Hi!

Roassal supports Whisker plots, but not exactly candlestick.

You can try this:

-=-=-=-=-=-=-=-=-=-=-=-=
| b createList r |
r := Random new.
createList := [ :size :d1 :d2 | (1 to: size) collect: [ :i | d1 + (r next * 
(d2-d1))] ].

b := RTGrapher new.
(1 to: 10) do: [ :i | | ds |
        ds := RTBoxPlotDataSet new.
        ds points: (createList value: 20 value: 0 value: 20).
        b add: ds.].
b
-=-=-=-=-=-=-=-=-=-=-=-=
 
Which produces:



Another example:
=-=-==-=-==-=-==-=-==-=-==-=-==-=-==-=-==-=-==-=-=
        | b ds |
        b := RTGrapher new.
        b extent: 400 @ 200.
        RTShape withAllSubclasses
                do: [ :cls | 
                        ds := RTBoxPlotDataSet new.
                        ds points: (cls rtmethods collect: 
#numberOfLinesOfCode).
                        b add: ds ].
        ^ b
=-=-==-=-==-=-==-=-==-=-==-=-==-=-==-=-==-=-==-=-=

Which shows the distribution of methods size in Roassal


Cheers,
Alexandre
