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:
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
