Sparkline collapses for some datasets if plot height is 30 or lower

Hi Alexander, I'm looking into it. Charts with small dimensions have issues with axes collapsing, probably due to chart margins or something.

In the meantime I suggest you use larger dimensions to generate the image and then set the image size in html/css.

This issue has been resolved :)

30 pixels is not a pivot point. The proportion of the spark to the height of the plot is changing:

31 pixels:

40 pixels:

50 pixels:

100 pixels:

300 pixels:
