Refresh line chart and legend to initial view

Phil7G

Hi,

i've got a line chart that is filled by user choices in selection lists. The three selection lists (hierarchy exists - 1st list choice determines what choices can be made in 2nd list and so on) are getting filled by different select statements, each one has a seperate table as source (assignments are determined via IDs). My line chart is refreshed whenever a choice is made in the selection lists via dynamic action (Event: change). So far, so good - everything works fine till this point.

When the chart is refreshed, I would like to get the initial view, just as a user made a choice in the selection lists. The legend does not get refreshed and keeps the setting for "hide/show" once modified before and the view in the chart stays at the same zoom level as before.

Is there a way to refresh the chart and legend and come up with the initial view?

I would really appreciate any help!

Cheers,

Phil

Didn't come up with a real solution, but took another route with a workaround: I'm generating the link via javascript location.assign( ) method dynamically and fill in the user's choices in the selection lists. This way, the page is reloaded everything works fine.

I was able to find what is causing my problem: The different objects I have in my database-table rows which are queried to fill my chart have timestamps. These timestamps are the values on the x axis (so to speak my time line). The process of recording the values for the objects started and in some cases ended at different points in time. When I zoom in the chart at, let's say, 1st of March 2020 and then refresh the chart by choosing a different object in the selection lists, for which the data recording started later (e.g. 1st of December 2020), I don't see any data in my zoomed-in view. Furthermore, the overview seems so behave a little buggy: When navigating via the overview, it is not corresponding to the main view anymore.

This is why I'd like to try to refresh to a max zoomed-out view when refreshing my chart - or rather show the data for all the records over the different periods of time for the objects without loading them and still being stuck at a point of time from the previous shown object that doesn't exist in the data of the currently chosen object.

In addition, I would appreciate any other idea to solve this problem as well, of course! ;-)
