How can I flip this line upside down:
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/160336/image.png)
This is my code that may not need flipud() :
x = [1 2 3];
y = [2 2.5 3.5];
flipud(plot(x,y))

Because it is a line object. There is only one line. Of course, it depends what version of Matlab you are using. If you are < R2014b then it will simply be a 'magic' double which you can query for the line properties.
Take a look at the output of
h = plot( x, y )
on the command line and you will see what it is. It is an object containing many useful properties of the line - e.g. colour, width, x data, y data

figure; hAxes = gca;
x = [1 2 3];
y = [2 2.5 3.5];
plot( hAxes, x, y )
set( hAxes, 'YDir', 'reverse' ) % Or hAxes.YDir = 'reverse' from R2014b onwards

Then you probably want the above maths or something similar. If you want 20 to become 70 then just substitute 70 and 20 in instead of max( data ) and min( data )
