Charter axes scale
by Blondeau Vincent
Hi,
I currently use Charter which is doing nice charts for me. But I experienced some kind of bug with the scales of the chart especially if the values are negatives.
See by yourself:
[cid:image001.jpg@01CFB315.9897E410]
Here the code to draw it:
| b |
b := RTCharterBuilder new.
b extent: 400 @ 300.
b points: { 5 . 6 . 7 .-1 . -3}.
b connectDotColor: Color red.
b interaction popup.
b allY: #yourself.
b stackX.
b axisXWithNumberOfTicks: 4.
b axisYWithNumberOfTicks: 6.
b open.
b view canvas.
Did I make something wrong?
Thanks in advance !
Cheers,
Vincent

Quick Start User Experience
by Sean P. DeNigris
I took the notes below while going through the chapter. In summary:
- maybe RTTabTable is mis-packaged?
- it's hard to keep written examples up-to-date with the code, especially
when they are not automatically tested (of course in my dreams we only have
active essays and never run into this problem, yet I digress...)
- Code comments are key for when users want to drop into the code quickly
from an example in the documentation to adapt it to our own needs
- Nagging thought (not specific to the chapter): most of the Roassal
examples I've seen illustrate procedural scripts. It might be nice to have
more OOP examples, or if the point is to target
non-programmers/Smalltalkers, at least a disclaimer saying that they're in
script form for simplicity of copy/paste or whatever, but a real-world OOP
example can be downloaded at...
Roassal Quick Start says to visualize CSV data starting with RTTabTable, but
shows the table plotted on a map, which does not fit my use case. It seems
like I should be able to use the table not-on-a-map, but I see that it’s in
the Builder-Map package, so I’m not so sure. In the end, that works out okay
because I see that it’s reused in the Timeline example.
Just as an experiment, I adapt the timeline example. Most of it is
straightforward except the send of #normalizeSize:min:max:using: which was
hardcoded and makes my data huge. I’d like to adjust it, but neither the
method nor its class (RTMetricNormalizer) has a comment and I can’t figure
it out from the example senders. Oh, well it was just an experiment…
Next up, the charting example. First hurdle:
#axisXNoLabelledWithNumberOfTicks: does not seem to exist in the system
(fresh download from the link at the start of the chapter). I shorten it to
axisXWithNumberOfTicks:, which works but the resulting chart is overcrowded
with X axis labels. The example now works, but it’s hard to figure out
what’s going on to adapt it to my use. For example, allY: is not a
meaningful name to me and there is no method comment.
HTH.

Chart Builder DSL /Too/ Good?
by Sean P. DeNigris
Roassal is sooo cool! Maybe /too/ cool?! ;-)
I'm having a hard time with RTCharterBuilder. My confusion comes from
everything appearing on the same level, kind of like Amber's html canvas
being magically changed when you enter a tag #with: block. Check out this
snippet for example:
b := RTCharterBuilder new.
...
b interaction popupText: [ :point | point someMessage ].
b points: aCollectionOfPointsOfTypeA.
b connectDotColor: Color green.
b y: [ :r | r newLikes ].
b x: [ :d | d date julianDayNumber ].
...
b interaction popupText: [ :point | point anotherMessage ].
b points: aCollectionOfPointsOfTypeB.
b connectDotColor: Color red.
b y: [ :r | r second * 50 ].
b x: [ :d | d first julianDayNumber ].
The fact that #x: and y: mean different things depending on the order of the
rest of the script is a little "too helpful" to me. I'd much rather have
things that are a property of a particular data set belong to a tangible
object. Something like:
dataSet := RTDataSet new
points: anotherCollection;
connectDotColor: Color red;
y: [ :r | r second * 50 ];
x: [ :d | d first julianDayNumber ].
b addDataSet: dataSet.
The magic confuses other not-so-magical things. Like, afterwards, I tried to
set #popupText: differently for each data set, but they all seemed to be
applied to the both data sets, and were causing errors because the type of
points were different, so I was getting DNUs. Now here was the real cost: I
wasn't sure whether #popupText: was per-chart, or there was some special
ordering necessary e.g. "#popupText: before #points:". This lead to flopping
around followed by giving up. I eventually got frustrated enough that I
hacked in an #isKindOf: in both #popupText: blocks since I couldn't delegate
the #popupText: to the point objects because it was specific to this
particular chart.

Roassal examples process scheduling
by Yuriy Tymchuk
Hi,
I’ve just noticed an interesting thing. When I open roassal examples and then I #fork some block, it’s not being executed. But as soon as I close examples it executes. Maybe some #yield is missing somewhere?

[ANN] Voronyj Diagram
by Natalia Tymchuk
Hello.
I implemented Voronyj diagrams for Roassal. You can read about it here: http://natalia.tymchuk.me/RTVoronyjDiagram/ .
I will be on vacation from Monday till Thursday, but it will be really cool if you can write me your opinion about this project and all your remarks.
Best regards,

Roassal Examples Broken
by Sean P. DeNigris
Should've started a separate thread before...
"CompiledMethod DNU #numberOfLinesOfCode"
The transformation from #numberOfLinesOfCode -> #linesOfCode seems to be
needed in many of the examples throughout Roassal & PBE2.
- RTCharterBuilder examples are broken, mostly because of this
- RTCharterBuilder>>#exampleHistogram seems to have a different problem, not
sure; but possibly redundant because there is another histogram example?

Blueprint diagrams
by Yuriy Tymchuk
Hi,
is blueprint diagram only available in moose panel? Because I want to use it outside of Moose, so I wander if there is some Roassal builder for that.

Inti profiler broken?
by Jan Kurš
Hi,
I tried to load inti profiler, but without success:
Gofer new smalltalkhubUser: 'azazael'
project: 'inti';
package: 'ConfigurationOfInti';
load.
(Smalltalk at: #ConfigurationOfInti) load.
When I run "IntiExamples new openExample" I got an error:
MessageNotUnderstood: receiver of "initializeElement:" is nil
(more in the end of the email).
I tried pharo 3, moose 5 and moose 4.9. None of these were without errors.
What am I missing?
Cheers,
Jan
