I am plotting temperature against time in two conditions (wind and no wind). In total I have 3 different thermometers, therefore the plot will contain three lines for the no wind condition, and 3 lines for the wind condtion. I want to customize my legend so that it appears like this:

No wind: (line) TCosinuss, (line) Tty, (line)TFastFocus (line)

Wind: (line) TCosinuss, (line) Tty, (line)TFastFocus (line)

This is what I have so far:

hlegend = legend([nw_Cosinuss nw_Tympanic nw_Fastfocus w_Cosinuss w_Tympanic w_Fastfocus], 'T_C_o_s_i_n_u_s_s No Wind', 'T_t_y No Wind', 'T_F_a_s_t_F_o_c_u_s No Wind', 'T_C_o_s_i_n_u_s_s Wind', 'T_t_y Wind', 'T_F_a_s_t_F_o_c_u_s Wind', 'Location', 'SouthOutside', 'Orientation', 'Horizontal', 'FontSize', 15);

hlegend.NumColumns = 3
