the linechart does not seem to draw values of 0. When I have a series of values, every 0 is ignored and the linechart just draws a line between the non-zero values.
Graylog version is: 3.1.3
I reproduced this with a simple count(), but I happens on all data containing values of 0:
I can only attach one screenshot. If you switch visualization type to data table it shows mutliple rows with a count of 0.
This way of drawing the graph gives a severely false impression of the actual data.
