9/12/2023 0 Comments Tableau prep builder 2021.1![]() It’s a great new feature that allows you to set your filters, so the next time you come to a view, it has saved your changes whilst allowing other users to do the same. On the Tableau Server side, we have the nice new feature of custom views. Tableau 2020.4 – Tableau Server Custom Views Now, you can go into Tableau and extend your model for however long you want from the pre-set list or custom: This is all now possible by way of axis extensions. Whenever you are modeling, one of the things we want to do is move into the future and run some predictive analysis with our model in forecasts. These are ways of doing predictive modeling, linear regression and progression. ![]() There are now two additional models located in the table calculations functions: MODEL_PERCENTILE and MODEL_QUANTILE. Tableau 2020.4 – Predictions and Date Axis Extend Now with block commenting, you can use the markers /* and */ that make it simpler to debug. The errors occurred when you had a complex calculation, and when trying to figure out which piece of the calculation was your problem, it starts to get overly complex. If you wanted to comment a specific line out for Tableau to ignore, you could do two // on the line, and it would be ignored by Tableau when the calculation ran. Tableau 2020.4 – Block Comments in Calculations You can go ahead and do all of your data work in the Prep browser with no loss of functionality and save it back to the server. Now, you can access Prep from the browser within your Tableau “Connect to your Data” page. ![]() If you have never used it before, Tableau Prep is the tool you would use to shape your data before it enters the visualisation stage in Tableau. Try not to overload your maps with multiple map layers. A word of caution, though: you can have too much of a good thing. Map layers are now super intuitive and take mapping to a whole new level. Here, we see one mark for the colour, one mark for the medical support centres and finally, a mark for the at-risk communities. Anything that has the spatial geocode globes in your field panes you can now drag to the board, creating charts like the above easily. So how did they build this? How did they get the colour? How did they get two marks into the dashboard? Thanks to map layers, this is now a simple trick. We also saw additional spatial support become available in Prep. With the map layer enhancement, we saw enhanced geospatial analysis, additional map for greater context in your map visualisations, offline map support and no more dial. This was one of the most anticipated updates that caused a lot of excitement for Tableau users. We won’t cover all of them, but below are some of our favourite features from this version. Here’s a quick summary of the highlights from this version: With the vast increase in the size and complexity of data, we see Tableau rising to the challenge and transforming that data into useful insights. To frame the discussion, here’s a quote we found from Aaron Koblin: “I think you can have a ridiculously enormous and complex dataset, but if you have the right tools and methodology, then it’s not a problem.” This is a focus that a lot of us have in the analytics space when working with data. This blog is a thorough recap of that webinar, but if you’re looking to just catch the replay, skip down to the bottom of the post! In this recent webinar, we talk Tableau releases, past, present and future.
