To make matplotlib.pyplot stop forcing the style of markers, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create random x and y data points using numpy.Plot x and y data points using plot() method, with "r*" marker with markersize=10.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.random.rand(20) y = np.random.rand(20) plt.plot(x, y, 'r*', markersize=10) plt.show()Output
To set the limits on a colorbar of a countour plot in Matplotlib, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create x and y data points using numpy.Get the data using x and y.Get the coordinate matrices from the coordinate vectors.Initialize vmin and vmax to set the limits on a colorbar of a contour plot in matplotlib.Plot contours using contourf() method.Make the colorbar using scalar mappable within the range of vmin and vmax.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt import numpy as np from ...

To make xtick labels of a plot be simple drawings using Matplotlib, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Initialize the y position of simple drawings.Create a new figure or activate an existing figure using figure() method.Add an '~.axes.Axes' to the figure as part of a subplot arrangement using add_subplot()method.Plot a line using plot() method.Set the X-axis ticks using set_ticks() method.Set empty tick labels.Add circles and rectangles patches using add_patch() method. Instantiate Circle() and Rectangle() class.To display the figure, use show() method.Exampleimport matplotlib.pyplot as plt import matplotlib.patches as patches ... Read More
To indicate the statistically significant difference in bar graph, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create means, std, index, width and labels data points.Create a figure and a set of subplots using subplots() method.Make a bar plot using bar() method.Plot Y versus X as lines and/or markers with attached errorbars.Scale the Y-axis.Get or set the current tick locations and labels of the X-axis.To display the figure, use show() method.Exampleimport numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True means = (5, 15, ...

To show node name in graphs using networkx, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Initialize a graph with edges, name, or graph attributes.Add multiple nodes using add_nodes_from() method.Add all the edges using add_edge_from() method.Draw the graph G with Matplotlib using draw() method. Set with_labels to True.To display the graph, we can use show() method.Exampleimport matplotlib.pylab as plt import networkx as nx plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True G = nx.DiGraph() G.add_nodes_from([1, 2, 3, 4]) G.add_edges_from([(1, 2), (2, 1), (2, 3), (1, 4), (3, 4)]) nx.draw(G, ...

Tkinter canvas widget is used for many different purposes such as adding objects, drawing shapes, images and complex visuals to a graphical interface in an application. We can also configure its style such as background color, foreground color, and other properties using the configure properties or passing attributes.Suppose we want to inherit the background color of the Canvas widget in another widget or in some part of the application. This can be achieved by using my_canvas["background"] property. Further, we can use canvas["background"] to fetch the background color of the canvas widget.Example# Import the required library from tkinter import * from ... Read More
In order to work with Tabs and separate your workflow in an application, Tkinter provides a Notebook widget. We can use the Notebook widget to create Tabs in an application. Tabs are useful to isolate one particular frame or event from another.Generally, Notebook widget can be configured and styled using the ttk themed widget. So, to style a Notebook widget, we pass TNotebook and TNotebook.Tab parameters in the configuration. If we click on a particular Tab, there may appear some rectangular dashed line which can be removed.Example# Import the required library from tkinter import * from tkinter import ttk ... Read More
Tkinter has many inbuilt features and attributes that help the application developer to build a robust and featured application. We can set the attributes such as background color, foreground color, and other properties of a widget using the configure method in Tkinter.To set the background color or foreground color of a widget, we can use both default and RGB color codes. RGB is defined by the 6 digit alphanumeric character containing different digits of R, G, B values. In order to use RGB color codes in tkinter, we have to define it using the format #aab123.Example# Import the required libraries ... Read More
Tkinter Events are very useful for making an application interactive and functional. It provides a way to interact with the internal functionality of the application and helps them to rise whenever we perform a Click or Keypress event.In order to schedule the events in tkinter, we generally use the bind('Button', callback) method. We can bind any key to perform certain tasks or events in the application. To bind the Esc key such that it will close the application window, we have to pass the Key and a callback event as the parameter in the bind(key, callback) method.Example# Import the required ...

Dialog Boxes are a very essential component of any application. It is generally used to interact with the user and the application interface. We can create dialog boxes for any tkinter application using the Toplevel window and other widgets. The toplevel window pops up the stuff above all the other windows. Thus, we can add more stuff on the toplevel window for building dialog boxes.ExampleIn this example, we have created a modal dialog which has two parts, Initialization of the Toplevel window.Function Definition for Popup Dialog Event.Adding widgets in the Toplevel window.Function Definition for Dialog options.# Import required libraries from ...
