Using both String and Date on axis charts ios

I am using Charts library by Daniel Gindi

On the X axis of the line chart, I want to show 3 values (string, date, date). 1) Is it possible to format only one particular label into a string type value? 2) Is it possible at all to show different value types on one axis?

I've tried using a function getFormattedLabel(index: Int) but I haven't seen any examples of this function being used. Also, I can't find anything in documentation (it's for Android since there is no documentation for iOS): https://weeklycoding.com/mpandroidchart-documentation/

I want the axis to look like this: Click here for the example of X axis

Thanks!
