Problem with 'keeplimits' for dates on figure x-axis

Hi,
I've search for an answer to my question but I still cannot get this to work. I am trying to plot data on a figure with the date on the x-axis. My problem is that the figure extends beyond the x-axis limits, even if I am using 'keeplimits'. The figure keeps showing an x-axis extending from May 11 to Oct 24 instead of the May 20 to Oct 22
t = datetime(2009,05,19) + caldays(1:156);
Ya = plot (t, wtddata(:,1),'-','LineWidth',2);
hold on; Yb = plot (t, wtddata(:,2),'-','LineWidth',2); hold off;
datetick('x','mmm','keeplimits')
Any help would be appreciated.
Thanks

Hi Luc,
I see that you are utilizing the datetime datatype introduced in R2014b. MATLAB picks an optimal set of ticks and labels when you plot a datetime array.
In case - such as yours - when MATLAB's optimal set of ticks is not the most suitable, you may pan and/or zoom the plot to get your desired layout. MATLAB will automatically update the ticks and labels to match the new limits after panning/zooming.
Most importantly, only use datetick when you are plotting dates and times represented in numeric values that are serial date numbers, rather than datetime arrays.

After an answer has been accepted, it is best to ask a new question in a new thread to get a timely response. That being said there is a way to use datetimes and change the Format displayed when you call the plot function. However, to change the location of the ticks on the x-axis you need to use MATLAB serial date numbers:
d = datetime('01-Jan-2015') + days(0:10:50);
y = randn(size(d));
ax = axes;
plot(d,x,'DatetimeTickFormat','MMM');
numMonths = month(between(d(1),d(end)));
xTick = datetime('01-Jan-2015') + calmonths(0:numMonths)
xTick = datenum(xTick);
ax.XTick = xTick;
