How to display reload text in iOS-Charts?

I am using the Charts cocoa pod to display a line chart. When the user changed an option I need to update the chart. Depending on the selection, this can take 1-2 seconds. Therefore, I want to display a text that the chart is updating. Is there any option available to do this using the charts package?

Thanks, Jack

Solution

reloading text or so called toast, progress, you can find many open source projects for it.

I used to use toast, but also there is a famous one https://github.com/jdg/MBProgressHUD

This is NOT about Charts library itself, so don't tag ios-charts.
