How to show on the chart two indicators with very different values?

Question

infographics

Good day!
The situation is as follows - I display two parameters on one graph. For one of them, the maximum is much larger than for the other, for example, maximum x1 = ~[400-800], maximum x2 =~[5-15]
something like this
. Please advise how best to display this so that it is visual? Perhaps you should choose a different type of chart?

Answer 1

As an option - use two scales along the y-axis, with different scales.
For your case, a scale of 50 is suitable.
Max x2 will be 750, min x2 - 250.
Either describe all this in a note, or (even better) draw another vertical one to the left of the existing y axis - from 0 to 15, where 15 will be at the 750 scale level y1.
