Why is it referring to each seperate datapoint in the legend?

So I am plotting two variables seperately on the same plot, in which each variable is a 26x23 matrix. So it plots 23 observations for each of the 26 features along the x-axis.
figure;
plot(acuteEdgeBC1, 'r*'); hold on;
plot(chronicEdgeBC1, 'bs');
legend('Acute', 'Chronic');
The plot looks fine apart from the legend, as it sees each datapoint from both plots as a seperate thing to note in the legend. So when I try making a legend the way I have done above, 'Acute' and 'Chronic' labels are both assigned to a red star. If I just specify that I want a legend without labels, it shows all the datapoints on the legend, as shown below:

What I would like is a red star assigned to 'Acute' and a blue square assigned to 'Chronic'. How can I do this? Any help would be greatly appreciated- thanks!

Always use object handles.
figure;
ph1 = plot(acuteEdgeBC1, 'r*'); hold on;
ph2 = plot(chronicEdgeBC1, 'bs');
legend([ph1(1),ph2(1)],'Acute', 'Chronic');
