Openpyxl is a Python library using which one can perform multiple operations on excel files like reading, writing, arithmatic operations and plotting graphs.
Charts are composed of at least one series of one or more data points. Series themselves are comprised of references to cell ranges. Let’s see how to plot Doughnot, Radar, Surface, 3D Surface Chart on an excel sheet using openpyxl.
For plotting the charts on an excel sheet, firstly, create chart object of specific chart class( i.e SurfaceChart, RadarChart etc.). After creating chart objects, insert data in it and lastly, add that chart object in the sheet object. Let’s see how to plot different charts using realtime data.
Code #1 : Plot the Doughnut Chart
Doughnut charts are similar to pie charts except that they use a ring instead of a circle. They can also plot several series of data as concentric rings. For plotting the Doughnut chart on an excel sheet, use DoughnutChart class from openpyxl.chart submodule.
Code #2: Plot the Radar Chart
Data that is arranged in columns or rows on a worksheet can be plotted in a radar chart. Radar charts compare the aggregate values of multiple data series. It is effectively a projection of an area chart on a circular x-axis. For plotting the Radar chart on an excel sheet, use RadarChart class from openpyxl.chart submodule.
Code #3 : Plot The Surface Chart
Data that is arranged in columns or rows on a worksheet can be plotted in a surface chart. A surface chart is useful when you want to find optimum combinations between two sets of data. As in a topographic map, colors and patterns indicate areas that are in the same range of values. For plotting the Surface chart on an excel sheet, use SurfaceChart class from openpyxl.chart submodule.
Code #4 : Plot the Surface 3D chart
For plotting the 3D Surface chart on an excel sheet, use SurfaceChart3D class from openpyxl.chart submodule.
