Onion diagram is a type of circular diagram that is made up of concentric circles, which looks like the cross section of onion. The innermost circle is the core, and the outer layers are dependent on the core. Each layer is dependent upon the layer inside of it. Onion diagram can be adapted when you need to show layers of a system. This chart is used due to the fact that it has a clear visual representation that is easy to read, and it has a strong visual impact.There are tons of example out there and few of them are listed below.Refer the Wikipedia Link . This post sets out how to build a Onion chart without any data prep before Tableau
The new set action feature in Tableau 2018.3 means that a selection of data points in a visualization can be stored in a set. Set actions are much more than a new type of action; they extend Tableau’s interactivity to support custom user-defined behaviour. A set can apply different behaviours to various target sheets.Set actions take an existing set and update the values contained in that set based on a user’s action in the viz. You can define the set action to include: the source sheet or sheets it applies to. the user behavior that runs the action (hover, select, or menu).
Let’s break the dashboard design and think how we should use layout containers. A “Layout container” is a type of object. It helps to organize worksheets and other objects on the dashboard. Layout containers usually create an area in the dashboard sheet where views or objects automatically adjust their size and position based on other views or objects in the dashboard. In simple words, it allows you to group objects horizontally or vertically within the dashboard workspace.
Edward Tufte, a pioneer in the field of data visualization and data design, maintains that pie charts “should never be used,” and Stephen Few calls it “by far the least effective” graph intended to facilitate quantitative communication and no one denies this theory but yet, we support pie charts. Why?
Pie charts are useful for representing a simple proportion of a whole, and can easily be interpreted by expert and novice alike. Even Viz Guru Mr.Few admits that there’s one thing the pie chart does better than any other visualization, and that is convey the part-to-whole relationship.
Waterfall charts are ideal for showing how you have arrived at a net value, by breaking down the cumulative effect of positive and negative contributions.The initial value and the resulting total value are represented by bars in the visualization, and the value changes in-between are shown as floating blocks that indicate the ups and downs. As a means to follow the development of the value from start to end, transition lines can be added between the blocks. This is very helpful for many different scenarios, from visualizing financial statements to navigating data about population, births and deaths.
Crosstab or Cross Tabulation is used to aggregate and jointly display the distribution of two or more variables by tabulating their results one against the other in 2-dimensional grids. Cross-tabulation is usually performed on categorical data — data that can be divided into mutually exclusive groups. Cross-tabulations are used to examine relationships within data that may not be readily apparent and if you can highlight a specific column or row in your crosstab it will help you to understand the quantitative relationship between multiple variables.
This week Rody back with a fairly simple challenge, but one that has a few useful tricks that could help spice up your next viz. The tricks used in this challenge are geared toward design, but have additional benefits. This Workoutwednesday Challenge can teach you some advance usage of Tableau function like use of Regex function, MID function and how you can utilize ASCII characters on your calculation.
