click 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.
One aspect of data visualization we all have been discovering over the years is that when we talk about data visualization we often think that the choice of which graphical representation to use is the most important one to make. However, deciding what to visualize is often equally, if not more, important, than deciding how to visualize it. The goal of this visualization was to engage readers in finding and telling their own stories in the data. Special thanks to Neil Richards for this wonderful creation.
A Pareto diagram is a simple bar chart that ranks related measures in decreasing order of occurrence. The principle was developed by Vilfredo Pareto, an Italian economist and sociologist who conducted a study in Europe in the early 1900s on wealth and poverty. He found that wealth was concentrated in the hands of the few and poverty in the hands of the many. The principle is based on the unequal distribution of things in the universe. It is the law of the “significant few versus the trivial many.” The significant few things will generally make up 80% of the whole, while the trivial many will make up about 20%.
This week we will be looking at Sub-Category Sales by Month, and creating a highlight table of which sub-categories were the Max and Min Sales in that Month.Each Month will Highlight the MIN Sales in Red, Max Sales in Blue.Allow users to Filter by Year and/or Category.Pay attention to formatting and how the Table adjusts in size according to how many Sub-Categories are being shown.
This week we will need to use some formatting skills and the knowledge of formatting color. You’ll also be using the rarely-utilized hierarchy on this dashboard and you’ll need to utilize the “+” and “-” to drill in and out of the hierarchy.As you complete this example, feel free to share on Twitter using the #WorkoutWednesday hashtag. Don’t forget to tag @VizWizBI, @RodyZakovich, and @LukeStanke. We really want to see your work.
