Not sure how this is supposed to work. To be able to support
Angular's development server and Spring as a standalone application
I had to hardcode the port Spring uses.
The problem is, that Angular runs on port 4200. Angular is compiled
to static files. So I cannot dynamically add the port that is
configured for Spring. But Angular has to be able to talk to the
Spring application.
I chose port 17333, because it does not collide with the standard
Tomcat port (8080).
The drop down for plot types should only contain plot types that can
be combined. The reason is, that we can only draw images with two
x/y-axis. Therefore a combination of types that would need three or more
axis is not supported.
We do not know which fields exist at compile time.
But it is a great help to have some pre-selected
fields in groupBy.
Solved by adding a configuration option.
It is (again) surprisingly hard to find a decent date+time-range
picker that works with Angular. Daterangepicker, which I used with
my VueJS application does not work with Angular. I can't get the
angularized version
https://github.com/fragaria/angular-daterangepicker) to work either.
And and a native Angular date picker
(https://github.com/GNURub/ngx-daterangepicker) doesn't work either.
