Charting in Roassal2

Hi Folks.

Can anyone tell me whether we have candlestick-charting ability in Roassal2?

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.].

-=-=-=-=-=-=-=-=-=-=-=-=

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

Thank you , Alexandre. That’s exactly what I needed to know. Adapting the whisker plots should be straightforward.
