NSString methods for y values/popups?

[kajensen]

I think it would be a good idea to have delegate methods to define a custom NSString for y-values/popups.

good idea,strong demand.

if somebody wants my solution, its at https://github.com/kajensen/BEMSimpleLineGraph (d8f2414) ... there is now an optional delegate for y labels for value (not index!). This applies to popup labels as well, but keep in mind that there is a limited amount of space for these labels. The label shrinks to 50% size but anything with a decent amount of characters will be hard to read. Feel free to improve my solution, but this is working for me. (side note: not really sure what the popuplabel suffix method is used for, but this overrides it, check the change logs).

@kajensen You should make a pull request so your changes can be discussed and then merged into the main project.

The popupLabelSuffix adds a suffix to a number on the pop up labels. For example, if your graph was charting miles over time, you might return a mi suffix. So instead of simply showing 9.0, the label would display 9.0 mi.

How can I implement string values to popUp labels from array? I have saved 3 string values in an array (min, zero, max) assigned to objectAtIndex in arrayOfValues and would like to display them in pop up labels accordingly. How do I pass the data to the method below and change the "dataPoints" array please?

if ([self.delegate respondsToSelector:@selector(popUpSuffixForlineGraph:)])
    self.popUpLabel.text = [NSString stringWithFormat:@"%li%@", (long)[dataPoints[(NSInteger) closestDot.tag - DotFirstTag100] integerValue], [self.delegate popUpSuffixForlineGraph:self]];

else
    self.popUpLabel.text = [NSString stringWithFormat:@"%li", (long)[dataPoints[(NSInteger) closestDot.tag - DotFirstTag100] integerValue]];

Thank you for suggestions
A.

@alessign Please see the README and the Wiki for instructions on using BEMSimpleLineGraph and getting your data source setup. In the future, you may also want to ask your question by opening a new issue.

I am going to close this issue for now, seeing as popup suffixes are fully supported and popup prefixes are well on the way. If you're looking for something different, please let us know and we can reopen the issue.
