Japanese Candlesticks with Roassal
by Stefan Krecher
Hi,
I just started to get into Roassal (with Pharo 4.0) with the goal to
visualize financial data like forex charts.
The common visualization is by using japanese candlesticks [1]
Because there is not predefined TRShape/ RTShape, I would need to create
those shapes on my own.
I suspect that this task can't be too complicated but because I'm that very
new to Roassal, I'm asking for some hints and maybe code examples.
The data needed to visualize one candlestick consists of a few numbers, e.g.
20150501 001300;1.120890;1.120910;1.120890;1.120900;0 (-> downloaded from
[2])
First two numbers are Date and Time, the next four Numbers are: open, high,
low, close, that last one is the volume and can be omitted.
There is a bar to describe the price movement (open/ close) and wicks that
describe the highest course and the lowest course during that time frame.
The above data describes a One-Minute-Candle.
So I'd really appreciate if anyone could give me hints or send me to the
right direciction.
regards
Stefan

Fwd: Magritte = Auto-GT Presentation
by Sean P. DeNigris
Hey guys, I asked this on Pharo Dev, but this is probably the right place :)

I'm sorry, I'm still not understanding... I only know how to hook into the
inspector via <gtInspectorPresentationOrder: aNumber>. How does that relate
to GLMMagrittePresentation? How specifically do I have a Magritte
presentation appear by default in GT for an object? Is there an example or
doc somewhere?

Cheers,
Sean

by Usman Bhatti
Hi,
I restored v 3.0.7 in config of glamour because it is needed :).
Name: ConfigurationOfGlamour-usmanbhatti.213
Author: usmanbhatti

restoring version 3.0.7 because we are still loading it for synectique
tools...once we move on to the new release based on Pharo 4.0, we might be
able to clean it up, until then it'll be necessary to keep it.

GanttChartMorph usage and a small request
by Chris Cunningham
Hi. Here's how I'm using GanttChart - for process monitoring, I have some
process that run throughout the day, and I like to be able to see back a
bit how often the fail (or don't run) over the month. For this view, I
group them up at the day period.
Here's the script (picture below):
green := Color green alpha: 0.4.
red := Color red alpha: 0.6.
gray := Color gray alpha: 0.4.
data := {
{ #good. 0. 18. #P1. green. }. { #good. 24. 31. #P1. green. }.
{ #good. 0. 23. #P2. green. }. {#good. 24. 31. #P2. green. }.
{ #good. 0. 8. #P3. green. }. { #failed. 8. 9. #P3. red. }. {#good. 9. 31.
#P3. green. }.
{ #good. 0. 24. #P4. green. }. {#good. 25. 31. #P4. green. }.
}.
b := RTTimeline new.
s := RTTimelineSet new.
s objects: data.
s lineIdentifier: #fourth.
s start: #second.
s end: #third.
s shape fillColor: #fifth.
b add: s.
b axisX
numberOfLabels: 5;
labelRotation: -45;
labelConversion: [ :v | Date year: 2015 day: v + 107 ].
d := RTVerticalTickLineDecorator new.
d shape line color: Color white.
b axisX numberOfDecoratorTicks: 31.
b addDecorator: d.
b open.
[image: Inline image 1]
Each veritcal bar is a day. Did this with
changing RTVerticalTickLineDecorator to check for a different step than the
label step - basically, caused the decorator to use a sub-tick number
(using b axisX numberOfDecoratorTicks: 31 - new method added).
So, the request - is there a correct way to do this?

Label in RTDynamicStackedGrapher
by Miguel Campusano
Hi,
I'm working with RTDynamicStackedGrapher to generate dynamic stacked graph
and I want to add a name on the X axis below every bar.
I see something like this working on RTStackedDataSet with the message
barChartWithBarCenteredTitle: .
There is something working for RTDynamicStackedGrapher?

GLMScriptingEditorTemplate?
by Alexandre Bergel
Hi!
After having loaded Roassal2 in Pharo5, a view cannot be rendered using GTInspector because of some packages that are not loaded by the ConfigurationOfRoassal2. This is easy to fix. However, Glamour-Roassal2-Presentations cannot be loaded in Pharo 5 because of the missing GLMScriptingEditorTemplate.
The class GLMRoassal2Easel depends on GLMScriptingEditorTemplate.
Should I remove GLMRoassal2Easel from Glamour-Roassal2-Presentations ?
Cheers,
Alexandre
