First of all, what is a sparkline?
It is a small line chart, without axis or grids. It typically represents a measure variation over time, and it is often embedded in text.
Hey, wait a moment! Why we developed a custom visual that is similar to a built-in one (the Line chart)? Because sometimes, similar is not enough.
Our sparkline includes several useful options and takes great care to the use of real estate. Here are some examples:
Showing highest/lowest data points
Showing the last value (it can be the sum of the values in the series or the average value)
Showing a target value
Showing a target area
Coloring the sparkline area
Showing multiple measures
Showing multiple items in a category
Ignoring null data points
As previously said, the new API are not completed yet, so we postponed some key feature as:
- Value label formatting (display unit and decimal places)
- Tooltips displaying
Please, be patient! We will include these feature after the required APIs will be released by Microsoft.
UPDATE Dec 20, 2016: we just released a new version that include the missing features!
You can watch a demo video and download it here.
