Matplotlib has a default color cycle for all the graphs and plots, however, in order to draw plots with multiple color cycles, we can use the cycler property of Matplotlib. It is used to plot repetitive patterns for the axis.First, we will use the Object Oriented APIs such as pyplot to plot the specific visualization.from cycler import cycler import numpy as np from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas from matplotlib.figure import Figure from IPython.core.display import displayIn this example, we will create two objects which will repeat the cycle after every four objects. Thus, after creating two objects, the last two ...

Let us assume that we want to animate a nature of function which is exponentially decaying like y = a(b)^x where b = growth factor and a = initial value.An exponentially decay function would look like this, However, for now, we want to animate and plot the exponentially decaying tan function.First import the libraries, import numpy as np import matplotlib.pyplot as plt from matplotlib.animation import FuncAnimationDefine the axes, fig, a = plt.subplots()Plotting a blank figure with axes,   xdata, ydata = [], [] line, = ax.plot(xdata, ydata)Set the limit of the grids, ax.set_xlim(0, 10) ax.set_ylim(-3.0, 3.0) ax.grid()   Define the function to ...

To create a custom marker on a plot or graph, we use a list where we write the markers we want to see in the plot. The markers are nothing but symbols, emoji, character or any character which we want to see on the figure.In order to create the marker, we will first import the required libraries.import matplotlib.pyplot as plt import numpy as npFor now, we will create a marker on a sine curve. Let us create the grid with size (12, 6), x = np.arange(1, 2.6, 0.1) y = np.sin(2 * np.pi * x) plt.subplots(figsize=(12, 6))Here we will create ...

In a given matrix, there are four objects to analyze the element position: left, right, bottom and top.Breadth First Search is nothing but finding the shortest distance between the two elements of a given 2-D Matrix. Thus in each cell, there are four operations we can perform which can be expressed in four numerals such as, '2' describes that the cell in the matrix is Source.'3' describes that the cell in the matrix is Destination.'1' describes that the cell can be moved further in a direction.'0' describes that the cell in the matrix can not be moved in any direction.On ...

A linear model can be built with estimators to load the titanic dataset using the ‘read_csv’ method which is present in ‘Pandas’ package. This method takes google APIs that store the titanic dataset. The API is read and the data is stored in the form of a CSV file.Read More: What is TensorFlow and how Keras work with TensorFlow to create Neural Networks?We will use the Keras Sequential API, which is helpful in building a sequential model that is used to work with a plain stack of layers, where every layer has exactly one input tensor and one output tensor.A ...
