python - Plot with intermediate colors -

-

i've seen many questions regarding coloring plots, palettes, color maps, etc. want have intermediate colors between default w, m, g, k, b, r.

for instance want plot below gray instead of black. 

import numpy np import matplotlib.pylab plt  = np.linspace(1., 4., 6) b = np.array([3,4.,5.3,7.,8,0])  plt.figure() plt.plot(a,b,'ko-',) plt.show()

you can define colours in many ways matplotlib. docs plt.plot:

in addition [to abbreviations listed above], can specify colors in many weird , wonderful ways, including full names ('green'), hex strings ('#008000'), rgb or rgba tuples ((0,1,0,1)) or grayscale intensities string ('0.8'). of these, string specifications can used in place of fmt group, tuple forms can used kwargs.

so, examples grey in plot:

plt.plot(a,b,'o-',color='grey')  plt.plot(a,b,'o-',color='#808080')  plt.plot(a,b,'o-',color=(0.5,0.5,0.5)  plt.plot(a,b,'o-',color='0.5')

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
