Line of best fit not plotting correctly

9 views (last 30 days)
Hi,
When I use the graph app to find a line of best fit to my data, everything seems to be working fine (see attached image).
But when I try to plot this line of best fit alongside the scatter data, the line is nowhere near. Does anyone know what might be going on?
figure
scatter(E5half41,logI5_41,5)
hold on
y=-0.1172.*E5half41+3.954;
plot(y,E5half41)
cheers!

Try this —
plot(E5half41, y)
The independent variable is the first argument.
I cannot run the code without the data, however that would appear to be an appropriate guess as to what the problem is.

@Em, X and Y are flipped, for the best fit line plot, compared to what they should be.
