matlab中折线图代码关于向量长度必须相同的错误修改问题

x = 1:1:12; % x轴上的数据

% 给每个向量填充NaN，使其长度与最长的向量相同

% 绘制折线图
plot(x, a, '-*b', x, c, '-or', x, d, '-*b"', x, e, '-*b^2', x, f, '-*b');

axis([0, 12, 0, 200001]); % 确定坐标轴和y轴范围
set(gca, 'XTick', [0:1:12]); % 设置x轴范围为1-12，间隔为1
set(gca, 'YTick', [0:2000:20000]); % 设置y轴范围为0-20000，间隔为2000

legend('花菜类', '花叶类', '辣椒类', '茄类', '食用菌', '水生根茎类'); % 在右上角添加标注
xlabel('季度'); % 设置x轴坐标描述
ylabel('总销售量'); % 设置y轴坐标描述
