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 very important to have a lot of information on a dashboard, but if you try to put too much information on it, your client will be confused. A good thumb rule is that if you add so many graphics to your dashboard that they can’t all fit on a screen and are easy to read, there’s too much detail. Once you build your dashboard, talking to your company is a great idea so you know exactly what to place on the dashboard. If the client asks for too much information to be placed on a dashboard, you should turn your dashboard into a story. This means you’ll create multiple dashboards and link them all through the purpose of the story.
- Proper data cleaning
The most critical part of working with data is to clean up your data. You typically spend 75% of your time cleaning up your data and then 25% of your time actually building things with your data. There are a lot of tools for cleaning data. If your data is not cleaned properly, the dashboard will be unreliable and incredibly difficult to work with. If you used data that is not properly cleaned and you have to go back and redo your dashboard, something that can set you back. This can be very frustrating, so when cleaning up your data it is important to take your time.
- Sticking on to Basics
If you’re new to using Tableau, sticking to the basics is great, but if you’re never playing with the method, you’re never going to improve. There are several types of options for visuals in Tableau, as they all serve different purposes. You can also edit them in certain types of visuals. Symbols, orientation, etc. can be changed. If you want to keep moving forward with a Tableau career, you need to make sure that you create the best possible visuals. This will come with practice, but you definitely need to use a variety of visuals and edit them to fit the client’s needs in order to achieve this. It’s also very important to personalize your dashboard. It’s a great way to create a header. You’re going to want to leave your own logo on all your dashboards to remind people who you are.
- Always listen to your customer
You want to make sure you listen to your client while building a dashboard. You are building a dashboard for them to use, so make sure it includes the relevant information. When you find something interesting that your customer wants, then you should contact them and check with them before adding it to their dashboard. For example, I’d set up a call with the client as I built dashboards at my internship before I started the dashboard. I would specifically ask them here what questions they had about their results. Then I’d create a graphic for answering all their questions and adding them to the dashboard. This is the best way to ensure that only information relevant to the client is included.
- Don be Afraid on Trying new things
Tableau’s best way to learn is to try new things. Tableau’s fundamentals can be picked up very easily, but you need to perform an experiment to be able to do so. Looking at other people’s dashboards and talking to other users of Tableau is a great way of doing this. If you want to play around with data that does not belong to your client, there are plenty of sample data sets on the Internet.
If designing 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. You’re going to learn more dos and don’t as you work with Tableau more and more. You can also find more Tableau advice on the Tableau website and other blogs. All in all, Tableau is an amazing tool and when used correctly and frequently it will be extremely helpful to a company. Tableau is a very powerful tool that can be very quick and easy to show a lot of insight. For More Clear Information on Effective Utilization Visit Caddgild Technologies
