iOS Question xChart - display background image instead of an empty graphic

[ThePuiu]

I would like that instead of a blank page, the user will see a background image until he determines what sizes he wants to be displayed and the graph is generated. I tried to overlay on xChart an ImageView that would contain the image and make it invisible and send it back after the graph was generated but it does not work (it is never displayed although at creation I make it visible and send it in front)

You could use a Panel with the background image and then add the xChart with a transparent background color onto this Panel.
