In the examples of ChartJS there's an interactive legend which allows you to hide/show a result set in the graph, i.e. http://www.chartjs.org/docs/#line-chart
I've been looking through the documentation but the only references to the documentation I found are about creating an attached legend to the graph, not this kind.
Is there an option to show this kind of legend that I'm missing?
As stated in the Chart.js Github project, Release Version 2.0.0 :
Major new features
• Charts that combine visual types such as bars and lines
• Chart titles
• Built-in legends that are interactive by default
• ... and so on ...
You must be in version 1.X.X or something, so you cannot have it.
