MATLAB: Marker and Line in legend in matlab plot

legendlinesmarkersMATLAB

Hi, I am plotting the experimental data and fitted line using matlab plot. The legend command shows the markers (data points) and line (fit) as a separate legend entry. However, I am interested to obtain the marker and line in a single legend entry so that the total number of legend entries could be reduced from 8 to 4 in my case. Hence, I would like to ask your assistance which could be useful for my plot. Thank you.

Create additional line objects that combine the attributes, such as

LH(1) = plot(nan, nan, '*-r');
L{1} = 'tadpoles';
LH(2) = plot(nan, nan, '^:g');
L{2} = 'cheese';

Then legend() those

legend(LH, L)

According to the Walter answer on above my problem solved easily using :

L(1) = plot(nan, nan, 'b-');
L(2) = plot(nan, nan, 'r--');
legend(L, {'first case', 'second case'})

The easiest way is to create a fake graphics object with coordinates NaN, NaN but with the appropriate shape and color and line attributes; do this repeatedly for each entry and record the handles. Then legend() against those handles with appropriate text in a cell array.

For example,

L(1) = plot(nan, nan, 'b.', 'MarkerSize', 5);
T{1} = 'Urmar Tanda';
L(2) = plot(nan, nan, 'b*', 'MarkerSize', 5);
T{2} = 'Pattamundai';
L(3) = plot(nan, nan, 'kv', 'MarkerSize', 8);
T{3} = 'Lakheri';
L(4) = plot(nan, nan, 'k^', 'MarkerSize', 8);
T{4} = 'Sirsa';
legend(L, T)
