Hi all, I'm trying to generate barplots from simple but long (~100000-row) data files, in which each bar will comprise two stacked 'sub-bars'. All the upper sub-bars will have the same hue, and all the lower bars will, likewise, have another uniform hue. However, I wish to specify the luminance (aka brightness) of each bar (i.e., each whole bar comprising two sub-bars) separately, and I wish the plot to render without spaces between successive bars. I've been trying to get thi...

...wing code below to generate a how do I set the h,c, and l values such that the significant, positive residuals appear different on a grayscale printer from significant grayscale residuals. The challenge as I see it is that one can only distinguish the positive and negative residuals with the hue/. Varying the chroma and the luminance only affect the distinctions between large and small and significant and non significant. But my positive and negative residuals are both large (absolutely) and significant, meaning that they will have the same chroma and luminosity, but different h...

Hi All, I'm trying trying to draw a colour wheel (a slice of hcl space) in R. Running the code below doesn't give me what I expect - there's some oddly bright colours of the wrong hue around c(0, 0) and I see three coloured circles (a small magenta, a medium sized yellow and a large cyan). Am I doing something wrong or is there a bug in the hcl code? (Also any suggestions for generating a more evenly spaced grid of colours would be greatly appreciated) Regards, Hadley hcl &...

I want to get a lighter shade of a color...I have a lot of colored objects and want each one printed as a foreground against a slightly lighter background. I thought I could try something like changing the alpha channel by first converting it to rgb. But prior to trying that, I'm stuck with how to get the color after converting using col2rgb() to be interpreted again as a color, rather than

Hello, you might remember me from the previous problem with X :) I found out what I did wrong, I had installed from a CVS, but not usign the install script, which helped out alot with the config file. this time however, when I ran zmud.exe , it complained that the directory, /windows/Fonts . diddnt exist (which it doesnt), So I created the directory, to see what it would do, and then it just

...be able to view differences in the data. I've tried messing with RGB values, Brewer palettes, etc. How can I select colors from a list of available colors without choosing ones which are too close in similarity to each other. For instance, I could have several very similar blues, but if the Hue or saturation was different on each, it would be fairly easy to tell the difference? Maybe there are too many factors to make this visual representation effective?

Hi has anyone coded up domain colouring for visualizing complex analytic functions (such as elliptic functions)? [ the idea is to depict a complex function f(z) using a filled.contour() variant in which the hue is given by Arg(f(z)), and the saturation by Mod(f(z)). ] -- Robin Hankin Uncertainty Analyst Southampton Oceanography Centre European Way, Southampton SO14 3ZH, UK tel 023-8059-7743

...o an interval) or at least ordinality. I have experimented with the following: Bcolors <- hsv(.6, seq(0.2, 1, length=5), 1) Fcolors <- hsv(seq(.1,0, length=5), seq(0.2, 1, length=5) this is what you see in the plot. What colors would you use? Do you think that varying both brightness and hue helps to distinguish colors? Should I change saturation, too? Thanks, Tamas PS.: The plot is simply gzipped.

...colours to rgb, when you can set the opacity. I have found the function col2rgb(), which works in the sense that it gives a vector of numbers but these don?t work directly in rgb because they are too big. If I divide through to make them all less than 1 I don?t get the corresponding colour-blind hue, but something somewhat off.
