This package provide a function to create a sparkline graph. Sparkline graphs were introduced by Edward Tufte see http://en.wikipedia.org/wiki/Sparkline They are charts containing a single line without any labels or indication of scale. They are meant to be used inline in text, without changing the line height and provide a quick overview of the trend and pattern of the underlying data. Creating sparkline graphs is done for example by (sparkline-make-sparkline 80 11 '(10 20 4 23.3 22.1 3.3 4.5 6.7)) which creates in image which can be inserted in a buffer with the standard image functions such as: (insert-image (sparkline-make-sparkline 80 11 '(10 20 4 23.3 22.1 3.3 4.5 6.7))) GENERAL DRAWING FEATURES Besides creating sparklines this package also allows creating and drawing into bitmaps in a limited way. The supported features are: - Creating a monochrome bitmap of arbitrary size with `sparkline-make-image' - Coloring a pixel in the foreground or backaground color with `sparkline-set-pixel' - Drawing straight lines with `sparkline-draw-line'.
