Flexi Bars Swing V2 modification help wanted

I would like some help with modifying this indicator
The indicator is now showing arrows on the chart but what i would like it to do is not showing arrows but showing a histogram beneath the chart (for example just like the indicator Cycle Identifier),and maybe someone could throw in an alarm also ??

i have attached the indicator below

help is appreciated very much thank you

I also need someone to help in adding alerts (sound/email/pop up) on the above same indicator Flexi_bars-Swing_v2. Thank in advance.
