how can i show the output of 2 clusters in one plot?

I have two clusters of data each cluster has x,y (coordinates) and a value to know it's type(1 class1,2 class 2)I have plotted these data but i would like to split these classes with boundary(visually). what is the function to do such thing. i tried contour but it did not help!

You could use the plot function. Use "hold on" after you plot the data points so the line/curve doesn't blow away your scatterplot. You could also plot each class in a different color. You could use the convex hull of the points and then plot that, or you could use plot() or line() to place a line between the clusters to divide/separate them.
