Maintain Rank and % of Total Sales After Filtering (Tableau)

 




Business Request:  In the bar chart, keep the rank and the % of total sales the same after filtering for specific region.


Solution:  


1)  To keep rank the same after filtering for Region, use the tip from this video:


a)  Create a formula ‘Region Filter’ with WINDOW_MIN function.


@Region Filter

WINDOW_MIN(ATTR(Region))


b)  Pull @Region Filter to the Filters pane and click ‘OK’ button.


c)  Click on down arrow in the ‘Region Filter’ and select Compute Using ‘Cell’.


d)  Select ‘Use all’ and then click ‘OK’ button.


e)  Use ‘Region Filter’ as filter.



2)  To keep the % of sales the same after filtering for Region, use the tip from this article:


a)  Create a formula ‘% of Total Sales’ using FIXED LOD.  The reason is FIXED LOD precedes dimension filter in Tableau order of operation.  This will ensure that when the Region filter is applied, the % of total sales is maintained because FIXED LOD precedes dimension filter.



@% of Total Sales

SUM(Sales) / AVG( { SUM(Sales) } )


b)  Use formula @% of Total Sales to create the bar chart.



Good luck everyone!

Model Context Protocol: Unifying AI Data Access (Podcast)

 

Model Context Protocol (Podcast)

   


The Model Context Protocol (MCP) is an open-source standard created by Anthropic to facilitate better connectivity between AI assistants and various data systems.  Historically, AI models have struggled with data isolation, requiring custom integrations for each new data source.  MCP aims to solve this issue by providing a universal protocol for secure, two-way data connections, enabling AI systems to access information from content repositories, business tools, and development environments more easily.  This allows AI models to produce more relevant responses by understanding the context around a task.  Developers can expose data through MCP servers or build AI applications that connect to these servers.

Custom Data Labeling for Line Chart (Tableau)





Business Request:  Customize data labeling where users can dynamically select what years to display value at line end and what years to display value for every month on line charts.


Solution:  We will use set selection and dual axis to customize the data labeling.


1)     Create a set for Year of Ship Date that will display values by line end in line chart (@Ship Date To Show Line End Set).


2)    Create another set for Year of Ship Date that will display values for every month in line chart (@Ship Date To Show All Values Set).


3)    Create formulas to calculate for sales based on each set.


@ Sales (Line End)

If [Ship Date To Show Line End Set] then [Sales] end


@ Sales (All Values)

If [Ship Date To Show All Values Set] then [Sales] end


4)    Use these 2 formulas to create a dual-axis line chart.


5)    Show sets for users to select years to display value at line end and to select years to display value for every month on line charts.



Many thanks to Jim Dehner for help with the solution.

Hide Null Value in Filter But Keep in Calculation (Tableau)

 




Business Request:  Hide Null value in filter 'Downtime Type' but still keep it in calculation and show only 'Planned' and 'Unplanned'.  The reason is having Null value in the filter might be confusing for the users.


Solution:


    1)  Create a fake field to assign Null a value that exists in the data set for field 'Downtime Type'.


        @Fake Field

        CASE [Downtime Type]

        When null then 'Planned'

        Else [Downtime Type]

        END


    2)  From this 'Fake Field', create a set 'Fake Field Set'


    3)  Create a 'Fake Field Set Filter' to be used as a filter


        @Fake Field Set Filter

        CASE [Downtime Type]

        When null then True

        Else [Downtime Type] in [Fake Field Set]


    4)  Drag @Fake Field Set Filter to filter shelf and select 'True'.  Use 'Fake Field Set' as a filter which should have only 2 values 'Planned' and 'Unplanned'.



Many thanks to Diego Martinez for help with the solution.

Qubits, Physical & Logical (Podcast)

 

   
Qubits, Physical & Logical (Podcast)

   



In quantum computing, a qubit is the fundamental unit of information, analogous to a bit (binary digit) in classical computing, but capable of representing 0, 1, or a superposition of both.


A physical qubit is a real, physical system (like a trapped ion or a superconducting circuit) that can exist in a superposition of states.


A logical qubit is a collection of multiple physical qubits to achieve greater stability and error correction.  It's not a physical entity, but a redundant encoding of qubit's quantum state using multiple physical qubits.


Listen to the podcast for detail explanation.

NVIDIA GTC 2025 (Podcast)

   





NVIDIA GTC 2025 in San Jose has concluded with a big fanfare and what an amazing conference it was.  This developers’ conference was the destination for all things AI and more, an incredible place to explore and exchange grand ideas from agentic AI to humanoid robots to quantum computing.



Quantum Computing




NVIDIA CEO Jensen Huang with CEOs of quantum computing companies D-Wave, IonQ, Pasqal, Rigetti, QuEra, Quantinuum, SEEQC, Atom Computing, Infleqtion, PsiQuantum, Alice & Bob, Quantum Circuits



GTC 2025 debuted Quantum Day, showcasing the rapidly progressing field of quantum computing where the impact will be far-reaching.  This next-generation field will push the technological boundary with extremely fast computing that's beyond today's fastest supercomputers.  Foreseeable future will have QPUs, GPUs, and CPUs working together to extend classical computing.  


The challenges of quantum computing are scalability, fidelity, error correction, coherent time, and latency.  New methods and algorithms will have to be created in order to apply quantum computing to real-world problems (trillion-dollars business idea here).



Strategic Partnership  






ServiceNow expanded NVIDIA partnership to collaborate on Agentic AI capabilities that allow corporate customers to assess AI Agent performance on the powerful ServiceNow Platform.
