Volume by price formula

Hello,
reading the manual I came across the Profiles section and more to the point to this formula:

Volume by price graph (daily chart)
PlotProfile("volume", 0, 1, 100, colorRed, colorRed, OperationSum);

Which is really helpful in highlighting support and resistance. However, If I'm reading it right, there is a no way to weigh in more recent price/volume action to this graph. So if a stock has been trading thinly in the past year I won't see a bar for that price. Is there a way to change parameters so that I can see the price/volume action for instance for the past 6 months ? Or any other combination ? What parameters should be changed ?
Thanks a lot !

You can for example display volume profile for each year by typing:
PlotProfile("volume", year() != ref(year(), 1), 1, 100, colorRed, colorRed, OperationSum);

Note that the first parameter is a formula and you can add any QS formula you want.
Example:
PlotProfile("close - open", year() != ref(year(), 1), 1, 100, colorRed, colorRed, OperationSum);

At first I didn't see any data because the bars were at the beginning of the year. Thanks !
