Details:
I've noticed that when the X data is floating point with lots of decimals, the
line and dotted line plots generated using "fltk" are misaligned, and even
worst, the lines and dots moves randomly as you resize the plot window.
This behavior is not exhibited when using "gnuplot".
Here is a simple piece of code that would reproduce the error:
plot([7777777.0, 7777777.1], [1,2], ".-")
I found the problem when trying to plot time series in which the x axis
contain the date as the number of days since January 1st 0000, as returned by
the function "datenum".
