How to remove empty space after legend?

22 views (last 30 days)
Can anyone please give me some advice on how to remove the area below the legend.
The code is below, thanks.
C_Span = [4 8 12];
Length_C_Span = length(C_Span);
% standard plot size
x0_d=10; y0_d=10; width_d=675; height_d=width_d/(5/3); % figure default size
%height_d=675;
figure(1);
plot([1 2 3], [1 5 7]);
hold on;
plot([1 2 3], [4 5 8]);
hold on;
plot([1 2 3], [1 5 9]);
hold off;
%grid on;
box on;
for i = 1:Length_C_Span
LegendInfo{i} = ['{\it {\beta}} = ', num2str(C_Span(i))];
end
legend(LegendInfo, 'Location', 'SouthOutside', 'fontname', 'Times New Roman', 'fontsize', 12, 'NumColumns', 3);
set(gcf, 'position', [x0_d,y0_d,width_d,height_d]);

You can adjust the axes height as below (I'm using a red figure so you can see the space beneath the axes here in the online environment):
C_Span = [4 8 12];
Length_C_Span = length(C_Span);
% standard plot size
x0_d=10; y0_d=10; width_d=675; height_d=width_d/(5/3); % figure default size
%height_d=675;
% figure(1)
figure('Color','r');
plot([1 2 3], [1 5 7]);
hold on;
plot([1 2 3], [4 5 8]);
hold on;
plot([1 2 3], [1 5 9]);
hold off;
%grid on;
box on;
for i = 1:Length_C_Span
LegendInfo{i} = ['{\it {\beta}} = ', num2str(C_Span(i))];
end
legend(LegendInfo, 'Location', 'SouthOutside', 'fontname', 'Times New Roman', 'fontsize', 12, 'NumColumns', 3);
set(gcf, 'position', [x0_d,y0_d,width_d,height_d]);
% increase axes height by 0.07 (and decrease the bottom location by same
% amount):
adjustment = 0.07; % change this to what you think looks good
ax_pos = get(gca(),'Position');
ax_pos([2 4]) = ax_pos([2 4])+[-1 1]*adjustment;
set(gca(),'Position',ax_pos)

you can change your lengend location to "northwest" or "Southeast"
legend(LegendInfo, 'Location', 'northwest', 'fontname', 'Times New Roman', 'fontsize', 12, 'NumColumns', 3);

I want it keep outside the plot. I know I can put it inside, there is even an option called "best" which will put it in a proper position inside the plot.
