Ravi’s interest in using and manipulating data piqued after discovering public sources of sports data. After using Excel for months, a tutorial into using Tableau in a intuitive and interactive way lead him to discover a whole new world of visualisation – The power and ease of use that Tableau provided introduced a whole world of data visualisation, full of interactive dashboards, colour pallets and bubbles.
The opportunity to join the Data School straight out of university was one that Ravi could not miss. Having studied Economics for the last four years, he is looking forward to learning from the data Jedis of Tableau and Alteryx.
When he’s not following his hometown football team Ipswich Town, Ravi is a keen enthusiast in contemporary technology as well as film & media.

First, check out my post on Tableau 8.0.0 here Following the small differences with Tableau 8, I almost expected 7.0.0 wasn't going to be so bad. And it wasn't - For me, it performed much better in terms of speed than 8.0.0 did. Visually though, there were some huge...read more
I think that one of the things that I hate about 'milestones' and such is the finality and absolute nature of them. For instance, it was just a few months ago I bid my student life goodbye - Four month holidays, late starts and all-nighters for the sake of it with...read more
Part one of this post can be found here; Last time out, we connected to data - The first step into a brave new world of visually analysing numbers through quick-fire analytics. A change of plan for part two. After discussing with fellow data schooler Hashu, I've...read more
I had never ventured onto the Tableau Community forum properly - I mean, I'd looked up some questions I wanted answers for and found some things, but a quick glance at the queries in my first few weeks scared me off; why and how am I meant to know Tableau *this well*...read more
My first experience with Tableau was using publically football data, which I had compiled into a spreadsheet for the 14-15 season, on Tableau Public. Of course, Neil Charles' post was a good base level introduction to Tableau, but it definitely still took me a while...read more
Last week, we had our fourth client project and within that, myself and Hashu found ourselves doing a dashboard makeover for the client and within this, one of our ideas for the dashboard included having a switch between two views, as shown on his blog during Tableau...read more
Our final dashboard was one where we were given just a few hours to download, play with and build. Set on Friday, we looked at the Zillow Real Estate research database and were (as ever for the entire of last week) told to go away and build something. There's a...read more
The UN data challenge's deadline is just a few weeks away now, and using the data was the first time we we had to do some level of data preparation. This was due to the dates of the dataset making it quite a fat and short dataset, and we needed to pivot the dates into...read more
There have been far too many gun deaths in the United States. Today's dashboard took a sombre turn as we looked at "Mapping the Dead: Gun Deaths Since Sandy Hook" by the Huffington Post and took the data to create something for ourselves. If you haven't seen it, I...read more
Dashboard week continues with our second visualisation, which was using a dataset from here which was scraped by Andy. Given that we had about 3-4 hours to build, we got stuck in. Looking at the data is really interesting, after looking at the number of records per...read more
This week, we will be creating a dashboard a day, and to kick off the week we have all contributed to Andy's Dear Data Two project, and sent things across to Mr Jeffrey Shaffer Using small data, we created as many views as we could. My results are below, in the...read more
When running Tableau Server, you are able to run a number of queries from Command Prompt (cmd.exe) from the Start bar, and you should right-click and run it as administrator. Depending on your system, the default line that will show up will be different; in any case,...read more
We’ve had the legend that is Jonathan MacDonald teaching us Tableau Server this week, and the fact is, it’s been super cool. I have no knowledge of anything server related, so having JMac here as well as *the Guy* for Tableau Server, David Spezia coming in to run a...read more
One of the best things about Tableau is the ability to interact with the data that you are looking at - It's almost as if you can feel, explore and (I hesitate to say) live the data that is in front of you. This that you can really quickly understand what the data in...read more
Dashboards are one of the key ideas to which Tableau is built around. The ability to create a number of charts/tables, or as Tableau call them 'views', enables a Tableau user to create something which not only allows a user to interact with and understand data, but...read more
I commute to work, and it's a 2 hour door-to-door trip, and I tend to find little side projects which I largely start and not finish to do on the train journeys. Or I listen to podcasts, or nap. This week, our task is to blog Tableau tips daily, and I was...read more
Seven weeks have well and truly flown past, and each week seems to throw up different challenges. With training moving at a solid pace, we tackled two key areas; Chris Love returned once more to teach us combining tools and flows into Macros within Alteryx, and...read more
