I have an issue with the Linechart. Dashed/Dotted lines in the beginning.

Hello ladies and gentleman,
I'm having a problem with the Linechart, at first it was the background color, 'backgroundColor' doesn't apply the designated color, I used backgroundGradient.
I'm still getting red/green lines in the beginning of the Chart, how do I remove them?
