Pie chart is one of the most common charts seen in a visualization. The first time I came across this is a long time back as a kid while using Powerpoint.
So yeah, it’s been around for a long time. Probably the same as bar charts.
When should you use this chart? Both Charts are best to use when you are trying to compare parts of a whole.
The difference between pie and donut comes in with how it is read. With pie, you compare the arc length of each slice. …
It’s the time of the year when you get to participate in the biggest event by Tableau — IronViz.
Quoting Tableau “Iron Viz — the world’s largest virtual data visualization competition — ignites and showcases the power of the Tableau Community, giving you the opportunity to interact with data rockstars worldwide. Three finalists will advance to the 2021 Iron Viz Championship this November”
I love the Tag line used by Tableau for this event: Win or learn — You can’t lose! That is so true. …
Tools like Tableau, Power BI have made visualizations easier for us. We can do anything with these tools. But even after that, Bar charts are the MOST used charts, especially on Business Dashboards.
It is best used to show the distribution of data points and to compare the values across the dimension.
Let’s take an example — If you’re looking at the sales by Ship Mode and need to understand which mode has the most sales then a bar chart is the best fit.
They are quite powerful if used in the right place, in the right manner.
We spend an awful amount of time on a dashboard that ends up being hardly used. Hurts pretty bad, right? So you sit there and wonder, what went wrong? In most cases, it all comes down to how easy is it to use the dashboard.
When we design a dashboard, we should also think like the end-user and ask ourselves some basic questions
1. Is this overwhelming to look at?
2. Can I navigate through it on my own?
3. What does this chart show?
Now let’s look at these questions in detail.
Tableau suggests limiting the number of views…
I recently witnessed some amazing work from the #datafam community on Portfolio Day. That’s when I got an idea to build this in Tableau.
I have been working on a code to get the tableau public details along with the images, but my work was halfway done when I came across Ken Flerage’s blog on Tableau public services :) Do check out his blog to know how he pulls the data.
So the next step is to get the images of the viz. This blog would cover how you can download the images for your viz and create a…
If you’ve been working with the Tableau version before 2019.2, you must have used a parameter swapping method. From 2019.2 onwards, Tableau has introduced Show/Hide containers which can also be used to swap worksheets.
But in this blog, I’ll be talking about swapping worksheets using parameters only and a challenge that I had faced initially.
Taking an example, you have two worksheets with bar charts: Bar -1 and Bar -2
Place them in a vertical/horizontal container.
Quick Tip: It’s good to name your containers. It comes in handy when you’re navigating through a bunch of container hierarchies to locate something.
After a hectic week, I happily opened my laptop on a late Friday night. I was eagerly waiting for the weekend to work on the viz idea I had. I downloaded the images for my viz and when I assigned them in Tableau, I notice that it is all messed up!
So what went wrong? I’ll cover a few scenarios and ways to assign shapes correctly
Let’s start with the basics. To assign the image as a shape it must be in the Shape folder.
The folder can be found here
My Documents > My Tableau Repository > Shapes
You must have probably seen this on websites. A bunch of images present and when you click on one, it expands or zooms in.
When I was working on my “Forbes 100 Women of the year 2020” viz, I wanted to add in this feature to expand the image of the selected woman.
I’ll be walking through the steps to build the view. So let’s jump it!
For sake of simplicity, I’ll be using the superstore dataset.
The first thing would be to create the grid-like structure (small multiple) that I have above.
Ryan Sleeper’s blog on “How to Make Trellis…
Initially, I had created this in yellow but I had my eye on a few other colors. That’s when I got an idea to add an option to swap in Tableau.
This is the final view that we are aiming to build.
Let us jump in! :)
We first need the images that we’ll be using in our dashboard.
I created them in AdobeXD but feel free to use any other tool of your choice.
I created 4 different background templates of each of the colors.
Have you been in a situation where you had to download a bunch of images manually? Welcome to the club! Been there, done that.
But you don’t have to do that anymore.
Automate your boring stuff with Python (Stole it from the book :D ).
For this tutorial, I have taken an example of extracting the movie posters from IMDB.
Now the above link has 100 images and it is not ideal for you to download them individually. And secondly, the images on this page are way too small.
So the idea is to use the Image of the…
