Hi r/Tableau!

Like many of you, I’ve often felt the pain of trying to build flexible, hierarchical matrix tables with native subtotal drill-downs in Tableau—without having to pay hundreds of dollars for third-party dashboard extensions like SuperTables.

With Tableau’s introduction of Viz Extensions (2024.2+), I decided to tackle this natively. I built a 100% free and open-source Viz Extension that brings Power BI’s matrix functionality directly to your Marks Card.

Key Features:

• Hierarchical Drill-Downs: Expand and collapse rows/columns using intuitive + / - controls directly on the sheet.
• Dynamic Subtotals & Grand Totals: Recalculates automatically as you navigate levels.
• Native Integration: Works as a custom Mark Type—just drag and drop your dimensions onto the shelf.
• Zero Cost & Open Source: Hosted via GitHub Pages, meaning zero infrastructure costs and complete data privacy (runs entirely client-side in your browser).

🔗 Links & Resources

• GitHub Repository (Code & .trex manifest): https://github.com/Arley-Economist-Dev/Matrix-Pro-Tableau

🛠️ How to use it:

1. Download the .trex file from the release section on GitHub.
2. In Tableau (2024.2+), go to your Marks Card -> Viz Extensions -> Add Local Extension.
3. Select the .trex file, drag your dimensions, and you're good to go!

This is a passion project built for the #DataFam to solve a common headache. I’d love to get your feedback, feature requests, or bug reports to keep improving it!

Let me know what you think!

I am trying to create map representing different outgoing destination sites for my company. Currently I’m just trying to highlight each state. However, some states are not jiving by with Tableau. I don’t know what else to do because my excel sheet is all in the same format and I cannot make my geolocation the United States because I will be incorporating different countries. Someone please help me I’m loosing my mind.

I was working on a self project and generated the sheets easily and changed to a different data source later in the another tab and so on and eventually i returned to this tab and it shows error the data it should be linked to is sheet 1 (country) but its showing as if its linked to expenses. i can manually redo it but want to know if there is any way to rectify this easily.

This might be too niche for the group so bear with me! My coworker and I just became our cloud admins since our boss resigned. We're now in a position of negotiating the contract with Salesforce. Apparently, we have been paying for Signature Success support for the last few years and it costs like $80k per year (almost as much as the total for just the licenses). It's the highest tier of support. As far as we know, our boss never used it or passed on the benefit to any of us Tableau creators. Now the SF people are basically begging us to keep it in the contract for the upcoming year. I just don't think we need it - anyone have experience?

I am working on retail data, it's stored either in fiscal week range (last 4) or a transaction date field and the business fiscal week, month are derived from this.

This makes up for 1 transaction date x sku grain for the main table.

I need a filter/parameter like a date picker/scrollable or multi select or a calendar that helps us pick a business fiscal week range or a specific month or q particular week in a particular fiscal month and every sheet, kpi, visual rearranged according to that picked range.

How do I build this? Is there a calendar widget I can use or do these need to be multi select

I want to learn Tableau from scratch bit idk from where pls give me recommendations

Hi everyone,

I'm looking for any news about the release date of the next 2026.2.x minor update for the on-premises Server and Desktop versions. Has anyone heard anything?

Best regards,

Hi everyone,

I run several Tableau Server instances. Each instance runs on its own VM in its own network. The Prometheus Node Exporter is installed on these VMs and pushes data to the Node Exporter dashboard in Grafana. I’ve disabled a few collectors to avoid having too many metrics. Do you have any other best practices? I don’t have any Tableau-specific metrics; I’m just keeping an eye on the machine. How do you handle this for separate instances?

Thanks!

My dashboards look correct when I'm on desktop editor but as soon as I go to web editor or the published version, they get "cut" on the right. I've already tried sizing down the dashboards and changing the layout to standard desktop but I still get a cut view with no scroll bars. Last image is what I see before publishing, second is what I see on web.

I'm a Salesforce specialist working with Tableau Next so I've been playing around for a while with both Next and Tableau Cloud (Next, Cloud and Desktop are all included in the same package), trying to evaluate the pros and cons.

Among many things the one which I find most limiting to start with is the fact that when you define the Semantic Model (basically where you build the relationships between tables, like the Data Source layer in Tableau Cloud) in Next you can NOT reuse the same table more than once. If say the ServiceAppointment table has 2 fields pointing to the UserId, but with different meanings, you can't add the User table twice.

The only thing you can currently do is build multiple "Logical views", each of them containing the User table, and then 1 relationship for each Logical view: the limitation with this however is that at the moment you can't use fields from tables inside a Logical view (for example the UserRoleId) in your viz's calculated fields.

The non-reusability of tables seems like a big gap compared to Tableau Cloud but I'm also not 100% sure that's the way you'd normally wanna build the Data Source in Tableau (I found no other approach though) so what is your opinion? Am I missing anything? Is there any different approach?

It tells me:

The online map could not be loaded.

A temporary service disruption caused an error when fetching parameters from Tableau. Try again later.

I didn't even know Tableau maps could be down. I thought the basic map was included in the massive download. Is the problem me somehow or is it really down?

I am just starting data analytics, I started from tableau and i can make pretty dashboards but data storytelling is soo hard . Can anyone tell me how they make data insights valuable? Also how do you read the charts properly? Please help me

I am currently developing executive-level board dashboards using both CRM Analytics (CRMA) and Tableau, but have hit critical licensing and technical bottlenecks in both platforms:

CRM Analytics: The solution is built, but Salesforce's lack of a low-cost "Viewer" license makes scaling to multiple board members financially prohibitive due to hefty per-user licensing fees.

Tableau: The native Salesforce connector relies on Bulk API v1, causing it to time out and fail when processing our massive data volumes.

To bypass these vendor constraints, I successfully built lightweight visualisations for simpler datasets using Chart.js and D3.js. However, I need to render a complex chart that processes 46 million records, which crashes standard client-side libraries like Chart.js.

I am seeking architectural advice, workarounds, or custom engineering solutions to bypass these limitations and efficiently aggregate and render this high-volume data.

Aside from Golden Analytics, any recommendations for the best embedded analytics solution?

We're 100% leaving Tableau. The only question is a big one: what's next.

Why? SF hubris from Benioff and his acolytes have meant the death of Tableau since true innovation nearly completely stopped in late 2018. Had they simply listened to thundering feedback from customers and original Tableau employees...well, whatever, that's part of hubris.

Anyway, we're breaking up with you, SF, but hoping for insights on where to go next. Love the idea of using the datafam for this purpose.

Hello!

I'm a comms professional with 12+ years experience working for charities, foundations and non for profits.

I earn a good wage relative to my peers but have - for complicated, frustrating reasons - hit a bit of a glass ceiling.

My partner and I are expecting a baby in 5 months and I would like to earn just a little extra money. I've also used Tableau but from a funder's side. E.g., one of my first ever projects was to fund and oversee a data analyst to build Tableau dashboards. But I can't build them myself.

Questions...

- If I were to learn how to build dashboards, realistically could I add to my salary? It's unclear to me what the pathway would be. "Comms expert and Tableau builder"? What's the practical route to more money?

- How difficult is it to become a skilled operator of Tableau and how long does it take? Am wary I'm potentially learning a difficult new skill just before I become a dad and while I already have a busy job.

Thank you!

Hi everyone,

Thanks!

Hey guys, I’ve an urgent requirement to extract user info from Tableau server (prod/non-prod) in excel file and save that file on a specified location. Since its taking lot of manual effort, is anyone aware of any automation scope on this?

I do have the python script with me that is being used to extract all the information from Tableau server however that is being run manually, and I want to automate the entire process of extracting just the user info and saving that file to a specified location.
Feel free to advise if anyone has done this or something similar in past.

Hi! I've been doing more things with alerting, and now want to give users the option to set up their own alerts. The documentation I found wasn't very clear. Do I need to enable the Web Edit permission on the workbook? If so, what other access am I giving the user(s)?

Thanks!

Among my frustrations,

the first one is that designing and adjusting prototypes using Figma or PowerPoint before finally getting a finished product can be really annoying, especially when the client keeps asking me to redesign things over and over again - there's always a gap between the prototype and the final product.

The second issue is that when I start a new project and want to reuse something from before, like visualizations, layouts, Tableau doesn't really have a good modularization or templating system.

I took a massive dataset with over 1.6 million job descriptions and built a whole pipeline around it for my internship! I handled all the initial data cleaning and preprocessing in Python using Pandas (standardizing column names, dropping duplicates, and cleaning up missing company profiles).

After getting the data cleaned up, I threw it into Tableau to build out a dynamic dashboard. I made a qualification drilldown map using latitude and longitude coordinates to show hiring density globally, plus a bunch of other sheets tracking salary distributions, company sizes, and work types.

The coolest part was embedding the live Tableau Public sheets straight into a custom HTML frontend I put together in VS Code so it functions as a live web portal!
