Hello,
I am trying to set my axis to 'tight'. The plot has 2 Y axes using the plotyy function, and I want my second axis to be 'tight'. Whe I set it to tight, it sets both the Y and X Lims to fill in the maximum space alotted in the plot. IS there a way to only have the YLim set to tight, while holding the same default or 'auto' limits for X? I also would like it to rescale my limits in Y (it currently messes it up after the axis tight command)
Here is what I have so far, which messes up my limits in Y
subplot(6,1,6,'align'); [AX,H1,H2] = plotyy(time(1:end-1),Altitude(1:end-1),time(1:end-1),ROC,'plot');
axis(AX(2),'tight');

You could do something like
set(AX(2), 'YLIM', [min(ROC(:)), max(ROC(:))]);

I added an if else to make the smaller values look ok and the larger ones readable, but your right, with tight limits you don't get pretty values for the y axis.
set(AX(2), 'YLIM', [min(ROC(:)), max(ROC(:))]);
if max(ROC(:))>100
set(AX(2),'YTick',min(ROC(:)):3000:max(ROC(:)));
else
set(AX(2),'YTick',min(ROC(:)):5:max(ROC(:)));
end

If you use min(ROC(:)):(max(ROC(:))-min(ROC(:)))/N:max(ROC(:)) you will always get N ticks (maybe N+1). If you round the min and max to a predetermined number of digits, you can also control for that...
