I've got a problem that I'm struggling with, to which I suspect there is a fairly simple solution.

I have a data set in array form, where each data point has an X coordinate, a Y coordinate and a magnitude. I'd like to plot this in two ways:

Firstly with each point as a 'binary' value, where the magnitude is either 1 or 0, represented as a black dot or blank space in the correct position.

Secondly with each point as a colour, depending on the (now 'non binary') magnitude.

Any help would be greatly appreciated!

Take a look at the SCATTER function.
