With Week view:
i see to set background color for calendar , use CSS
.dhx_scale_holder{position:absolute;border-right:1px dotted #586A7E;background-image:url(imgs/databg.png);}
The two part scale created by bg image, it is not possible to achieve the same effect through colors ( there is no separate parts, which can be styled differently, it is a single bg, which looks tiled because of bg image )
As for “2/9” vertical line - you can have different bg images and switch them through template
horizontal line (12-13) can’t be created through existing styles ( it can be created through bg images - samples\02_customization\03_hours_coloring.html - but it is not a flexible solution , it fixes color without ability change them through css or shift position )
in samples\02_customization\03_hours_coloring.html - special bg image used.
Normal bg image have enough height for one hear and repeats vertically. But you can create a bg image which has height to cover all hours , and you can color it with red color on necessary interval.
I can’t compare hour, to set background for every hour_scale
Yep you can’t set bg for each hour , but you can set some class which has “long_with_12_13_red.png” - bg image which has color marking at necessary height.
scheduler has not native ability to mark scales for specific hours.
existing solution is mostly workaround.
