For the second graph (say a bar chart), the variable to which the range is being assigned is having not having any value.

Just for terminology: range in this context means the same as with mathematical functions; so if you have a bar chart, the range denotes the minimum and maximum height of the bars. Is this correct?

In this case, if you have no range given, I would derive the range in some reasonable way from the data itself. For the upper bound of the range, you could simply take the largest value to plot. For the lower bound of the range, I would not take the smallest value (because this would result in a bar of height zero), but something smaller. If the values are all non-negative, you could try 0 as a lower range or, if this makes the bars look "too equal-sized", you could take 80% of the lowest value for the lower bound of the range.
