Changing histogram stack in qplot

Hi Jason,

You'll need scale_fill_manual(values = c(low = "blue", middle =
"black", high = "red"))

See http://had.co.nz/ggplot2/scale_manual.html for more examples/details.

Regards,

Hadley
I've been using qplot pretty successfully to generate stacked histograms.  However, it appears that I need to tweak the colors a little.

I've got three temperature variables (characters not numeric) and I need to change from the default qplot colors to the following:
Low = Blue
Middle = black
High = Red

Here is pseudo code of what I have currently:qplot(Run, data = TestData, breaks = hist_breaks, ,
          fill = TestData$Temperature,
          main = short_title) +
          scale_x_continuous("Run, Radians") + scale_y_continuous("Frequency") +
          scale_fill_discrete("Temperature")

Thanks for any advice and insights.
