Multiple Axes in F#

How to make a graph with multiple axes (dual y-axis plots, plots with secondary axes) in F#.

Plotly is known for its graphing libraries, but it's also a broader ecosystem for building interactive data apps, AI data analysis tools, and deploying and hosting Dash apps. Explore the full set of tools and platforms designed to help turn data into action. Discover Plotly.

Note: We are retiring documentation for R, MATLAB, Julia, and F#. Learn more about this change here.

Two Y Axes¶

Multiple Axes are created by defining AxisAnchor for the plot as shown below
