3 min readTo change the background color of a matplotlib chart, you can use the set_facecolor() method on the figure object. For example, you can set the background color to white by calling plt.figure().set_facecolor('white'). Alternatively, you can specify the background color when creating the figure by passing the facecolor parameter to the plt.figure() function. You can choose any color by specifying its name or its RGB values.

4 min readTo create a stacked histogram using matplotlib, you can use the hist() function and set the bottom parameter for the second histogram to stack it on top of the first one. You can also adjust the transparency of the bars using the alpha parameter to make it easier to see the stacked bars. Make sure to provide the necessary data for both histograms and customize the appearance as needed to create a visually appealing stacked histogram.

6 min readScaling figures with Matplotlib can be done by using the figsize parameter when creating a new figure. This parameter allows you to specify the width and height of the figure in inches. By adjusting the values provided to figsize, you can scale the figure to your desired size. Additionally, you can use the tight_layout function to automatically adjust the subplots so that they fit within the figure properly.

4 min readTo plot a scatter pie chart using matplotlib, first import the necessary libraries such as matplotlib.pyplot. Next, create the data points for the scatter plot and specify the labels for the pie chart. Then, use the plt.scatter() function to plot the scatter plot with the desired data points. Finally, use the plt.pie() function to plot the pie chart with the specified labels. Customize the chart by adding a title, axis labels, and legend if needed. Display the chart using plt.show().

5 min readTo remove extra horizontal lines in a matplotlib plot, you can adjust the y-axis limits using the ylim method. Simply set the upper and lower limits of the y-axis to fit your desired range of data using plt.ylim(lower_limit, upper_limit). This will remove any extra horizontal lines that extend beyond the specified limits of the plot. Additionally, you can also use the plt.grid(False) method to remove grid lines from the plot.

6 min readTo add vertical grid lines to a matplotlib chart, you can use the grid method to specify which grid lines you want to display. By default, all grid lines are hidden but can be turned on by setting the which parameter to 'major' or 'minor', depending on whether you want to show the major or minor grid lines.For vertical grid lines specifically, you would use the axis parameter and set it to 'x' to show vertical grid lines along the x-axis.

4 min readTo create a 3D circle in Matplotlib, you can use the Axes3D module from the mpl_toolkits.mplot3d library. By defining a range of angles and using trigonometric functions, you can plot points on the surface of a circle in 3D space. You can then use the plot_surface function to connect these points and create a 3D representation of a circle. Additionally, you can customize the appearance of the circle by setting parameters such as the radius, color, and transparency.

6 min readTo create a new instance of Matplotlib axes, you can use the plt.subplots() function, which returns a Figure object and an Axes object. You can also use the plt.figure() function to create a new Figure object and then add axes to it using the add_axes() method. Additionally, you can use the plt.subplot() function to create a new subplot within an existing Figure object. Each of these methods allows you to create a new instance of Matplotlib axes that can be customized and plotted on as needed.

3 min readTo properly plot a bar chart with matplotlib, you first need to import the necessary libraries, such as matplotlib.pyplot. Then, you can use the plt.bar() function to specify the data you want to plot on the chart. Make sure to provide both the x-axis values and y-axis values for the bars. You can customize the appearance of the chart by setting various parameters, such as color, width, and labels. Finally, use plt.show() to display the bar chart.
