Starting y axis at 0 on line graph

Starting y axis at 0 on line graph

Hi,

Is it possible to change the default start point of a y axis on a line graph to 0 and not the minimum detected value? I can see that you can manually define the start and end of the range but this means that if I manually define the start as 0 then I also have to continually update the upper range limit when the data is refreshed.

Cheers,

James
