Colour legend for scatter plot

I created a 2D scatter plot with the vectors X, Y and Z and following code

scatter(X,Y,50,Z)

So that I would have X and Y plotted against one another, and Z would be represented as the graded colour of each marker. It worked fine, but I need a legend that shows the range of Z values represented by the range of marker colours. How do I make this?

Ah not to worry I have found the answer. You just type
