Hi Richard,
Plot for last 24 hours, In the FHEMWEB device (its named WEB for my setup, defined as "8083 global", i think this could be changed for different ports).
You can set the "endPlotNow" attribute to 1, then the plot ends with the actual time.
Removing the buttons is not possible, but they could be changed to a size of 0 pixels and this depends which user interface you use. I use floorplan and could change it, BUT this is not trivial and you are stuck using older stylesheets and play around with html attributes in the stylesheet (?) i dont remember right now, too long ago that i changed this.
possibly this could change it, but could be wrong entry in my used css
#diagramm_og_buero_sensor img.Zoom-in { height:0px; width:0px; }
#diagramm_og_buero_sensor img.Zoom-out { height:0px; width:0px; }
#diagramm_og_buero_sensor img.Prev { height:0px; width:0px; }
#diagramm_og_buero_sensor img.Next { height:0px; width:0px; }
diagramm_og_buero_sensor is the name of my svg plot, but this is possibly a wrong version of my tries to fix this for me.
regards
Tux
