从一个 N x 3 矩阵中，第三列中的值只有 4 个值 1、2、3 和 4，我必须创建一个条形图以及一个显示每行（第二列值）增长率的线图。第一行值称为“温度”，第二行值称为“生长速率”，第三行值称为“细菌类型”
截至目前，当删除第三列中具有四个值之一的行时，我的线图不起作用。矩阵可能看起来像这样

我的代码如下，数据为矩阵（双）
function dataPlot(data)
%1xN matrix with bacteria
A=data(:,3);
%Number of different bacterias is counted, and gathered in a vector
barData = [sum(A(:) == 1), sum(A(:) == 2), sum(A(:) == 3), sum(A(:) == 4)];
figure
bar(barData);
label = {'Salmonella enterica'; 'Bacillus cereus'; 'Listeria'; 'Brochothrix thermosphacta'};
set(gca,'xtick',[1:4],'xticklabel',label)
set(gca,'XTickLabelRotation',45)
ylabel('Observations')
title('Destribution of bacteria')
%The data is divided into four matrices based on the four different bacterias
%Salmonella matrix
S=data;
deleterow = false(size(S, 1), 1);
for n = 1:size(S, 1)
%For column condition
if S(n, 3)~= 1
%Mark line for deletion afterwards
deleterow(n) = true;
end
end
S(deleterow,:) = [];
S=S(:,1:2);
S=sortrows(S,1);
%Bacillus cereus
Ba=data;
deleterow = false(size(Ba, 1), 1);
for p = 1:size(Ba, 1)
%For column condition
if Ba(p, 3)~= 2
%Mark line for deletion afterwards
deleterow(p) = true;
end
end
Ba(deleterow,:) = [];
Ba=Ba(:,1:2);
Ba=sortrows(Ba,1);
%Listeria
L=data;
deleterow = false(size(L, 1), 1);
for v = 1:size(L, 1)
%For column condition
if L(v, 3)~= 3
%Mark line for deletion afterwards
deleterow(v) = true;
end
end

%Mark line for deletion afterwards
deleterow(q) = true;
end
end
Br(deleterow,:) = [];
Br=Br(:,1:2);
Br=sortrows(Br,1);
%The data is plotted (growth rate against temperature)
figure
plot(S(:,1), S(:, 2), Ba(:,1), Ba(:, 2), L(:,1), L(:, 2), Br(:,1), Br(:, 2))

谁能帮我修复它，所以当我在第三列中有一个没有例如 2 的矩阵时，它仍然会正确绘制吗？
我确实知道如何正确过滤它，并将该过滤应用于“数据”，所以唯一的问题是绘图时出现的错误代码。
错误是；
警告：忽略额外的图例条目。
> In legend>set_children_and_strings (line 643)
In legend>make_legend (line 328)
In legend (line 254)
In dataPlot (line 82)
In Hovedscript (line 153)
从主脚本运行此函数时，矩阵按增长率（第二列）排序并仅过滤要分析的第三行值 1、3 和 4。过滤是通过另一个函数完成的，提前完成，新的“数据”看起来像这样。

再一次，条形图工作得很好，但即使只使用其中的 3 个，它也显示了所有 4 种细菌，问题出在线条图中，图中没有显示一条线。
