4 min readWhen comparing the price-to-earnings (P/E) ratios of different stocks, it is important to consider several factors to ensure a thorough analysis. The P/E ratio is a common valuation metric used by investors to determine if a stock is overvalued or undervalued based on its current price relative to its earnings per share (EPS).First, it is important to understand the P/E ratio itself, which is calculated by dividing the current stock price by the company's EPS.

5 min readTo force matplotlib to scale images, you can use the imshow function with the aspect parameter set to a value other than 'auto'. This parameter allows you to control the aspect ratio of the image displayed.Alternatively, you can also adjust the size of the figure using the figure function before plotting the image to achieve the desired scaling. By specifying the figsize parameter, you can set the dimensions of the figure to accommodate the image at the desired scale.

5 min readTo show a progressive curve in matplotlib, you can create a line plot with increasing values on the y-axis as you move along the x-axis. This can be achieved by generating data points that follow a progressive pattern, such as a linear or exponential increase. Once you have your data points, you can plot them using the plt.plot() function in matplotlib. Additionally, you can customize the appearance of the curve by adjusting the color, line style, and other parameters in the plot function.

This can be calculated by multiplying the current stock price by the total number of shares outstanding. By comparing the market capitalizations of different stocks, investors can gain insight into the relative size and value of different companies.

3 min readTo remove a plot in matplotlib using Python, you can simply call the remove() method on the plot object that you want to remove. For example, if you have a plot stored in a variable called plot, you can remove it by calling plot.remove(). This will remove the plot from the matplotlib figure, effectively removing it from the plot. Alternatively, you can use the cla() method to clear the entire plot, removing all plots at once. This can be done by calling plt.cla() if using the pyplot interface.

3 min readTo animate a 2D NumPy array using Matplotlib, you can first create a figure and axis object using plt.subplots() from the matplotlib.pyplot module. Then, you can use a loop to update the values in the array and plot the updated image using the imshow() function. During each iteration of the loop, you can use the pause() function to add a delay between frames and create the illusion of animation. Finally, you can display the animation using the show() function.

This parameter allows you to customize the formatting of the autopct labels that display the percentages on the chart.You can set the autopct parameter to a format string that excludes "None" values. For example, if you want to remove "None" from the labels, you can use the format string '%1.

5 min readTo create a ternary diagram (or any-ary diagram) in matplotlib, you can use the plt.fill function to plot the points on the diagram. First, you need to define the vertices of the ternary plot and then plot the points by specifying the coordinates of the points in terms of the percentages of the three components that make up the ternary plot. You can customize the plot by adding labels, titles, legends, and gridlines to make the diagram more informative and visually appealing.
