Can I implement the following with Charts??

---

I am trying to plot some data on a simple line graph. Below is my class for storing the data.

How do I plot my yValues with time or date which are strings?

Also, I would like to add title as a UIButton to each data point in the graph. Tapping on the UIButton should display the corresponding detailedNote is a small popup. I have searched and digged into a lot of Chart libraries for iOS but didn't find a way to add this simple functionality.

Also, what is the way to filter and plot data for "Today", "Last Week", "Last Month" or for any interval of time?

Can I do all of this with iOS libraries like Core Plot and UIBeizerPath without help from any 3rd party frameworks/libraries? I prefer to use UIBeizerPath as I can smoothen the graph.. https://medium.com/@ramshandilya/draw-smooth-curves-through-a-set-of-points-in-ios-34f6d73c8f9#.28frf03to

Can someone point me to the right resources.. Posting swift code is highly appreciated!

class NoteEntry {
var title: String?

var detailedNote: String?

var yValue: Float? = 0

let timeString : String  = {
let formatter = NSDateFormatter()
formatter.dateFormat = "h:mm a"
formatter.AMSymbol = "AM"
formatter.PMSymbol = "PM"
return formatter.stringFromDate(NSDate())
}()

let dateString: String = {
let formatter = NSDateFormatter()
formatter.dateFormat = "d"
return formatter.stringFromDate(NSDate())
}()

let dayOfTheWeekString: String = {
let formatter = NSDateFormatter()
formatter.dateFormat = "EEE"
return formatter.stringFromDate(NSDate())
}()

let monthAndYearString: String = {
let formatter = NSDateFormatter()
formatter.dateFormat = ""
return formatter.stringFromDate(NSDate())
}()

}

I guess the first thing you should do is to play with ChartsDemo. You will find all answers there. Adding buttons are useless with this library.

And I believe all your needs will be satisfied with this library - or definitely you can write them without any 3rd parties
