Try this:

allData = xlsread(filename);
column1 = allData(:, 1);  % Extract column #1
column2 = allData(:, 2);  % Extract column #2
column3 = allData(:, 3);  % Extract column #3
plot(column1, 'rd-', 'LineWidth', 2, 'MarkerSize', 8);
hold on;
plot(column2, 'go-', 'LineWidth', 2, 'MarkerSize', 8);
plot(column3, 'b*-', 'LineWidth', 2, 'MarkerSize', 8);
