In Google Sheets, I'm having some difficulty getting two curves on the same axis.
How do I get a set of axis with 2 sets of x,y values on it.
And I tried to go with the suggestion there and I have come up with
I find it a bit strange, 'cos the legend shows amp as blue and amp2 as red. But the graph only shows a red curve. And the values plotted are (t,amp). It doesn't have (t2,amp2).
I want it to show (t,amp), and also overlayed on that, (t2,amp2).
I have picked for series(which tells google sheets y axis I suppose), amp and amp2.
I then tried adding this into the "data range" box "A49:D58,C49:C54" but as you see below, it still only shows one graph.
