• 我尝试绘制控制图图 ， 并将 * 网格添加到每个图 *。但是如果我尝试绘制图表：例如xbar和r图表，使用controlchart()我只能得到最后一秒的图（r图表），带有网格。
  我的麻烦： 如何绘制两个情节和一个数字不分开，例如，两个子情节？

我想用网格绘制两个CCarts，代码不工作：

% Create figure
figure;

% Subplot 1 for the first control chart ('xbar' chart)
subplot(2, 1, 1);
st1 = controlchart(data, 'charttype', {'xbar'});
grid on;
grid minor;

% Subplot 2 for the second control chart ('r' chart)
subplot(2, 1, 2);
st2 = controlchart(data, 'charttype', {'r'});
grid on;
grid minor;

型
这段代码也不行：

st1 = controlchart(data, 'charttype', {'xbar','r'});
grid on;
grid minor;
