Also, use it as Field = {‘$(MyTextVariable)’} If your variable should be used as a search string, use it as Field = {$(MyVariable)} If your variable is text, using a Set Expression, using Set Analysis feature, we can pre-define the data to be displayed in our charts. Syntax & Examples Here, we can tell our object (chart / table) to display values corresponding to various sets of data (e.g. a pre-defined time-period, we define the fields that will play in our set expressions. All of these field-value definitions will be encolsed in less-than and grater-than symbols (). The syntax is FieldName = {FieldValue}. If Fi, we have created a set of data which we want to use. In a similar fashion, What is Set Analysis QlikView has feature called SET ANALYSIS that provides us a way to add this context. Set analysis predefines the SET OF DATA that our charts / tables use. So, whe need to add the Set portion of the expression.: o This portion goes just after the first parenthesis, Year = {2010}>} Sales) 5. You can use variables instead of the hardcoded Field Value: If your variable is a number, Year = {2010}>} will give you a record set based on the current selections where Region is equal to South or North and Year is equal to 2010. 4. Your final expression should look similar to: Sum({$, you can create calculations to use them as Field Values: Year = {$(=Max(Year))} It is just as if you would use a variable (described above), you can go on to compse the expression. If you want to Sum the Sales amount, you need to define what you want your expression to return. A good method to get it right would be to answer the following questions first: o What field will I use in my expression? (For example: ‘Sal, you should enclose it in single quotes. If you want to use a search string as the FieldValue, you would start with something like: o Sum(Sales) 3. Then
