I have a chart that represents Numeric Values (Y) over Time (X).

One line represents TODAY'S values and the second line represents Last Year's values.

Since I have complete data for Last Year it should span the entire chart. However, I only want the Today's line to draw to the current hour. Right now, it draws across the whole chart.

Well, it took me a bit, but I finally discovered how to resolve my problem.

RGraph.array_pad(array, length[, value])

var curValues = RGraph.array_pad(currentYValues, LastYearsYValues.length);

This effectively made both arrays the same size and placed nulls into currentYValues.

Now the chart appears as I want it to. On to adding some tooltips! Having fun with RGraph!
