How do I create a Google Line Chart that displays two or more lines, with a different number of data points in each series?
For instance, I want to create a chart with 2 lines, one showing the expected values over time and another showing the actual values over time. The date range and expected values are known in advance so I can fully graph them, but the actual values may not be fully known yet (e.g. the date range covers some dates in the future).
