Just wondering if there's a way to graph the data points listed in bal_1 in different colors so as to differentiate one row from another. The current code generates an image like the one you see below, and I'd just like to add different colors so I can distinguish one row from another. For instance, one row to be blue, the next to be red, etc.
bal_1 = [0.9445 0.9274 0.9379 0.8823;
0.9407 0.9348 0.9325 0.9313;
0.9185 0.9296 0.9195 0.9391;
0.9462 0.9294 0.9409 0.9426];
bal_t1 = transpose(bal_1); %transpose of all data for anova1 testing
balloons_1 = {'#2' '#3' '#5' '#9'};
x{1} = 1:size(bal_t1,2);
figure(2)
plot(x{1}, bal_t1, '+b') % Plot Matrix
axis([0 5 0.875 1]) % Set Axis Limits
set(gca, 'XTick',x{1}, 'XTickLabel',{'#2' '#3' '#5' '#9'}) % Set Tick Labels
xlabel('Balloon Number','FontSize',10,'FontWeight','bold')
ylabel('Pressure Change Rate (kPa/min)','FontSize',12,'FontWeight','bold')

Just changing the plot command a bit may work for you:
plot(x{1}, bal_t1(:,1), '+b',x{1}, bal_t1(:,2), '+r',x{1}, bal_t1(:,3), '+g',x{1}, bal_t1(:,4), '+m')
