Thread Subject: Missing values

Hi Friends,

Here is an example of a simple plot code with missing values between 2 and 8 on x-axis and corresponding y-values.
x=[1 2 8 9];
y=[2 3 4 5];
plot(x,y);
set(gca,'xtick',x);

when i plot it interpolates between 2 and 8 on the x-axis. Is there a way to delete the gap between 2 and 8? i.e. irregular xlabel and x-ticks? In other words, i just want to plot 1,2,8,9 data points on x-axis instead of 1,2,3,4,5,6,7,8,9.

I deal with large data sets and i have several such gaps in my data set. I don't need to plot the missing values. But i dont want monotonically increasing x-axis either. Please help me if you have any idea.

Cheers

x=[1 2 nan 8 9];
y=[2 3 nan 4 5];
plot(x,y)
