MATLAB: Scatter plot with conditional coloring

I have a large data matrix with 5 columns. 5th column contains many zeros. I want to do scatter(data(:,4),data(:,5)) and set a different color for points/rows where value in 5th column is zero.

I will then draw scatter plot of different columns but with same condition i.e. different color where values in 5th column are zeros.

You can easily set the different color-flag as a fourth parameter in a function:

scatter(d(:,4), d(:,5), 7, d(:,5)==0);

Here d(:,4) and d(:,5) are the coordinates of points, 7 is the size of the point, and d(:,5)==0 is the color-flag (for different values of d(:,5), different colors are chosen).
