add dimension of an array subset

[acewong7]

Hi, everyone. I am studying the array chapter based on a book. Here is a small problem i met, i want to increase the size of the array subset. According to the HELP TEXT, i can do it by putting the crusor at the bottom of the array subset, then resize it by drag down. However, it didn't give me the tool to resize this array subset when i put my crusor at the edge of the bottom. Also i have tried right click on the array subset to see if there is an option to add the size, still not. Can anyone tell me why this happened? Thanks

you only have a 1d array, if you had a 2d...it auto builds

You can only have one array subset per operation (that's why this idea exists!) As mentioned above, the node expands for each dimension of the array.

... and yes, I agree that the context help drawing is misleading, because we cannot get a resize tool as shown.
