Don't draw chart / series if set of data is empty.
Currently I have an issue where if a set is empty, the line will still be displayed, and if all of the series are empty, a chart will display without any lines. This should be handled by default where if the series is empty, do not draw the line for it, and if all of the series are empty, do not draw the chart.
I'm not sure what you mean... Can you elaborate with an example?
Here's an empty series. No line is shown: http://jsfiddle.net/vqq6rrtr/
An empty chart will render the chart title, credits and stuff that is not related to the data. If that is not desired, you should defer creation of the chart until the data is ready.
