The legend ("key" in Gnuplot speak) is no longer part of the image.
Instead it is a floating&movable overlay.
In the gallery we still use the legend/key in the image.
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.
Generating all images for a gallery view can take
long. It might not be obvious when the computation
is done, because there is no progress indicator.
Fixed by adding a progress bar.
You might want to abort the computation. E.g.
because you already found what you were looking
for or you want to change the parameters.
This can now be done by clicking 'Abort'.
Note, it does not abort the current computation.
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.
