@Mikael: Thank you for the kind feedback. You can try Christian's modification to not display negative arrows. See his comment from 05 Jan 2013 for a link. (Disclaimer: I have not tested this code). I'll think about adding this functionality in my next update, but I'll have to put some thought into the best way to implement it.

Adding grid lines has been on my todo list for a while. Hopefully I'll have some time in the next month or two to work on it. Right now, if you want grid lines, you have to un-hide the parent axes (oa.HideParentAxes = 'off') and turn the grid on as usual. Unfortunately, you end up with the parent axes' axis lines, ticks and tick labels as well - it gets kind of cluttered.

@Christian: Thanks for the kind feedback. I'll take a look at your modified code and consider adding it as an option in my next update.

@cpas1940: If you want to change the label rotation, you can access the handles of the labels in oa.hXLabel, oa.hYLabel, etc. Then you can set the 'Rotation' property as well as any other text properties directly. I'm not sure what you mean by 'having the ylabel centered at (0,0)'. If one of the ylabels were located at (0,0) it would no longer be a label on the end of the axis (assuming oaxes is centered at (0,0) and the limits are [-a +b]). If you are talking about having a rotated label be centered around the y axis line, you can play with the 'HorizontalAlignment' and 'VerticalAlignment' text properties of the labels. Here is an example:

oa = oaxes;
set(oa.hYLabel(1),'Rotation',90)
% (The negative-axis label is now rotated by 90 degrees, but not centered correctly)
set(oa.hYLabel(1),'HorizontalAlignment','right','VerticalAlignment','middle')
% (Now it is centered and no longer overlapping the end of the axis line)

Mukilan,

Thanks for the feedback. I could not reproduce your problem exactly, but here is some information that might be helpful:

Your example code is setting the 'XTickLabel', 'FontName', etc. properties of the parent MATLAB axes (the handle returned by gca), not the properties of the oaxes object. (However, your code does directly set the oaxes object's 'XLabel', 'XColor', etc. properties, and you do not indicate any problem with this part of your code). As documented in the oaxes help, upon initialization, the various text properties of the parent axes are copied to the oaxes, but are then independent. Your code will have no effect on the oaxes tick label font properties. To set the oaxes object's tick label font properties, use the following syntax:

set(oa,'TickLabelFontName','Times New Roman','TickLabelFontSize',14,...)

Note that the pertinent property names for the oaxes object all start with 'TickLabel', unlike the MATLAB axes object. See the oaxes help for a complete list of property names. (I'm not sure why I named them that way - if it bugs enough people, I'll change the names to correspond to the MATLAB axes properties). For both oaxes and MATLAB axes objects, you cannot set different text properties for the x and y axis tick labels - the properties affect each axis.

There is a bug in oaxes that in some cases (including the default case) results in the tick labels not being redrawn when the tick label text properties are changed. I will release an update shortly to fix this. For now, the workaround is to force a redraw after changing the tick label text properties using any of the following (where oa is the handle of the oaxes object):

oa.draw
oaxes('draw')
oaxes draw

Your code sets the 'XTickLabel' property of the parent axes, but not the 'XTick' property. I strongly recommend not doing this because it can lead to incorrect tick labels. For example, type xlim([-1 5]) after setting the 'XTickLabel' property as you specified in your example code. Note that the displayed tick labels do not correspond to the values of the ticks. To avoid this, always set both the 'XTick' and 'XTickLabel' properties together, and when changing back to 'auto' mode for tick placement and labeling, make sure both the 'XTicKMode' and 'XTickLabelMode' are 'auto'. See the MATLAB documentation for 'Axes Properties' for more information.
The behavior of oaxes is identical to the MATLAB axes object in this regard. So if you want to put tick labels at specified locations, set both the 'XTick' and 'XTickLabel' properties of the oaxes object, or just set the 'XTick' property and make sure 'XTickLabelMode' is set to 'auto' (the default). Note that the default behavior of oaxes ticks is to mirror the parent axes tick values ('XTickMode' is set to 'parent' by default). So, unlike the tick label text properties, any changes you make to the parent axes tick values are copied to the oaxes ticks. If you set the 'XTick' property to your own values, 'XTickMode' changes to 'manual'. You can also set it to 'auto' to have oaxes calculate the tick placement rather than copy the parent axes. See the oaxes documentation for more information.

Also note that your example code has errors in the final two 'set' statements - where it reads:

set(gca('XTickLabel'),...

it should say:

set(gca,'XTickLabel',...

Nam,

Thanks for the feedback - I'll take a look at it. For presentation-quality graphics, you might want to try using export_fig to save your figures (link: http://www.mathworks.com/matlabcentral/fileexchange/23629 ).
