I followed the zoom level tutorial of angular. But is not working and also I'm not getting any error.
https://code.daypilot.org/12302/angular-scheduler-zoom
I'm getting an error like ScheduleComponent.html:279 ERROR TypeError: Cannot read property 'start' of null
As far as I can see, there is no .start property used in the HTML template in the tutorial.
I recommend using the attached project as a reference - it runs fine without any errors.
I'm using the licensed version of day pilot 2018. Is I need to upgrade it or I can use it in 2018 also.
The zoom feature is available since version 2019.2.3860, so you'll need to upgrade: https://doc.daypilot.org/scheduler/zoom/
