Multiple y axes not staying aligned

Hi there,

I have some data that updates every day, where one series exists between 0 and 75, and the other series exists between -15 to 4. I want to try and show multiple y axes on the chart for the different series, but whenever I do this, the primary y-axis starts at -18, and the secondary y-axis starts at 0.

Is there a way to get these axes to align (and stay aligned as new data comes in), such that 0 on the primary axis is at the same level as 0 on the secondary axis?

Re: Multiple y axes not staying aligned

Welcome to our forum and thanks for contacting us with your question!

You need to have the same min and max on both axis to align the 0 value level, see:

Let me know if you have any further questions!
