I have some data from a database (SQLite), mapping a value (an integer) to a date. A date is a string with this format: YYYY-MM-DD hh:mm. The dates are not uniformly distributed. I want do draw a line graph with the dates on X and the values on Y. What is the easiest way to do this with Perl?

I tried DBIx::Chart but I could not make it recognize my dates. I also tried GD::Graph, but as the documentation says:

GD::Graph does not support numerical x
axis the way it should. Data for X
axes should be equally spaced

    You can drive gnuplot using Chart::Gnuplot.

    Alternatively, if SVG is an acceptable output format, there is SVG::TT::Graph.
