First day in QlikView and I'm having an issue with a bar chart.
The chart has 3 expressions and 1 dimension. There is an associated listbox for the expressions. If the user does not make a selection, than all three expressions are displayed. If the user selects an item, the intention is for them to only see 1 bar per dimension.
My dimension is Month (Jan-Jun)
My Expressions are Digital Revenue Print Revenue and Expense.
When the user chooses "Expense", the chart displays properly.
When the user chooses either of the other 2 expressions, the chart displays a bar for the selected expression and then a second bar for the same value, in the color assigned to "Expenses". This doesn't happen for the month of Jan, but does for all other months. I've checked the data tables and they're clean. I'm thinking I have a setting wrong somewhere, any ideas?
Take a look at the design blog post by Henric Cronstrom...
Synthetic keys should be resolved in the data model as they can/will give you spurious results in your app. There are a number of resources to help you, including the Qlik training courses.

Thanks everybody! Since ultimately, I will be working with very large data sets, I don't think a Link table will be viable due to the number of combinations involved.
I'm going to look into consolidating my data and try to figure out how to split the display of the data in my chart, somehow.
Yes it is, that is the synthetic table that qlikview will automatically generate for you.
You can either join or concatenate tables to get rid of them, if they are related values.
If not, you can rename fields if they are distinct sets of values and that will solve the problem as well.
Yeah, I am stuck. Here is my basic structure, I have 3 tables which have identical columns, but different data. I have this set up to allow each set of data to feed a separate expression in charts.
I have three more tables which translates values/consolidates data from each of the data tables into higher-level views
I have a Month table, just to force a custom sort on the Month variable.
If I rename the fields from each of the data tables, they will no longer tie to the consolidation tables.
If I consolidate the data tables, I can't use the 3 sets of data (based on account type, for now) as separate expressions, at least I can't figure out how to do it.
I think you should invest more time in theory
The best way i think is to have all the 3 measures (in one row) in a fact table if this is possible. Read something about scripting, concetenation, joins, synthetic keys...
Data model is at least so or more important as a visualization layer in an app.
Do you posses basic knowledge of BI theory?
