Prefixes missing when alwaysDisplayPopUpLabels = YES

I see you pushed up a commit to include prefix's. I can't seem to get them to work. Are they still being developed? I am running off the head as of this morning.

- (NSString *)popUpPrefixForlineGraph:(BEMSimpleLineGraphView *)graph
{
   return @"$";
}

This should be working in the latest commit (20d9253). I will push up a commit with example usage added to the sample project.

Are you sure you've got the BEMSimpleLineGraphDelegate hooked up correctly? It looks like it's working on my end....

Ah I found the issue. In your example you don't have "alwaysDisplayPopUpLabels" enabled. With that set to YES, the prefix's don't show.

self.myGraph.enablePopUpReport = YES;
self.myGraph.alwaysDisplayPopUpLabels = YES;

Looks good! Thank you!
