Tableau is a great tool and you will know the more you use it. At first, it can be difficult, but practice makes it perfect. I have come across a lot of common errors during my experience using Tableau. I will describe some common errors that tend to occur in dashboards in this article.
- Colour Selection
Most times people in their dashboards would want to use very vivid or a mix of colors. This is going to draw attention away from your material and only to the colors. Your users can also be confused by many colors. You should choose a color scheme when building a dashboard and stick to it. Your color scheme should usually be calm and suit your dashboard’s look. I like to use the Color-Blind color theme because it’s very simple and it also appeals to blind people. If you want to create your own color palette, click here to learn how.
- Dashboard Confusion
It’s veryimportant to have a lot of information on a dashboard, but if you try to puttoo much information on it, your client will be confused. A good thumb rule isthat if you add so many graphics to your dashboard that they can’t all fit on ascreen and are easy to read, there’s too much detail. Once you build yourdashboard, talking to your company is a great idea so you know exactly what toplace on the dashboard. If the client asks for too much information to beplaced on a dashboard, you should turn your dashboard into a story. This meansyou’ll create multiple dashboards and link them all through the purpose of thestory.
- Proper data cleaning
The mostcritical part of working with data is to clean up your data. You typicallyspend 75% of your time cleaning up your data and then 25% of your time actuallybuilding things with your data. There are a lot of tools for cleaning data. Ifyour data is not cleaned properly, the dashboard will be unreliable andincredibly difficult to work with. If you used data that is not properlycleaned and you have to go back and redo your dashboard, something that can setyou back. This can be very frustrating, so when cleaning up your data it isimportant to take your time.
- Sticking on to Basics
If you’renew to using Tableau, sticking to the basics is great, but if you’re neverplaying with the method, you’re never going to improve. There are several typesof options for visuals in Tableau, as they all serve different purposes. Youcan also edit them in certain types of visuals. Symbols, orientation, etc. canbe changed. If you want to keep moving forward with a Tableau career, you needto make sure that you create the best possible visuals. This will come withpractice, but you definitely need to use a variety of visuals and edit them tofit the client’s needs in order to achieve this. It’s also very important topersonalize your dashboard. It’s agreat way to create a header. You’re going to want to leave your own logo onall your dashboards to remind people who you are.
- Always listen to your customer
You wantto make sure you listen to your client while building a dashboard. You arebuilding a dashboard for them to use, so make sure it includes the relevantinformation. When you find something interesting that your customer wants, thenyou should contact them and check with them before adding it to theirdashboard. For example, I’d set up a call with the client as I built dashboardsat my internship before I started the dashboard. I would specifically ask themhere what questions they had about their results. Then I’d create a graphic foranswering all their questions and adding them to the dashboard. This is thebest way to ensure that only information relevant to the client is included.
- Don be Afraid on Trying new things
Tableau’sbest way to learn is to try new things. Tableau’s fundamentals can be picked upvery easily, but you need to perform an experiment to be able to do so. Lookingat other people’s dashboards and talking to other users of Tableau is a greatway of doing this. If you want to play around with data that does not belong toyour client, there are plenty of sample data sets on the Internet.
Ifdesigning dashboards, the above are some items to avoid. To stop these issues,you will be able to create graphics that are clean and easy to read.
