Then, you can use Matplotlib's plt.plot() function to plot the points on a graph. Make sure to import matplotlib.pyplot as plt at the beginning of your code. You can also customize the appearance of the plot by adding labels, titles, and formatting options. Finally, call plt.show() to display the plot.

A higher standard deviation indicates higher volatility.Another measure of volatility is beta, which compares the stock's price movements to the overall market.

3 min readIn matplotlib, you can set the color range by using the vmin and vmax parameters in the imshow function. These parameters allow you to specify the minimum and maximum values for the color map. By setting the vmin and vmax values, you can control the color range and ensure that the colors in your plot accurately reflect the data values. This can be particularly useful when working with datasets that have a wide range of values and you want to emphasize certain parts of the data.

This class allows you to define a colormap with multiple colors and their corresponding positions along the gradient.First, you need to define a list of colors that you want to include in your custom gradient. Each color should be specified as a tuple of RGBA values.

This function takes the x-coordinate where you want the vertical line to be placed as one of its arguments. You can also provide additional arguments such as the line style, color, and label for the annotation. After adding the vertical line to your plot, you can use the plt.annotate() function to add text or other annotations at a specific position relative to the line.

This function takes an optional labels parameter where you can specify the names of the labels you want to display in the legend. You can also customize the location of the legend using the loc parameter, which takes values such as "upper right", "lower left", "center", etc.

6 min readIn matplotlib, double markers can be used to emphasize certain points on a plot. To achieve this, you can simply use the 'marker' parameter twice in the plot function. For example, if you want to use a red circle as the main marker and a blue triangle as the secondary marker, you can specify it as follows:plt.plot(x, y, marker='o', markerfacecolor='red', markeredgecolor='black', markersize=10, linestyle='-', color='black') plt.
