Wrong x-axis upper limit with date ? about gadfly.jl HOT 6 CLOSED

Coord.cartesian(xmax=...

or Scale.x_continuous[maxvalue=....

it's not a bug per se. there is an optimization algorithm which computes the bounds and number of ticks. ideally we need to figure out a way to hoist the parameters (ie granularity_weight, simplicity_weight, coverage_weight, and niceness_weight) into a user accessible function instead of just hard-coding defaults.

Using integer instead of date gives a result much more satisfying for the end-user:

d = DataFrame(date = [23, 22, 21, 20, 19, 18, 17, 16, 15, 14],
              result= [0.37, 1.66, 0.1, 2.64, 0.6, 3.73, 0.74, 5.69, 1.82, 2.93])
plot(d, x=:date, y=:result)

Is it the expected behaviour that bounds are different for date and integers in this example ? Thanks !

a lot of changes were made to dates recently and there hasn't been a new release made to include them. try checking out master (with ] dev Gadfly) and see if the ticks are any better for you. i get the following plots on master for your two examples above:

Thanks for your quick answer ! It does fixes my issue, closing it now.
