Chapter 8: Components That Show Trending
In This Chapter
• Understanding basic dashboard trending concepts
• Comparing trends across multiple series
• Emphasizing distinct periods of time in your trends
• Working past other anomalies in trending data
One of the most common concepts used in dashboards and reports is the concept of trending. A trend is a measure of variance over some defined interval — typically time periods, like days, months, or years.
The reason trending is so popular is that it provides a rational expectation of what might happen in the future. If we know this book has sold 5,000 copies a month over the last 12 months, we have reason to believe that sales next month will be around 5,000 copies. In short, trending tells you where you’ve been and where you might be going.
In this chapter, you explore basic trending concepts and some of the advanced dashboard techniques you can use to take your trending components beyond simple line charts.
