Fill statistical values with infinity if no values could be calculated

If percentiles could not be calculated (e.g. not enough data points or infinity in any of the input values), fill with infinity to indicate missing data.

The previous solution caused no statistical curves to be displayed due to wrong number of elements in the percentile vector.
