coloring histogram or boxes *with errors*
the histogram examples are amazing ; however, i cannot see how to
incorporate error bars into those examples, and i cannot see how to
simply color my histogram bars differently. it looks like i have to
rewrite my data and script from scratch, but i am bewildered by the
possibilites - newhistogram, boxes, xtics,... i don't know where to
start. in particular, i want to use the 'awk<' trick and keep the
labels as implemented in the example i have :
data file "example.dat":
1 0 0 2.8673 0.2047 experiment1
2 0 0 2.2550 0.6326 experiment2
3 0 0 1.0238 1.2356 experiment3
4 0 0 1.5366 0.9208 experiment4
gnuplot commands :
reset ; set xrange [0:5] ; \
set xtics 1 ; set grid ; \
set key left top ; unset label ; \
set xlabel "experiment" ; set ylabel "average +/- sigma " ; \
set style fill solid border -1 ; \
set style data histogram ; \
set xtics nomirror rotate by -25 ( \
"experiment1" 1, \
"experiment2" 2, \
"experiment3" 3, \
"experiment4" 4 ) ; \
plot \
"< awk '{print $1, $4, $5}' example.dat" w boxerror notitle lw 2 lt 1

In this example both the "awk trick" and the explicit xtic setup are
unnecessary. There is also little point in chaining all the commands
into one line with the backslashes (unless you want to use that line
as a command line argument to -e).
It is better to select the columns you want to use with the 'plot ...
using' mechanism, this is more efficient and also more portable (works
on systems that don't have awk). For the labeled xtics there is the
xticlabel function.
reset
set xrange [0:5]
set xtics 1
set grid
set key left top
unset label
set xlabel "experiment" ; set ylabel "average +/- sigma "
set style fill solid border -1
set xtics nomirror rotate by -25
plot 'example.dat' u 1:4:5:xticlabel(6) w boxerror notitle lw 2
So far this is equivalent to your example. Now you want each box to be
colored differently.
This is possible with some of the new features of version 4.4:
plot for [i=3D0:3] 'example.dat' u 1:4:5:xticlabel(6) every ::i w
boxerror notitle lw 2
Finally, here is a variant that allows you to define arbitrary RGB
colors:
colors =3D "#226699 #aa5544 #9911bb #ccdd44"
plot for [i=3D0:3] 'example.dat' u 1:4:5:xticlabel(6) every ::i w
boxerror notitle lw 2 lc rgb word(colors,i+1)
It is also possible to define line styles, like
set style line 10 lw 2 lc rgb "pink"
set style line 11 lw 2 lc rgb "light-blue"
set style line 12 lw 2 lc rgb "brown"
set style line 13 lw 2 lc rgb "dark-green"
plot for [i=3D0:3] 'example.dat' u 1:4:5:xticlabel(6) every ::i w
boxerror notitle ls i+10
Also see 'help colorspec'.
Hope this helps.

Plotting color graphics with a color bar
I've been using 'image' to plot 2d data, but have run in to problems when adding a color bar. The data is in the range from 0 to 3nm, and a colorbar fitted to this has only four shades. I can scale the data so it's 0 to 255, which gives a lovely image, but then the color bar is also from 0 to 255. I can't see how to add a different scale to the colour bar. Some plot functions use color as another axes, and by scaling this axes the color bar scales as well. However, I don't think 'image' can in this way. Is it better to use another plotting function than image? I need to maintain the aspect ratio of the plot, as it represents physical sizes. I want to keep a flat 2d image (for now), although later will need to plot the third variable as 3d height as well as color. Thanks for any help, Richard. I think "imagesc" is the command you are looking for. Richard Cobley wrote: > > > I've been using 'image' to plot 2d data, but have run in to > problems > when adding a color bar.

How to handle the color for graphics for two-color printing?
Newbie question. The publication needs two colors, red for titles and green for texts. I also placed a few cliparts that I created with Illustrator in the article. Each clipart should be either red or green too. What I did is I colored the cliparts in green and red in Illustrator and saved them as EPS files. Then placed them in the article. When I tried the plug-in, save for service provider, it says it will be 4-color printing. I suspect the color that I used for EPS files in Illustrator may not be the exact green and red for the titles and texts. Am I right? If so, how to correct th...
xdvi foreground and background colors that changes graphics colors
Hi! I am using LaTeX to create slides for a presentation (using FoilTeX), and I have a problem with colors and included graphics. The simple way I use to change the background color and text color is with the -bg and -fg options of xdvi (the version of xdvi available here (22.40) doesn't render colors), but it turns out that any black and white pixels in images are also changed to the new background and foreground colors! Is there anything I can do other than editing the images such that black and white pixels won't be black and white but almost black and almost white? -- F....

Is it better to use another plotting function than image? I need to maintain the aspect ratio of the plot, as it represents physical sizes. I want to keep a flat 2d image (for now), although later will need to plot the third variable as 3d height as well as color. Thanks for any help, Richard. I think "imagesc" is the command you are looking for. Richard Cobley wrote: > > > I've been using 'image' to plot 2d data, but have run in to > problems > when adding a color bar.

How to handle the color for graphics for two-color printing?
Newbie question. The publication needs two colors, red for titles and green for texts. I also placed a few cliparts that I created with Illustrator in the article. Each clipart should be either red or green too. What I did is I colored the cliparts in green and red in Illustrator and saved them as EPS files. Then placed them in the article. When I tried the plug-in, save for service provider, it says it will be 4-color printing. I suspect the color that I used for EPS files in Illustrator may not be the exact green and red for the titles and texts. Am I right? If so, how to correct th...
xdvi foreground and background colors that changes graphics colors
Hi! I am using LaTeX to create slides for a presentation (using FoilTeX), and I have a problem with colors and included graphics. The simple way I use to change the background color and text color is with the -bg and -fg options of xdvi (the version of xdvi available here (22.40) doesn't render colors), but it turns out that any black and white pixels in images are also changed to the new background and foreground colors! Is there anything I can do other than editing the images such that black and white pixels won't be black and white but almost black and almost white? -- F....

When is an error not an error?
The Java language specification claims in: 8.8.7.1 Explicit Constructor Invocations .... "If an anonymous class instance creation expression appears within an explicit constructor invocation statement, then the anonymous class may not refer to any of the enclosing instances of the class whose constructor is being invoked." Helpfully it gives an example: "For example: class Top { int x; class Dummy { Dummy(Object o) {} } class Inside extends Dummy { Inside() { super(new Object() { int r = x; }); // err...

color of histogram
Hi I wonder how I can change the color of the histogram to be transparent with red edge color. [ n, ctrs ] = hist( log(SaCap_g ) ); or bar( ctrs, pdfheight, 'hist' ); Paul > I wonder how I can change the color of the histogram to be > transparent with red edge color. Paul, you can call hist and bar to get a handle to the histogram, then set its various properties as follows: load carsmall [n,x] = hist(MPG); h = bar(x,n,'hist'); set(h,'facecolor',[.8 .8 .8], 'edgecolor','r', 'facealpha',.3) You can also type "get(h)" to see ...
