Negative values break legend and map

Legend

If you are have a maptable with values that are negative, the legend break. Say our min value is -114 and max is 175. The legend is rendered correctly:

          -114 |---------------------------------------| 175

But when you roll over a country with a negative value, say -77, the legend indicator treats the smallest value as 0 instead of, in our case, -114, thus rendering the marker for the current country off of the legend:

          -114 |---------------------------------------| 175
^
-77

it should put it about here:

          -114 |---------------------------------------| 175
                         ^
                       -77

And, in case ASCII art isn't your thing, here's a screenshot ;)

Map

Countries with a negative value always get a fill color of white. Instead, they should get the fill color of min
