How do I show two different scales on my Line chart?
Posted by Todd Shafer at 17:05 on Thursday 17th March 2022[link]
I need to make a line chart with two lines of data. On the left, I want to use data1 and on the right data2. The reason I want to do this is because data1 use numbers ranging from 0 to 500 and data2 uses 0 to 100,000. As a result, if I put the 2 data's together the 0 to 500 gets pushed to the bottom of the graph. If I can separate them the numbers will be more visible. Can help me with this? Thanks!

I can think of two ways to do this:
1. Use a logarithmic scale which goes something like this: 0,10,100,1000,10000,100000 so smaller values are more prominent than they normally would be. There's a demo of a logarithmic scale in the demos in the down called line-logarithmic-scale.html and also there's one here too: https://www.rgraph.net/demos/bar-logarithmic-scale.html This is not my preferred solution though...
2. ...Because this is: Using two Line charts, one layered on top of the other which also have the scales on different sides of the chart. There's a demo of this here:
