methods. 1). Use the pipe() function to operate on the entire pandas’ DataFrame object. 2). Use the apply() function to operate on the pandas’ DataFrame object’s rows or columns. 3). Use the applymap() function …
In NumPy, if you want to access or modify the elements of an array, you can use indexes or slices, such as accessing the elements of an array using an index starting at 0, which is the same as Python’s list.
This article shows you how to insert another plot into the same figure canvas by adding axes objects to the figure, then you can plot multiple plots on the same figure using Python Matplotlib.
