An area chart represents the change in a one or more quantities over time. It is made by plotting a series of data points over time, connecting those data points with line segments, and then filling in the area between the line and the x-axis with color or shading.Example# import xlsxwriter module import xlsxwriter ...

Charts are composed of at least one series of one or more data points. Series themselves are comprised of references to cell ranges. For plotting the charts on an excel sheet, firstly, create chart object of specific chart type( i.e Column chart etc.). After creating chart objects, insert data in ... Read More

One of the basic problems for many complex problems is finding numbers greater than certain number in list in python, is commonly encountered.Example Live Demo# find number of elements > k using for loop # initializing list test_list = [1, 7, 5, 6, 3, 8] # initializing k k = 4 ... Read More

Polynomial Regression is a form of linear regression in which the relationship between the independent variable x and dependent variable y is modeled as an nth degree polynomial. Polynomial regression fits a nonlinear relationship between the value of x and the corresponding conditional mean of y, denoted E(y |x)Example# Importing the libraries import ... Read More

It is a step of Data pre-processing which is applied to independent variables or features of data. It basically helps to normalise the data within a particular range.Why scaling?Most of the times, your dataset will contain features highly varying in magnitudes, units and range. But since, most of the machine ... Read More

SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python. SymPy only depends on mpmath, a pure Python library for ... Read More

C# interface members can be implemented explicitly or implicitly.Implicit implementations don't include the name of the interface being implemented before the member name, so the compiler infers this. The members will be exposed as public and will be accessible when the object is cast as the concrete type.The call of ... Read More

Order by is used to sort the arrays in the ascending or in the descending orderGroupBy operator belong to Grouping Operators category. This operator takes a flat sequence of items, organize that sequence into groups (IGrouping) based on a specific key and return groups of sequenceExampleclass ElectronicGoods {    public ... Read More
