Thread Subject: Ticks on dual axis ...

I'm plotting dual axis (left, right) and I need to
selectively remove the tick marks from opposite axis or the
plot looks like someone tried to zip together two unequal
zippers.

In other words, I only want ticks on the left hand side of
the plot and NOT the right hand side (and vice versa for
the right had plot).

Is there some kind of 'mirror' option in axes that will
allow this? I can't find anything and the only remaining
option is to export to Adobe and treat/amend the figure as
artwork.

It sounds like you want PLOTYY.

No ... I tired plotyy and found that I had lack of control
over the axis.

All I want is to turn of the ticks on opposing axis! Is
that too much to ask from a plotting routine?

The first output argument from PLOTYY contains the handles of the two axes
it creates; from there, you can use just about any function that accepts an
axes handle to control them. [Performing certain operations (like changing
the limits of one of the axes or zooming one axes) may cause the locations
of the ticks on the two sides to fall out of sync.]

If you have the handles to your axes, modify the YTick and/or YTickLabel
properties of those axes. [I know the URL mentions XTick, but that section
of the documentation talks about the three properties XTick, YTick, ZTick as
a group since the only difference between the three is which axis they
affect.]

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/axes_props.html#XTick

Note that if you want the ticks to be at exactly the same heights on the
left and right sides of the axes, PLOTYY will perform that synchronization
for you -- if you don't want to use PLOTYY, you will need to synchronize
them.

It would be a lot easier on everyone if there was simply a
axis property switch to turn off the ticks on one side,
rather than force the use of an awkward function like plotyy.

Thanks,

Once you have a handle to the Y axis you want, just set its
Ytick property to an empty vector, [].

Of course that would work, but only if it was that straight
forward to get the handle of the specific 'axis' (not the
axes). Indeed, i found it very surprising that tick marks on
the opposite side is not optional as Joe also mentioned. And
plotyy function is not really taking care of different sets
of tick marks occuring at the same axis, as been claimed.
So, only solution left is that we have to arrange tick
spacings such that they overlap, a solution which cannot be
automatized easily..

You just need the axes handle.
So this should work:
[AX,H1,H2] = PLOTYY(...)

Left
set(AX(1),'ytick',[]);
Right one
set(AX(2),'ytick',[]);

Read the previous messages carefully. We are talking about
turning the tick marks off/on on opposing axis for a simple
plot (plot(x,y), e.g. left hand y-axis has ticks and right
hand y-axis does not. At present, then cannot be easily
achieved in Matlab.

Sorry for that.
I don't know if that is what you are trying to do.
But you can turn the Box of the axes to off
So you can have something like.
plot(x,y);
set(gca,'box','off')
so you are going to see only one axes on the left.
set(gca,'YaxisLocation','right');
to move the axis to the right.

Thanks. Your 'solution' seems to work!

If you still want a dual axis plot with the 'box on' you can consider to use a dummy as follows:

% dummy axes for the box and background color
ax0 = axes;
set (ax0, 'Box', 'on', 'Color', 'white', 'XTick', [], 'YTick', []);

% first axes for left y-axis
ax1 = axes ('Position', get (ax0, 'Position'));
set (ax1, 'Box', 'off', 'Color', 'none', 'YAxisLocation', 'left');

% second axes for right y-axis assuming common x-axis controlled by ax1
ax2 = axes ('Position', get (ax0, 'Position'));
set (ax2, 'Box', 'off', 'Color', 'none', 'XTick', [], 'YAxisLocation', 'right');

Now manipulate ax1 and ax2 as you like, the dual axis plot will appear as you expect intuitively without interfering ticks of left and right y-axes.
