# Tornado charts Tornado charts can be used best for comparing two values such as the salaries of men and women. To create a tornado chart, insert bar charts for the two columns and reverse the axis direction for one of the columns. These charts can be further customised using the options - (a) axis direction (b) reference line and band (c) comparison band (d) data label (e) fill pattern and more. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
