I have a column in a table called city, This column has more than 100 distinct values. using city column as a dimension,
when i create a stacked bar chart, since there are many of them(cities). I cannot see much of that in the chart and it gets so messy.
is it possible to break a dimension with 100 possible values into 5 groups of dimensions each has 20 values?
Thanks for your help in advance.
Go to Solution.
I think your way would be the best one. Like that, you do not need to hardcode it in the script and if any new groups are going to be added you will add them into your database
You can always hardcoded in your script by using nested if statement or PICK() function will solve it too.
if(mixmatch(City,'New York'),'Group 3',
'Group 4'))) as City_Groups
'Group 1', 'Group 1','Group 2','Group 3')
as City Groups
Certainly is possible.
First you need to define the rules as to which city goes into which group.
Thanks for your instant response.
would you please explain more. how can i set that rules? in dimension tab?
Given the amount of cities I would recommend doing this in the script. I would create a new table with City and Group. you then join this table to the table where you city is stored.
Load * inline [
Chicago, Group 1
NY, Group 1
Miami, Group 2
Orlando, Group 2
you can then use your Group field in your chart.
In script using pick function divide these cities into 5 groups, give it name as Cities_Grouped.
In your chart: Dimensions->Edit Groups->New->Drill Down and select Cities_Grouped and Cities.
When you go to your chart you should be first presented with Cities_Grouped, clicking on any of the Cities_Grouped will then drill down to your 20 Cities in this group.
Dear Friend, would you please do it on a sample? i am not actually good at scripting.
I uploaded the sample.
I'd like to see what percentage of each city population lives in different temperature conditions.
the table has just 3 columns.
dimension: City, Temp
Type of chart: Stacked Bar Chart
Check this file,
dril down with Temp->Cities
i.e once you click on any of the bar you will get citites having that temperature.
Let the city be the first dimension. since the number of cities are many, i like to break down them into 2 groups.
i don't think that's the answer of my question.
thanks by the way.
If so you will have to add one more column to group your cities...will it be okay?
Look at the answer of TerezaGr, a couple of post above your answer. what do you think?
