How to plot data in different colours depending on numeric condition of non plotted data.

I am plotting a large number of points and wish to be able to distinguish between them using different colours based on a criteria included within the dataset but not plotted upon the figure.
From my dataset I want to plot all the points in column 8 against all the points in column 6 with the colour of the plotted point dependent on the value in column 17. For example I want to plot the point in red if the value in column 17 is greater than 125, in blue if the value in column 17 is greater than 100 and so on.
I have tried using a for loop but am not having much success. Any help would be much appreciated.

Use scatter(). It can take different colors for each marker. If you want lines between the markers, call plot() first, then "hold on", then scatter().

Perfect:
The above code works for me. I replaced y(k) in the if loop with my third variable.
Thanks a lot!
