Can set the lower limit of the axis manually but leaving to auto the upper limit

I want to control only the lower limit of the axis and not the upper. I want the upper to be automatic. Is there any way to do it with set?

Answer 1

[Azzi Abdelmalek]

xlim([2 inf])
ylim([4 inf])

This one worked well for me.

Well, I actually used:

ax = gca;
ax.YLim = [0 inf];

Thanks!

I did finally this. If I want for example my lower limit to be 2:

limsy=get(gca,'YLim');
set(gca,'Ylim',[2 limsy(2)];

[Azzi Abdelmalek]

ylim([2 inf])

[Giorgos Papakonstantinou]

But this reminds the tight. I don't want it tight. I want it like it the auto

[Azzi Abdelmalek]

"But this reminds the tight" what does that mean?

[Giorgos Papakonstantinou]

axis tight

its a command.It sets the limits of the axis according to the min and max values of the values that you want to plot.

For example if the maximum y value from the values that you want to plot is 60, the axis tight will force the upper limit of the plot to be equal with 60. Off course it will force all other limits of plot according to the min and max values of the values that you want to plot.

So

ylim([2 inf])

will have the same effect in the upper boundary of y axis as

axis tight

I wanted to give a relative freedom to my plot so I wanted the

axis auto

which does not bound the limits of the plot with my min and max values.

I would not consider this approach to be "automatic". "Automatic" would mean that it happens without you specifically having to set it. For example if something else changed the ydata, then MATLAB would know to set the new limit the way you want.

The solution worked great for me:

limsy=get(gca,'YLim');
set(gca,'Ylim',[2 limsy(2)];

Quick question, what does the 2 in limsy(2) indicate. I feel as if I should know the answer but it is eluding me at the moment.

Thanks!

2nd value from Ylim (i.e it consists of ymin and ymax), so it reports back ymax

No.

You could probably work something up using a listener or two to detect changes to the xdata or ydata and to set() the xlim and ylim as appropriate. I wouldn't bother doing it that way, though.
