I would like to create a scatter plot in MATLAB using three sets of data. X,Y and c. X and Y are to be their respective axis plots but c holds information (integer values) on each scatter points classification. I wish to make each classification plot as a separate colour....

## Color scatter plot in Matlab according to 0 or 1 value

matlab,colors,matlab-figure,scatter-plot,scatter
I populate a grid data=zeros(n,n); with 0's and 1's (could also be thought of as an adjacency grid, if you'd like). I just want to plot the grid with colors according to whether the value at that point is 0 or 1. For example, scatter(1:n,1:n,data); It gives me the error:...
