Hi I try to make a boxplot for hourly values of data for differnt months. So in one diagramm I have a boxplot for January Feb March and so on... As the amount of hours of each month vary boxplot always gives me an error.

code

```
X=[N11(:,9) D12(:,9) J1(:,9) F2(:,9) ];
G=[1 2 3 4];
boxplot(X,G)

```

size of data:

```
J1=744

F2=624 

D12=744

N11=720

```

thanks matthias
