To use colorbar with hist2d in matplotlib.pyplot, we can take the following steps.StepsSet the figure size and adjust the padding between and around the subplots.Initialize a variable "N" for the number of sample data.Createx and y data points using numpy.Create a figure and a set of subplots using subplots() method.Make a 2D histogram plot using hist2D().Create a colorbar for the hist2d scalar mappable instance.To display the figure, use Show() method.Examplefrom matplotlib.colors import LogNorm import matplotlib.pyplot as plt import numpy as np # Set the figure size plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True # Number of sample data ...

To use unicode symbols in matplotlib, we can take the following steps.StepsSet the figure size and adjust the padding between and around the subplots.Add text to figure, using text() method with unicode symbols. Here we have used the Unicode chararacter (Δ) which has the character code (0394).To display the figure, use Show() method.Exampleimport matplotlib.pyplot as plt # Set the figure size plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True # Unicode symbol plt.text(0.5, 0.5, s=u"\u0394", fontsize=50) # Display the plot plt.show() OutputIt will produce the following output −Now, let's use another Unicode character (\u2734).It will produce the following ...

The ng-class Directive in angularjs allows the user to dynamically set the CSS classes on an HTML element by databinding an expression which will further represent all those classes to be added. The class is only added if the expression inside the ngClass Directive returns True, else it will not be added. It is supported by all the HTML elements.The directive does not set any duplicate class if it was already set. When the expression changes, the previously added classes will be removed and the new classes will be added only after that.Syntax..Content..Example − ngClass DirectiveCreate a file "ngClass.html" in ...

The ng-mousedown Directive in AngularJS basically specifies a custom event on mouse-down event. We can perform multiple functions whenever the mouse is pressed and the mouse-down event is called.Syntax..content..Example − ngMousedown DirectiveCreate a file "ngMousedown.html" in your Angular project directory and copy-paste the following code snippet. ngMousedown Directive Welcome to Tutorials Point angularjs | ngMousedown Directive Click mouse and hold !!! OutputTo run the above code, just go to your file and run it as a normal HTML file.Your browser does not support HTML5 video.
The ng-app Directive in AngularJS is used for auto-bootstraping of an AngularJS application. This directive gives the root element of the application and is generally placed near the root element of the page like on the or tags. This directive declares the root context from where the application will be started.Points to note while using the ngApp Directive −Only one application can be bootstrapped per the HTML element. If you declare multiple ngApp components, the first ngApp appearing element will be considered as the root element for auto-bootstrap. For running multiple applications in the HTML, one should use the ... Read More
The angular.element() method wraps the raw DOM element or the HTML string as a jQuery element. If jQuery is available or imported, angular.element is an alias for the jQuery function, else this method delegates to AngularJS’s built-in subset of jQuery called jQueryLite or jqLite.Syntaxangular.element(element)Example − Wrapping the DOM element using angular.element()Create a file "element.html" in your Angular project directory and copy-paste the following code snippet. angular.element() Welcome to Tutorials Point ...

Tkinter creates a default window with its default size while initializing the application. We can customize the geometry of the window using the geometry method.However, in order to maximize the window, we can use the state() method which can be used for scaling the tkinter window. It maximizes the window after passing the “zoomed” state value to it.Example#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Set the geometry of frame win.geometry("600x400") #Create a text label Label(win, text="It takes only 21 days to create a new Habit", font=('Times New Roman ...

Tkinter initially creates a window that contains application components such as widgets and control bars. We can switch a native-looking application to a full-screen application by using the attribute(‘-fullscreen’, True) method. To make the window full-screen, just invoke the method with the particular window.Example# Import tkinter library from tkinter import * # Create an instance of tkinter frame or window win = Tk() # Set the geometry of tkinter frame win.geometry("750x250") # Create a Text widget text= Label(win, text=" HelloWelcome to Tutorialspoint.com!", font=('Century Schoolbook', 20, 'italic bold')) text.pack(pady=30) win.attributes('-fullscreen', True) win.mainloop()OutputExecuting the above code will ...

The ng-copy Directive in AngularJS is used for specifying any custom behaviour while copying the texts in input text fields. We can use this directive to call certain methods that will be triggered while the text is copied from the input field. This directive is supported by all types of input elements.Syntax..content..Example − ngCopy DirectiveCreate a file "ngCopy.html" in your Angular project directory and copy-paste the following code snippet. ngCopy Directive .index {color: white; background-color: green;} ...
