Hey,

I have to scatter 2 different vars of 2 measurements like in the picture below. The marker symbol describes the variable which is plotted, the color is for different measurements. How can I create two legends, one for the symbol, one for the color?

figure(1);
hold on
y1 = scatter(measurement1.n, measurement1.var1, 'ro');
y2 = scatter(measurement1.n, measurement1.var2, 'rv');
y3 = scatter(measurement2.n, measurement1.var1, 'bo');
y4 = scatter(measurement2.n, measurement1.var2, 'bv');
