I'd like to create a plot (just data points) where the x-values are dates like yyyy-mm-dd (no time needed, just day). The dates aren't consecutive, just various jumbled dates.
Looking at the docs for some of the various alternatives (GD::Graph, Chart::Gnuplot, Chart::Clicker, Chart), I don't see any mention of being able to automatically use dates (I want them to be treated like regular numerical values).
I suppose I could convert the dates to epoch times using DateTime, but then I'd have a plot showing epoch times in the x-axis instead of dates, but that would be difficult for readers to make sense of.
Should I used Datetime and fiddle with trying to convert date values and manually setting plot tick values, or can one of the plotting / charting modules do this for me?
