Can I hide data fields in a Chart?

I have a Bar/Line Chart with two data fields. Field #1 is displayed as a bar,
Field #2 a line. I would like to allow the user to choose via a parameter if
the line is displayed.
I tried the following expression for the Field:
=iif(Parameters!ShowTrend.Value=True,Fields!Trend.Value,False)
But rather than hiding the line, it makes all values zero with the line
still showing.
Is there some way to hide the line?
Thanks.You may want to try:
=iif(Parameters!ShowTrend.Value=True, Fields!Trend.Value, Nothing)

But why don't you try a dynamic series grouping and filter those series
groupings that you don't want show (the Grouping&Sorting dialog for every
chart grouping has a filter tab where you can define expressions to filter
data). This should also take care of the chart legend issue.
