[need help] about step to step to create Timeline view

finally i found that scheduler work perfectly in my joomla website. But i need create timeline to manager my secretaries. I saw clearly document at : http://docs.dhtmlx.com/doku.php?id=dhtmlxscheduler:timeline. But i don’t know where to add that javascript file. and some one can give me that full file without split code ?
thx

You can try to use an automatically created timeline

Load scheduler’s admin page in joomla, custom fields section, add custom field, set its type as select, add list of options and select “create timeline” checkbox.

include one more extra file << this step i’ve already found one file in component’s source. So where to add " " ???

Unknown Method schedulers::getData() was not found

i always have this red alert at the top of my screen everytime i load into Scheduler component. can u tell me how to fix it ?

this step i’ve already found one file in component’s source
Timeline configuration, which is described in the docs, is related to standalone scheduler, it may be a bit more complicated in case of plugin, there you can’t fully control data processing routines.

I have checked the sources of scheduler, and there is no one occurence of “schedulers” term - so it may be caused by some custom code, which you are using.
