The helm env command returns a list of the Helm environment variables and their values. It would be useful if you could pass in a specific environment variable and get its value.

.rickshaw_graph .detail .item.active from detail.css would benefit by adding 'width: auto; height:auto;' to auto-size the detail tooltip on graph mouse hover. In it's current form, the tooltip doesn't get auto-sized when using a relative/percentage based layout.

Currently we have restriction for chart's size but it works for size passed in the constructor only.

We need to either remove it or make it smaller (let's say 20x20 or something) and apply that restriction everywhere (in resize method).

For the reference see ht

It would be nice to have a flag that allows to keep only the last x versions of a chart.

Improvement description

Extend the LegendExamples with one that first shows but then hides the legend.
Why? It took me a while to find the IsLegendVisible property.
