MATLAB: Plotting with dates and timesteps

dateticktrading analysis

Here is part of my script:
%%Parameters
StartDate           = '26-Jun-1992';
EndDate             = '26-Jun-2012';    
TimePlotSteps       = 200;              
data = xlsread('StockPricesClean(1).xlsx');
%%split data
dates      = datestr(data(:,1) + datenum('30-Dec-1899'));
data(:,1)  = datenum(dates);
StartI              = find(data(:,1) == datenum(StartDate));
EndI                = find(data(:,1) == datenum(EndDate));
Data.Dates.numb     = data(StartI:EndI,1);
Data.Dates.str      = datestr(Data.Dates.numb(:,1), 'dd/mm/yy');
Data.Closing        = data(StartI:EndI,5);
clear data
TradeSignal(1:length(macdvec),1)=0;
% Create x-axis vector
x=1:length(TradeSignal);
% Plots with dates
figure(2)
subplot(311)
plot(x,macdvec,'r',x,nineperma)
set(gca, 'XTick',1:TimePlotSteps:length(x), 'XTickLabel',Data.Dates.str)
xlim([0  x(end)]);
title('Trading signals on MACD')
If I set my Timeplotsteps to anything other than '1' the x-axis only runs up to july 1992. however if i keep timeplotsteps to '1' the x-axis runs up to july 2012 as it is supposed to but the x-axis looks terrible due to the small steps on the x-axis. How can I solve this (I am a beginner in Matlab so simplicity is appreciated!!)
thanks!

And remember, the number of elements in XTickLabel must be the same as the number of elements in XTick.
