I have this table with percentatge values over time. When I do a scatter plot i get the following:
I would like tot fit a line over these points so that it show like this:
I know probably is easy to do, but I amb quite new to matlab programming and I've been wasting a couple of hours trying to do it but I am just getting different errors for each new method I try. I just could plot a linear regression, which I didn't want because it does not fit the plot shape.
Thank you in advance

Do you have the curvefitting toolbox or the optimisation toolbox?
If not, then you have made more work for yourself, but you can always follow:

Curve fitting app would suit you.
You can play around the various methods built in MATLAB.

figure( 'Name', 'B3 and B4' );
hold on;
plot(fitresult{1}, 'b');
plot(xData_B3, yData_B3, 'bo');
plot(fitresult{2}, 'r');
plot(xData_B4, yData_B4, 'ro');
hold off;
Try this!?
