I have attached files
I have made a code that plots the values.
And I need to find a x -value when y-vale is at minimum value.
Also when I ploted, the significant figures in the plotting graph is not long enough that I can not compare the value
for instance, (using data crusor)
for x= 2, y= 0.311(322), for x=4, y= 0.311(433)
the value in bracket is omitted so I can not compare values.

[miny, minyidx] = min(y);
minx = x(minyidx);
If you want the data cursor to show more digits then you can create a custom data cursor callback.
