To pick a new color for each plotted line within a figure, use the following steps −Setup X-axis and Y-axis labels for the diagram.Set the current .rc parameters. For axes facecolor, the group is axes.Use a cycler to set the color for the group of lines. The color list consists of ‘r’ for red, ‘g’ for green, ‘b’ for blue, and ‘y’ for yellow.Cycler class helps to create a new Cycler object from a single positional argument, a pair of positional arguments, or the combination of keyword arguments.Plot the number of lines with different colors.Use plt.show() to show the figure.Exampleimport ...

To hide the axis value but to keep the axis tick labels, we can perform the following steps −Plot a line using the plot( ) method.Set X and Y labels using x label and y label methods.Using plt.gca(), get the current axis, creating one if necessary.Use xaxis.set_ticklabels() with an empty list.Use yaxis.set_ticklabels() with an empty list.To show the diagram, use the plt.show() method.Exampleimport matplotlib.pyplot as plt plt.plot([0, 5], [0, 5]) plt.ylabel("Y-axis ") plt.xlabel("X-axis ") ax = plt.gca() ax.axes.xaxis.set_ticklabels([]) ax.axes.yaxis.set_ticklabels([]) plt.show()OutputRead More
To save the images in Python with very high quality, you need to follow the steps given below −Create fig and ax variables using subplots method, where default nrows and ncols are 1.Plot the lines using plot() method.We can add axes labels using ylabel() and xlabel().To get a high-quality image, we can use .eps image format.You can increase the dot per inch value, i.e., dpi.Using savefig() method, we can save the image locally.To show the figure, use plt.show().Exampleimport matplotlib.pyplot as plt fig, ax = plt.subplots() plt.plot([0, 5], [0, 5]) plt.ylabel("Y-axis ") plt.xlabel("X-axis ") image_format = 'eps' ...

To shift the Y-axis ticks from left to right, we can perform the following steps −Create a figure using the figure() method.Using the above figure method, create the axis of the plot, using add_subplot(xyz), where x is row, y is column, and z is index.To shift the Y-axis ticks from left to right, use ax.yaxis.tick_right() where ax is axis created using add_subplot(xyz) method.Now plot the line using plot() method, with given x and y points, where x and y points can be created using np.array() method.Set up x and y labels, e.g., X-axis and Y-axis , using xlabel and ylabel ...

In this problem, we are given an integer N. Our task is to create a program to Find Nth term of series 0, 2, 4, 8, 12, 18…Let’s take an example to understand the problem, InputN = 5Output12Solution ApproachA simple approach to solve the problem is the formula for the Nth term of the series. For this, we need to observe the series and then generalise the Nth term.The formula of Nth term isT(N) = ( N + (N - 1)*N ) / 2Program to illustrate the working of our solution, Example Live Demo#include using namespace std; int calcNthTerm(int N) ...

In this problem, we are given an integer N. Our task is to create a program to Find Nth term of series 1, 4, 15, 72, 420…Let’s take an example to understand the problem, InputN = 4Output72Solution ApproachA simple approach to solve the problem is the formula for the Nth term of the series. For this, we need to observe the series and then generalise the Nth term.The series can be seen as the product of factorial and a some variables, 1, 4, 15, 72, 420… 1!*(X1), 2!*(X2), 3!*(X3), 4!*(X4), 5!*(X5)... 1*(1), 2*(2), 6*(5/2), 24*(3), 120*(7/2)...Here, the series of product ...

In this problem, we are given two integer values N and X. Our task is to create a program to Find Nth positive number whose digital root is X.Digital Root (X) is a single digit positive number which is found by adding digits of N recursively adding digits, till the sum becomes single digit.Let’s take an example to understand the problem, InputN = 5, X = 4Output40Solution ApproachA simple way to solve the problem is by counting the numbers with a digital root is X. For this, we will start from 1 and then check if the current number’s digital ... Read More
In this problem, we are given an integer value N. Our task is to create a program to Find Nth number of the series 1, 6, 15, 28, 45, …In the series, every element is 2 less than the mean of the previous and next element.Let’s take an example to understand the problem, InputN = 5Output45Solution ApproachThe Nth term of the series 1, 6, 15, 28, 45, … can be found using the formula, TN = 2*N*N - NProgram to illustrate the working of our solution, Example Live Demo#include using namespace std; #define mod 1000000009 int calcNthTerm(long n) { ...
