You could do it with coding / macros. The coding/macro approach would
be something like
1. create MeasureName as an artificial dimension (i.e. create a
table in your script that has MeasureName as its only field, and
populate it with the 3 values via INLINE)
2. create a variable for each Measure that tests if that Measure is
selected or possible (e.g. vSalesIsSelected), using
GetFieldSelections(). Make sure the expression has '=' on the front of
3. in your chart, create the expression for Sales as something like
if(vSalesIsSelected,calculation), so that the expression is always null
when Sales isn't selected (and hence QlikView won't display it).
Similarly define the expressions for the other two measures.
An alternative approach is to design your data model so that the
appropriate table has
a field called MeasureName (which can have values 'Sales','Cost'
or 'Net Revenue') and
a field called MeasureValue, giving the value of Sales, Cost or
Net Revenue as required.
Then, your list box shows MeasureName, and your chart has MeasureName as
one of the dimensions. This avoids the messiness of variables & extra
expressions - at the cost of possibly changing your data model. Pros &
hi Angus thanks for your reply,
what if i wanna do it like what i've described in another discussion http://community.qlik.com/thread/30437
i will have 2 list boxes, 1 list box with the location field and 1 list box with sales, costs and netrevenue
as described in that discussion, sales/costs/netrevenue will be the dimensions
and assuming i have location1 location2 and location3 under the field location
by default there would be 3 sets of bars (sales, costs and netrevenue) and each set of bars will 3 bars that are location-specific...
if i only selected sales and costs, there would only be 2 sets of bars, each set having 3 location bars since i did not specifically select the location to look at
if i only selected sales, there would only be 1 set of bars n the set having 3 location bars since again i did not specifically select the location to look at
if i only selected sales, location2 and location3, there would again be only 1 set of bars. however, this set of bars will only have 2 bars since i only selected 2 locations
sales/costs/netrevenue/location are currently 4 fields in my table...
