Create Tornado Charts in Excel using Python

Data visualization is an essential tool, as it makes it easier to understand complex data sets and make informed decisions. Tornado charts are useful for sensitivity analysis because they provide a graphical output that enables the assessment of variation in input variables on a specific output. In this blog post, we will learn how to create tornado charts in Excel using Python.

This article covers the following topics:

What is a Tornado Chart?

A tornado chart is a form of bar chart particularly useful in comparing the extent of change in one output arising from various inputs. When it comes to choice or the assessment of risk, it makes it easy to determine which variable has the greatest impact on the result. The diminishing order of the bars generates a shape that is in the form of a tornado, thus the name.

Python Tornado Charts API in Excel

For creating tornado charts in Excel, we will leverage the charting features of the Aspose.Cells for Python API. It is an effective tool that enables developers to create, manipulate, convert, and perform other operations on Excel files in their applications.

Before diving into creating tornado charts, let’s set up our environment and install Aspose.Cells for Python.

To install Aspose.Cells for Python, please download the package or install the API from PyPI using the following pip command in your terminal:

pip install aspose-cells-python

Create a Tornado Chart in Excel using Python

After setting up the environment, we can easily create a tornado chart in an Excel worksheet by following the steps below:

  1. Load the Excel file with data using the Workbook class.
  2. Get the desired worksheet into a Worksheet class object.
  3. Add a stacked bar chart using the Charts.add() method.
  4. Access the chart by its index in a Chart class object.
  5. Set the data source for the chart using the set_chart_data_range() method.
  6. Set the required properties for the chart.
  7. Finally, save the document using the save() method.

The following code sample shows how to create a tornado chart in Excel using Python.
