how to plot graph of Precision and Recall in Matlab? -

i have 3 values precision , recall follows:

precision = 0.4     recall= 0.45 precision= 0.58     recall= 0.52 precision= 0.6      recall= 0.53 

above values show when precision 0.4 recall 0.45 , vice versa, want plot these results in graph should show increase , decrease in precision , recall values respect each other.

i want show result of these values in single graph should show 3 curves(lines) different colors different representation.

i guessing @ trying achieve honest, possibly looking "hold all" command. if not want achieve, please provide example of plotting single curve, can push in right direction of how expand on that.

figure hold plot(calculate_my_results(0.4,0.45)) plot(calculate_my_results(0.58,0.52)) plot(calculate_my_results(0.6,0.53))
