How to return single string value in calculated field using Tableau data from python and present it on new sheet of Tableau as Text value.
For example, Data contains lists of cities and population of city. These are represented in graph in Tableau. We would like to find city having maximum population. Python code is written using max function. The python code is returning correct value to tableau, however there are multiple rows returned to tableau while I need only single value.
Incase we are using label for returning maximum population in Tableau, it doesn’t return any value if we are not passing parameters in row and column field which are used in python code.
Below python code is used to find maximum population in city:
SCRIPT_STR("
city_list = _arg2
population_list = _arg1
highest_population = max(population_list)
ind = population_list.index(highest_population)
city_name = city_list [ind]
output_str = ' '+str(city_name)+' with highest population: '+str(highest_population)
return output_str
", ATTR([City]),SUM([Population]))
I have a question, can we do all kind of stuff and make dashboards inside Tablaeu from Python or just calculations.
Can we make charts and dashboard too ?
No, we can not. Tableau define several data types that can be returned from python. And you can not return picture or any matplotlib object.
