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]))
Hello sir, if we have percentage more than 100% then how we will be present in gauge chart??
Next time make sure your audio works well. Thumbs down
noted
i am finding trouble in executing python script in tableau repository, your pan code is absolutely blurr, not readable, nothing is explained about code
good sir
Good job sir. Where are you from ?
Muchas gracias, me ayudaste mucho
You are Welcome.
Been looking to make this ,thanks
Can this be done without data densification?
This video provides a better explanation on this topic than the other videos available. Thank you!
Agreed
Hi, if we want to create 3 level dendrogram, how should we prepare the data in Excel? Could you please suggest?
No explanation of any calculations because you copy other's work. Better to give credit to the person who created all charts originally. This is called cheating.
well explained
Sir pls Tableau sikha do hindi complete
simple and clear Thanks
walikum salaam
Awesome
Excellent way in you explained with example both new and old version difference. Good job
thank you
Can you share how to work modified data streaming
thnk u sir
Amazing video.. its exactly showing the same. Thankyou so much 🙏
Hello Sir, Can you help me with the use case where percentage comes more than 100 percentage..
gauge chare are considered as good visualization if the data range is till 100%. If you have higher % of data then you can show data in a Tile. anyway I will try you some sample and will share with you.
@@kamranahmed105 Thank you so much sir. I have figured this out. I have restricted the data to 100 when it is more than 100....
Can you suggest any other good visualization which can be a good replacement for gauge

Hi, thanks for the knowledge share. My doubts are... 1 What are the main differences of .TDE & .TDS at server level...are they both behave same in server when published separately (I mean even TDE also saved as TDS) or are there any major changes that we see. And if so how will I proceed with it. 2 Will I get options to choose live / extract on Server extract / if so any possible issues
muhaaa ! what a video
Beautiful thank u

bro how to change joins by relationship in tableau 2019
excellent video - very easy to understand and follow. How do you improvise to add two more colours and range in the gauge chart? For example, in the video, it shows "coloured >50%" and "coloured <50%" and the output only shows two colours. What can we do to add, say, 2 more range of colours?
will let you know in my coming voids
@@kamranahmed105 Did you make another video to show more than 2 colors?
Salam Kamran bhai, bohat he aaala. Mashallah.
Thanks bhai
What is the best answer if interviewer asked - " why tableau introduce relationships and what is the use of it".. Please explain
It's is introduced to enhance the performance. Normal join create a common data set (a single table ) in table which requires more memory utilisation and it's also impact db performance as well. Whereas Tableau relationships are only virtually joins. In relationships tables are join contains join at db level. All the join process happens at Tableau level.
@@kamranahmed105 thank you so much.
@@kamranahmed105 but we can't create relationship on published data source right?
@@vaibhavjadhav8232 published Data Sources are for end results like SelfService or can you utilized ina ny Dashboard. But to make Relationsups you have to use Tableau Desktop
When we use inner,left,right,outer,union,join,blend .how can we understand
Thank you - I followed all steps but why is it showing me full donut instead of the half?
You must be missing something
Salam, Thank You Kamran Bhai, your way of teaching so nice and easy , we are looking forward your more videos.
Thanks
Saw 4-5 videos nothing worked, then this video helped me thank you!!
Thanks.
Copied from Andy Kriebel. When you copy from someone, at least give some credit to the guy who owns the video. All your stuffs are copied from Tableau Zen Masters. Do you have ANYTHING ORIGINAL?
Thanks. Ideas could be from anyone. and we are here to share knowledge.
Thanks kamran .please share video of unstructured data is coming from source.
Sure. Inshallah
Thanks Kamran you explained it very well. I will definitely try it out for one of my project.
Thank you so much.
Very good 👍
Hi Kamran, Is it possible to create the Gauge Chart using singe measure, Because I have to convert from Power BI to Tableau please help me.

I am bit busy with some projects. May be in a comming weeks. But if you any specific requirements then share.
@@kamranahmed105 No problem till then can you guide me fro where i can read Tabpy stuff, and if you don't mind can I have your email or contact # for discussing my requirement for video.
Hi Is it possible upto 40 levels?
Yes. But it will be very complex and not recommended for big data set
In which scenario we go ??
When you have Big data set then its recommended to use Relationships. As Relationships Keeps Tables Separated at back-end.
What is the main purpose of the Relationships ??
Join is a happening at db level and relationship is a virtual join at tableau level. In relationship mod tableau Generate separate select statements for each table used in the relationship.
