#35 Bars with other color for negative values

When we have negative values in a bar chart, could it be possible to have diferent colors for the bar? I mean, show it, for example, blue when the value is positive, and red when is negative...

You could color bars differently through data file. See the \data-files\bar-glass-2.txt for example a pair of red bars. When you generate the data file, you could watch for negative values and color it differently.
