How can i display Top 3 values for a particular field in pop up for all the bars in that barchart.
I have created a bar chart with following dimensions and measure:
Country and Value
Now in pop up for all the countries I want to display top 3 countries with highest value i.e. if top 3 countries by value are USA, UK, Japan.... even for Brazil it should show USA, UK, Japan in order ... for all countries.
It is one of the parameter of Rank function, which is mode. For more details see the below content from qlikview help.
You can also search on community for the same for better understanding.
rank([ total ] expression [ , mode [, format ] ])
Evaluates expression, compares the result with the result of the other rows containing the current column segment and returns the ranking of the current row within the segment. For bitmap charts, the current column segment is defined as it appears in the chart's straight table equivalent (Actually all QlikView charts have a straight table equivalent with the exception of the pivot table which has a more complex structure).
If the chart is one-dimensional or if the expression is preceded by the total qualifier, the current column segment is always equal to the entire column. If the table or table equivalent has multiple vertical dimensions, the current column segment will include only rows with the same values as the current row in all dimension columns except for the column showing the last dimension in the inter field sort order.
The ranking is returned as a dual value, which in the case when each row has a unique ranking will be an integer between 1 and the number of rows in the current column segment.
In the case where several rows share the same ranking, the text and number representation can be controlled as follows:
The second parameter mode specifies the number representation of the function result.
If all ranks within the sharing group fall on the low side of the middle value of the entire ranking, all rows get the lowest rank within the sharing group. If all ranks within the sharing group fall on the high side of the middle value of the entire ranking, all rows get the highest rank within the sharing group. If ranks within the sharing group span over the middle value of the entire ranking, all rows get the value corresponding to the average of the top and bottom ranking in the entire column segment.
Lowest rank on all rows.
Average rank on all rows.
Highest rank on all rows.
Lowest rank on first row, then incremented by one for each row.
Now, I have a stacked chart which shows country and Division as Dimensions with division stacked up in country. I want to show in pop up, Top 3 Countries for that particular division when I hover over that division in that country, even though That country is not in top 3. Right now with the formula we have I am able to display top 3 countries by total value but not by division.
