Since, this is a histogram, you won't be able to perform any calculation in the this particular chart. You have two options
1) Create a bar chart with your own buckets
2) Modify the script to create a new price field which already exclude the outliers. something like this
Left Join (Table)
LOAD Stdev(price) as StdevPrice,
Avg(price) as AvgPrice
If(price > AvgPrice - 3*StdevPrice and price < AvgPrice + 3*StdevPrice, price) as new_price
DROP Table Table;
I add a description in the data load editor
as hard coding this time. ---then I will change all the graph
but is there any way, I do not change loading data, but only use if() function to limited the data rang for the specific graph on dashboard? at the Data- Fields--prise--Field.
or should I create a variable in the dataset excluding this number (which may mean, if n>4000 then change it to 0)?
