matlab 如何将零值图例显示为图例中的一条线？

下面的例子显示了以下向量的条形图：

% % For Phi/Psi = +/-10
CoverageArea_mean_10 = [84.4735,21.1779,6.4247,2.1416]; 
CoverageArea_min_10 = [98.5128,21.1779,6.9007,2.1416]; 
CoverageArea_max_10 = [70.1963,19.0363,5.9488,2.1416];
% For Phi/Psi = +/-40
CoverageArea_mean_40 = [0,4.5211,2.3795,0]; 
CoverageArea_min_40 = [92.5640,21.1779,6.9007,2.1416]; 
CoverageArea_max_40 = [0,0.4759,0.2380,0];

如下所示

问题是有一些零值，我需要在图例上将它们表示为一条线。如何修复它？*

预期结果：

%% Plotting the coverage area
x = [15,30,45,60];
figure
COVERAGE = [CoverageArea_min_10;CoverageArea_mean_10;CoverageArea_max_10];
COVERAGEAREA = [COVERAGE(:,1)';COVERAGE(:,2)';COVERAGE(:,3)';COVERAGE(:,4)'];
bar(x,COVERAGEAREA);
xlabel( 'Semi-angle at half power, \Phi_1_/_2 (°)' );
ylabel('Coverage area (m²)');
BarNames = {'min','mean','max'};
legend(BarNames,'Location','best');
grid on;
figure
COVERAGE1 = [CoverageArea_min_40;CoverageArea_mean_40;CoverageArea_max_40];
COVERAGEAREA1 = [COVERAGE1(:,1)';COVERAGE1(:,2)';COVERAGE1(:,3)';COVERAGE1(:,4)'];
bar(x,COVERAGEAREA1);
xlabel( 'Semi-angle at half power, \Phi_1_/_2 (°)' );
ylabel('Coverage area (m²)');
BarNames = {'min','mean','max'};
legend(BarNames,'Location','best');
grid on;
