Point Plot in Seaborn is used to show point estimates and confidence intervals using scatter plot glyphs. The seaborn.pointplot() is used for this. For explicit order, use the order parameter of the pointplot() method.Let’s say the following is our dataset in the form of a CSV file − Cricketers.csvAt first, import the required libraries −import seaborn as sb import pandas as pd import matplotlib.pyplot as pltLoad data from a CSV file into a Pandas DataFrame −dataFrame = pd.read_csv("C:\Users\amit_\Desktop\Cricketers.csv")Plotting point plot with “Academy” and “Age”. Control order by passing an explicit order i.e. ordering on the basis of "Academy". Ordering using ... Read More
The app.engine() method is used for registering the given template engine callback as "ext". The require() method needs the engine based on the function by default.Use the following methods for engines that do not provide the extensions (or want to map different extensions) or express out of the box.app.engine('html', require('ejs').renderFile)Syntaxapp.engine(ext, callback)Example 1Create a file with the name "appEngine.js" and copy the following code snippet. After creating the file, use the command "node appEngine.js" to run this code.// app.engine() Method Demo Example // Importing the express module const express = require('express'); // Initializing the express and port number var ...

Point Plot in Seaborn is used to show point estimates and confidence intervals using scatter plot glyphs. The seaborn.pointplot() is used for this. To avoid drawing lines to connect points, simply set the “join” parameter of the pointplot() method to False.Let’s say the following is our dataset in the form of a CSV file − Cricketers.csvAt first, import the required libraries −import seaborn as sb import pandas as pd import matplotlib.pyplot as pltLoad data from a CSV file into a Pandas DataFrame −dataFrame = pd.read_csv("C:\Users\amit_\Desktop\Cricketers.csv")Now, plot the Horizontal point plot. The “join” parameter is set as False to avoid drawing ... Read More
To create a Time Series Plot with multiple columns using Line Plot, use the lineplot(). At first, import the required libraries −import seaborn as sb import pandas as pd import matplotlib.pyplot as pltCreate a DataFrame. We have multiple columns in our DataFrame −dataFrame = pd.DataFrame({'Date_of_Purchase': ['2018-07-25', '2018-10-25', '2019-01-25', '2019-05-25', '2019-08-25', '2020-09-25', '2021-03-25'], 'Units Sold': [98, 77, 51, 70, 70, 87, 76], 'Units Returned' : [60, 50, 40, 57, 62, 51, 60] })Plot time series plot for multiple columns −sb.lineplot(x="Date_of_Purchase", y="Units Sold", data=dataFrame) sb.lineplot(x="Date_of_Purchase", y="Units Returned", data=dataFrame)ExampleFollowing is the code −import seaborn as sb import pandas as pd import matplotlib.pyplot as ...

Horizontal point plots are a plotting based on the values of x and y i.e. the columns of the dataset you consider. Point Plot in Seaborn is used to show point estimates and confidence intervals using scatter plot glyphs. The seaborn.pointplot() is used for this.Let’s say the following is our dataset in the form of a CSV file − Cricketers.csvAt first, import the required libraries −import seaborn as sb import pandas as pd import matplotlib.pyplot as pltLoad data from a CSV file into a Pandas DataFrame −dataFrame = pd.read_csv("C:\Users\amit_\Desktop\Cricketers.csv")Now, use the pointplot() and set the x and y values −sb.pointplot(x ...

The app.enable() function sets the Boolean setting ‘name’ to ‘true’, where name defines one of the properties from the app settings table. Using the app.set('foo', true) for a Boolean property is same as calling the app.enable('foo') function.Syntaxapp.enable(name)Example 1Create a file with the name "appEnable.js" and copy the following code snippet. After creating the file, use the command "node appEnable.js" to run this code.// app.enable() Method Demo Example // Importing the express module const express = require('express'); // Initializing the express and port number var app = express(); // Initializing the router from express var router = express.Router(); ...

The app.disable() method disables the setting name passed in the function. This method sets the setting name to False. We can perform the same function by using the app.set() method too, by passing its value as False.Syntaxapp.disable(name)Example 1Create a file with the name "appDisable.js" and copy the following code snippet. After creating the file, use the command "node appDisable.js" to run this code.// app.disable() Method Demo Example // Importing the express module const express = require('express'); // Initializing the express and port number var app = express(); // Initializing the router from express var router = express.Router(); ...

To apply the aggregation list, use the agg() method. At first, import the required library −import pandas as pdCreate a DataFrame with two columns −dataFrame = pd.DataFrame( { "Car": ['BMW', 'Lexus', 'Lexus', 'Mustang', 'Bentley', 'Mustang'], "Units": [100, 150, 110, 80, 110, 90] } )Specifying list as argument using agg() −dataFrame = dataFrame.groupby('Car').agg(list) ExampleFollowing is the complete code −import pandas as pd # Create DataFrame dataFrame = pd.DataFrame( { "Car": ['BMW', 'Lexus', 'Lexus', 'Mustang', 'Bentley', 'Mustang'], "Units": [100, 150, 110, 80, 110, 90] } ) ...

The app.delete() method routes all the HTTP DELETE requests to the specified path with the specified callback functions.Syntaxapp.delete(path, callback, [callback])Parameterspath − This is the path for which the middleware function is invoked. A path can be a string, path pattern, a regular expression, or an array of all these.callback − These are the middleware functions or a series of middleware functions that act like a middleware except that these callbacks can invoke next (route).Example 1Create a file "appDelete.js" and copy the following code snippet. After creating the file, use the command "node appDelete.js" to run this code.// app.delete() Method Demo ... Read More
Point Plot in Seaborn is used to show point estimates and confidence intervals using scatter plot glyphs. The seaborn.pointplot() is used for this. For vertical point plot grouped by a categorical variable, set the variable as a value for the pointplot().Let’s say the following is our dataset in the form of a CSV file − Cricketers.csvAt first, import the required libraries −import seaborn as sb import pandas as pd import matplotlib.pyplot as pltLoad data from a CSV file into a Pandas DataFrame −dataFrame = pd.read_csv("C:\Users\amit_\Desktop\Cricketers.csv") Vertical point plot grouped by a categorical variable −sb.pointplot(dataFrame['Role'], dataFrame['Age'])ExampleFollowing is the code −import seaborn ...
