I am creating a heat map where the x-axis is a datetime when a measurement was taken. I have about 100 times when data was recorded. When all 100 ticks show up on the x-axis, its not legible so I want to only display time labels for every 10th measurement. I have tried using
ax = gca;
ax.XDisplayLabels = [date(1:10:end)];
But I get the error message "'XDisplayLabels' vector must contain the same number of elements as the 'XDisplayData vector'".
How do I map all 100 columns of data but only display every 10th xtick label?
