A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice, is proportional to the quantity it represents.Example# import xlsxwriter module import xlsxwriter # Workbook() takes one, non-optional, argument which is the filename #that we want to create. workbook = xlsxwriter.Workbook('chart_pie.xlsx') # The workbook object is then used to add new worksheet via the #add_worksheet() method. worksheet = workbook.add_worksheet() # Create a new Format object to formats cells in worksheets using #add_format() method .   # here we create bold format object . bold ...

A line chart is a graphical representation of an asset's historical price action that connects a series of data points with a continuous line. This is the most basic type of chart used in finance and typically only depicts a security's closing prices over time.Example# import xlsxwriter module import xlsxwriter # Workbook() takes one, non-optional, argument which is the filename #that we want to create. workbook = xlsxwriter.Workbook('chart_Line.xlsx') # The workbook object is then used to add new worksheet via the #add_worksheet() method. worksheet = workbook.add_worksheet() # Create a new Format object to formats cells in worksheets using #add_format() method . # here we create ...

Donut Chart (also known as Doughnut chart) is a variation on a Pie chart except it has a round hole in the center which makes it look like a donut, hence the name. This empty space can be used to display additional data.Example# import xlsxwriter module import xlsxwriter # Workbook() takes one, non-optional, argument which is the filename #that we want to create. workbook = xlsxwriter.Workbook('chart_doughnut1.xlsx') # The workbook object is then used to add new worksheet via the #add_worksheet() method.   worksheet = workbook.add_worksheet() # Create a new Format object to formats cells in worksheets using # add_format() method . # here we create ...

XlsxWriter is a Python library using which one can perform multiple operations on excel files like creating, writing, arithmetic operations and plotting graphs.Example# import xlsxwriter module import xlsxwriter # Workbook() takes one, non-optional, argument which is the filename #that we want to create. workbook = xlsxwriter.Workbook('chart_styles.xlsx') #Show the styles for column and area chart types. chart_types = ['column', 'area'] for chart_type in chart_types:    # The workbook object is then used to add new worksheet via the #add_worksheet() method.    # Add a worksheet for each chart type    worksheet = workbook.add_worksheet(chart_type.title())    # set zoom option    worksheet.set_zoom(30)    # ...

A column chart is a data visualization where each category is represented by a rectangle, with the height of the rectangle being proportional to the values being plotted. Column charts are also known as vertical bar charts.Example# import xlsxwriter module import xlsxwriter   # Workbook() takes one, non-optional, argument which is the filename #that we want to create. workbook = xlsxwriter.Workbook('chart_column.xlsx') # The workbook object is then used to add new worksheet via the #add_worksheet() method. worksheet = workbook.add_worksheet()   # Create a new Format object to formats cells in worksheets using #add_format() method .   # here we create bold format object . bold ...

A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart.Example# import xlsxwriter module import xlsxwriter # Workbook() takes one, non-optional, argument which is the filename #that we want to create. workbook = xlsxwriter.Workbook('chart_bar.xlsx') # The workbook object is then used to add new worksheet via the #add_worksheet() method. worksheet = workbook.add_worksheet() # Create a new Format object to formats cells in worksheets using ...

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 # Workbook() takes one, non-optional, argument which is the filename #that we want to create. workbook = xlsxwriter.Workbook('chart_area.xlsx') # The workbook object is then used to add new worksheet via the #add_worksheet() method. worksheet = workbook.add_worksheet() # Create a new Format object to formats cells in worksheets using #add_format() method ...

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 it and lastly, add that chart object in the sheet object.Example# import xlsxwriter module import xlsxwriter #Workbook()takes one, non-optional, argument which is the filename #that we want to create. workbook = xlsxwriter.Workbook('chart_pattern.xlsx') # The workbook object is then used to add new worksheet via the #add_worksheet() method. worksheet = workbook.add_worksheet() ...
