Hi,
On a related matter, there is any way to make axis be numbered according
to the type of data, por example using integer data points will set the
axis as integers (like in the first example) but adding a 3.5 will make
the axis scale like is now. I don't know if this default makes sense (it
does to me).
Cheers,
Offray

Hi Thomas,
This is a tricky situation, for which I have found a solution.
Consider the script
-=-=--=-=--=-=--=-=-
b := RTGrapher new.
d := RTData new.
d points: #(3 4 5).
d barShape.
b add: d.
b axisX noLabel; noTick.
b
-=-=--=-=--=-=--=-=-
produces
As always.
You can now send #noAlignmentOffset to the data to remove the offset.
-=-=-=-=-=-=
b := RTGrapher new.
d := RTData new.
d points: #(3 4 5).
d barShape.
d noAlignmentOffset.
b add: d.
b axisX noLabel; noTick.
b
-=-=-=-=-=-=
produces:
It is visually less appealing, however it works well when you combine
it with other data sets:
-=-=-=-=-=-=
b := RTGrapher new.
d := RTData new.
d points: #(3 4 3.5).
d barShape.
d noAlignmentOffset.
b add: d.
d := RTData new.
d points: #(3 4 3.5).
d connectColor: Color red.
b add: d.
b
-=-=-=-=-=-=

Hi Alexandre, hi Milton
today I upgraded to the new version 2.35 of Roassal for Visualworks.
It gets better each time!
Unfortunately we have an issue with the new RTData. As the old
RTStackedDataSet is obsolete now, we moved all our charts to RTData.
In some charts where we have bars mixed with lines, the dots of the
line graph are no longer aligned with the center of the bars, as it
was before with RTStackedDataSet. If I change the RTData for the line
graph to RTStackedDataSet, the alignment works again.
Here is an example script:
| b ds |
b := RTGrapher new.
ds := RTData new.
(ds barShape)
width: 15;
if: [:v | v < 0] fillColor: Color red;
if: [:v | v > 0] fillColor: Color green.
ds points: #(5 -6 10 20 -9).
b add: ds.
ds := RTStackedDataSet new.
ds
points: #(4 -2 11 16 -10);
connectColor: Color red;
connect.
ds dotShape color: Color blue.
ds lineShape color: Color blue.
b add: ds.
ds := RTData new.
ds
points: #(4 -2 11 16 -10);
connectColor: Color red;
connect.
ds dotShape color: Color red.
ds lineShape color: Color red.
b add: ds.
(b axisX)
noLabel;
noTick.
b axisY noDecimal.
b build.
b view
In the example, there are two lines with the same values, one using
RTData, and one using RTStackedDataSet. And they have different
positions, while I think they should be aligned.
Maybe you can have a look at that?
Thanks,
Thomas
