Hello
I have assigned color to my figures. legend box includes info about what color covers what range of data. when i change the font size, it only changes the size of the text inside of the legend box (ex: 0-100 cd) . please see the attachment. how can I change those dots to be more legible ? thanks !
L1 = (z > 0) & (z <= 100);
L2 = (z > 100) & (z <= 1000);
figure(1)
scatter3(x(L1), y(L1), z(L1), 'b', '.')
hold on
scatter3(x(L2), y(L2), z(L2), 'c', '.')
hold on
lgd =legend('0 - 100 cd/m2 ', '100 - 1000 cd/m2')
lgd.FontSize = 14;

YOu have to increase the marker sizes while plotting the data.
A = rand(10,3) ;
plot(A,'.','MarkerSize',10)
lgd = legend ;
lgd.FontSize = 14;

Thank you!
for some reason its not working for me. giving me this error:
Error using matlab.graphics.chart.primitive.Scatter/set
There is no MarkerSize property on the Scatter class.
Error in scatter3 (line 112)
set(h,'Parent',parax,'XData',x,...
and thats what I have:
L1 = (z > 0.001) & (z <= 5);
L2 = (z > 5) & (z <= 15);
figure(1)
scatter3(x(L1), y(L1), z(L1), 'b', '.', 'MarkerSize',10)
hold on
scatter3(x(L2), y(L2), z(L2), 'c', '.','MarkerSize',10)
