I like to show negative numbers for temperatures, but i only want to show the negatives on the y-axis if it needs to, so if i make the minimum -50 i dont want it to be displayed if it isn't needed. other wise the graphs look awkward with a -50 to 50 C range.
Secondly, when I chart precipitation, if it is fractional (e.g 0.7 mm) it gets a weird prefix on the captions / gprints below the graph, but only if it is below 1.0 mm.
