6 min readTo join two matplotlib figures, you can use the add_subplot method to create a new subplot in a single figure that contains both of the original figures. First, create a new figure using plt.figure(). Then, use the add_subplot method to add subplots to the new figure. Finally, use the plt.plot function to plot the data in each subplot. You can customize the layout of the subplots using the subplot2grid function or the GridSpec class.

7 min readTo compare the return on equity (ROE) of stocks, one must calculate the ROE of each stock by dividing the company's net income by its shareholders' equity. This ratio helps to measure how efficiently a company is using its equity to generate profits.Once the ROE of each stock is calculated, one can compare them to determine which companies are more effectively utilizing their equity. A higher ROE generally indicates that a company is more profitable in relation to its equity.

5 min readTo make a 4D plot using Matplotlib, you can use the mplot3d toolkit that comes with Matplotlib. This toolkit allows you to create three-dimensional plots, but you can also use it to plot four-dimensional data by adding a color dimension.To create a 4D plot, you would typically have three spatial dimensions (x, y, z) and one additional dimension that you want to represent with color.

4 min readWhen comparing price-to-book (P/B) ratios of stocks, it is important to understand that the P/B ratio is calculated by dividing the current market price of a stock by its book value per share. The book value per share is calculated by subtracting a company's total liabilities from its total assets and dividing by the number of outstanding shares.To compare P/B ratios of stocks, investors should look for stocks with low P/B ratios as this indicates that the stock may be undervalued.

5 min readTo animate a PNG image with Matplotlib, you can use the FuncAnimation class to create a sequence of frames and then save them as a video or gif. First, you need to import the necessary libraries such as Matplotlib and NumPy. Next, load your PNG image using Matplotlib's imread function. Then, create a figure and axis using Matplotlib's subplots function. Use the imshow function to display the PNG image on the axis.

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.

6 min readTo compare earnings per share (EPS) of stocks, investors can look at the historical EPS of each company to understand how their earnings have trended over time. Additionally, investors can compare the EPS of different companies within the same industry to see how each company is performing relative to its peers.

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.

7 min readWhen comparing stocks' market capitalizations, investors should consider the total value of a company's outstanding shares of stock. 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.
