No - there currently no functionality for this.
Thanks for the kind words.
This works: ``` haskell import Graphics.Rendering.Chart.Easy import Graphics.Rendering.Chart.Backend.Diagrams import Data.Time.LocalTime import Prices(prices,mkDate,filterPrices) prices' :: [(LocalTime,Double,Double)] prices' = filterPrices prices (mkDate 1 1 2005) (mkDate 31 12 2006) fileopts = fo_format...
Sorry you had the problem. I've updated this documentation: https://github.com/timbod7/haskell-chart/wiki/How-to-use-backends
I'm interested too - Is this still a problem?
Hmm. Do you still see the same problem if you import `Graphics.Rendering.Chart.Axis.LocalTime` explicitly? On Tue, Aug 25, 2015 at 5:17 AM, peterljung [email protected] wrote: > No, I haven't been able...
I'm at a bit of a loss here. I don't see why this instance for Double can be found ok: https://github.com/timbod7/haskell-chart/blob/master/chart/Graphics/Rendering/Chart/Axis/Floating.hs#L44 whereas this corresponding instance for LocalTime is not found...
It's good that you've got it working. The error you are seeing is quite surprising.
This actually came up on reddit recently: https://www.reddit.com/r/haskell/comments/3a21tx/color_mapheat_map_plotting_without_gnuplot/ It wouldn't be too hard to add. There's actually a long running pull request for contour plots (https://github.com/timbod7/haskell-chart/pull/47). I haven't merged it...
Also, an older discussion on heatmaps on the mailing list: http://projects.haskell.org/pipermail/chart/2012-May/000028.html
