xticks not looping correctly?

Hello,

I've created a series of subplots but I'm running into an issue where each suplot's x axis ticks are off. So where subplot 2 should be 31-60, subplot 3 should be 61-90, etc. But instead it looks like this the screenshot I've attached.

Here is the code I've written:

figure;
RTkeys=(SRTT.RT(find(SRTT.Correct_Key==1)));
numRTkeys=1:numel(RTkeys);
x=length(RTkeys)/7;
plotNames={'1', '2', '3', '4', '5', '6', '7'};
sgtitle('Key 1 Reaction Times','fontsize',16,'fontweight','bold');

for k = 1:7
    subplot(7,1,k);
    plot(numRTkeys((1 + (k-1)*x):k*x), RTkeys((1 + (k-1)*x):k*x),  '-o');
    title(sprintf('Block %s', plotNames{k}))
    xlabel('Key Occurance');
    ylabel('Reaction Time');
end

I assume it has to do with the line:

plot(numRTkeys((1 + (k-1)*x):k*x), RTkeys((1 + (k-1)*x):k*x),  '-o');  

Does anyone have any ideas?

Thank you in advance!
