Adding graphs in a window embedded in a panel

Your code seems to suffer a bit from $-confusion. The following code snippet works here and hopefully illustrates how to do it:

You can also pass a custom name via /N. The idea is that you build the window path as you go with always the same pattern.

The problem is that subwindow paths do not support string constants. Assuming you have a string constant like this:

It seems to be a parsing issue- the compiler doesn't know where the string expression ends. This compiles:

I'm not really certain what the compiler is doing when it parses the expression, but I find it's pretty common that you need to help the compiler parse an expression by adding some parentheses. In this case, it makes it clear that the string expression that the $ operator applies to is just the string constant.

@Howard: Thanks for pointing the error out.

Our coding conventions [1] have the entry "Don’t mix $ with other expressions as it makes the code too hard to read". As both the compiler and humans can easily get into trouble at complex expressions with $.

Thanks all for the information and suggestions.

Yes, I had a string constant (StrConstant kPanelName = "MyPanel") which I used to name the base panel and were trying to embed subwindows in it. It would be better if Igor could use a string constant to refer a subwindow in the way I was trying to do because that bit of code looks simple and potential to work.
