Creating Dynamic and Synchronized Axes


Tableau allows developers to have creativity and flexibility in their design of dashboards and visualizations but while the beautiful charts and graphs may grab our attention, the reason why we are creating these visualizations is to gain insights about our data. Data is one of the most, if not the most, valuable asset on earth. So how we present that data is of the utmost importance. “With great power [that data gives you] comes great responsibility [to represent that data accurately]”. The accurate representation of data is critical; if you rely on data to guide business decisions and that data is misrepresentative of reality in any way, it can have a negative effect.

Many times, we find ourselves comparing data values or trying to understand how data interrelates. In Tableau, we tend to use our visualizations to do so because leveraging our pre-attentive attributes is key to gaining quicker insight. Thus, we need to be aware of how we are representing data and we need to compare values in the same “light”.

In this blog, we will be going over two use-cases in which the use of an invisible reference line can help accurately depict relative sizing of data. Reference lines are typically implemented in charts to add context, however that does not mean that they must be visible!
