How to remove tick label from y axis

Hi,

I have a y axis with labels on the y axis -1 -0.5 0 0.5 1 1.5 2 2.5 3 3.5 I want to remove the first origin label -1. How do I do that?

I have done it with the X axis by the following: set(gca,'XTick',x(2:end)); set(gca,'XTickLabel',x(2:end),'fontsize',14);

but when I try with the y axis I get an error message as follows:

Error using set Values must be monotonically increasing

regards James

Does this do the trick for you:

plot(1:10)
set(gca,'YTickLabel',[]);

Thanks. Just what I needed.

What is the reverse operation to this?

@__init__.py You can set up tick labels to be "auto" or whatever custom labels you want with the yticklabels function.

help yticklabels

 YTICKLABELS Set or query y-axis tick labels
    YTICKLABELS(labels) specifies the y-axis tick labels for the current
    axes. Specify labels as a cell array of character vectors, for example,
    {'January','February','March'}. This command will also set both
    YTickMode and YTickLabelMode to 'manual'.
    
    yl = YTICKLABELS returns the y-axis tick labels for the current axes.
    
    YTICKLABELS('auto') lets the axes choose the y-axis tick labels. Use
    this option if you set the labels and then want to set them back to the
    default values. This command sets the YTickLabelMode property for the
    axes to 'auto'.
    
    YTICKLABELS('manual') freezes the y-axis tick labels at the current
    values. This command sets the YTickLabelMode property for the axes to
    'manual'.
    
    m = YTICKLABELS('mode') returns the current value of the tick labels
    mode, which is either 'auto' or 'manual'. By default, the mode is
    automatic unless you specify tick labels or set the mode to manual.
    
    ___ = YTICKLABELS(ax, ___ ) uses the axes specified by ax instead of
    the current axes.
    
    YTICKLABELS sets or gets the YTickLabel or YTickLabelMode property of
    an axes.
    
    Unlike setting the YTickLabel property directly (which will have no
    effect on the YTickMode), YTICKLABELS will set the YTickMode to
    'manual' in addition to setting the YTickLabelMode properties to
    'manual'.
    
    If you specify fewer labels than there are tick values, YTICKLABELS
    will append blank labels so the number of labels matches the number of
    tick values.
    
    See also YTICKS, XTICKLABELS, ZTICKLABELS, THETATICKLABELS,
    RTICKLABELS.

Hello James, I tried your problem statement in the following example.

fh = plot(-10:10);
axis = get(fh,'Parent');
yTick = get(axis,'YTick');
set(axis,'YTick',yTick(2:end));

It did not give the error while setting the values as the axis YTickLabels get automatically updated when you update the YTick values.

Can you give more details of the scenario what you are facing?
