Calendar Scale and background Grid don't match

Scheduler Javascript
#1

I changed the calendar hour vertical size by scheduler.config.hour_size_px=70

Works fine however by background grid ( alternating grey and white bar ) every 3o minutes does not line up with hour spaces.

What setting do I need to change to match the background to the hour size?

Hi
you need to create backgroung image of the proper size and use it instead of default one.
The default image for terrace skin can be found at codebase/imgs_dhx_terrace/databg.png
css class is following:.dhx_scale_holder { background-image: url(new_image.png); }
