Creates a graph of any given ObsPy Stream object. It either saves the image directly to the file system or returns an binary image string.
For all color values you can use legit HTML names, HTML hex strings (e.g. ‘#eeefff’) or you can pass an R , G , B tuple, where each of R , G , B are in the range [0, 1]. You can also use single letters for basic built-in colors (‘b’ = blue, ‘g’ = green, ‘r’ = red, ‘c’ = cyan, ‘m’ = magenta, ‘y’ = yellow, ‘k’ = black, ‘w’ = white) and gray shades can be given as a string encoding a float in the 0-1 range.
