matplotlib - Python - color a 3d line plot -


i have 3d line plot of solar spectrum, plotted using command,

from mpl_toolkits.mplot3d.axes3d import axes3d matplotlib.collections import polycollection, linecollection matplotlib.colors import colorconverter, listedcolormap, boundarynorm import matplotlib.cm cm  fig = plt.figure(figsize(15, 8)) ax = fig.gca(projection='3d')  x = spectrumdf['wavelength'] z = spectrumdf['dni'] y = spectrumdf['testnum']  ax.plot(x, y, z) ax.set_xlabel('wavelength') ax.set_ylabel('test number') ax.set_zlabel('intensity')

the resultant plot solid blue , takes whichever individual color give in function: plot( ).

i have been trying create color gradient along z-axis, intensity, without success.

i have around 500 test numbers, each has 744 data points.

thank help!

this wouldn't let me post images because don't have enough reputation. anyway, here's link plot using code https://plus.google.com/106871046257785761571/posts/fmysdf5waqa

enter image description here

using example - line colour of 3d parametric curve in python's matplotlib.pyplot - got scatter plot color gradient along z axis - here's link image of plot - https://plus.google.com/u/0/106871046257785761571/posts/shtsntgqxtw?pid=6133159284332945618&oid=106871046257785761571

enter image description here

i used following command:

fig = plt.figure(figsize(15,8)) ax = fig.gca(projection='3d')  x = filtereddf['wavelength'] z = filtereddf['dni'] y = filtereddf['testnum']  ax.scatter(x, y, z, c=plt.cm.jet(z/max(z)))  ax.set_xlabel('wavelength') ax.set_ylabel('test number') ax.set_zlabel('intensity')  plt.show()

i still working on getting colored line plot because have lot of points, makes scatter plot slow work with.

thank

How to group boxplot outliers in gnuplot -

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
