how plot complementary cumulative density function (CCDF) of data points?

suppose i have data points as:

 a=2.3; 
 b=5.3;
 n=2000;  % number of data blocks
 data=a+(b-a)*rand(1,1000); % data points
 x=[1:.1:7]; % x-axis

How to plot the Complementary Cumulative Density Function (CCDF) of this data for such 2000 data blocks ? Any help.

If you have the stats toolbox:

 ecdf(data,'function','survivor')

will plot the CCDF.
