Statistical plots
You can create three types of statistical plot:
® scatter plot
® bar chart
® histogram.
Statistical plots are drawn from data you have stored in a real matrix. A
quick way to enter a matrix is to use Matrix Writer. (Matrix Writer is
described in chapter 8, “Vectors, lists, arrays, and matrices”). You then
store the matrix in a variable and refer to that variable when plotting the
data.
Only one data matrix can be plotted at one time (although you can
consecutively plot different data matrices to superimpose one statistical
plot over another).
The last data matrix used to draw a statistical plot is stored in a special
system variable called sigma data (labelled XDAT on the screen).
