iOS / PNChart

Added a method to allow the update of both the current and the total for...

…e chart so it's display remains overall accurate.

- (void)updateChartByCurrent:(NSNumber *)current byTotal:(NSNumber *)total;

We have a scenario where our app is pulling updates to both the "checked in" (our current) and "registered and ready to check in" (our total). Since both values can be updated, the chart would not be correct if only the option for the total to be updated was not available.

Use duration property in counting label

Fix little issue in PNLineChart.m

the delegate(userClickedOnLinePoint: lineIndex:) in method(touchPoint:
withEvent:) is never called,because the point p1 is not in each line
path.So,when touch the line path,nothing happens(the delegate is
invalid).

Update method name

Make delegate methods optional

They should be optional methods so we can get rid of warning when only using one kind of these chart.
