Charter axes scale

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

Re: Charter axes scale

Charter is still in development. Negative values are absolutely not handled so far. However, this is not a big deal to fix. I will work in it today.

Hi Vincent,

Your script was okay. Charter was just buggy.

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

| b values |

b := RTCharterBuilder new.

values := { 5 . 6 . 7 .-1 . -3}.

b extent: 400 @ 300.

b interaction popup.

b points: values.

b connectDotColor: Color red.

b allY: #yourself.

b stackX.

b axisXWithNumberOfTicks: values size.

b axisYWithNumberOfTicks: 6.

b build.

b view

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

Here is a slightly different version of your script (the definition of the interaction is __before__ adding the points).

Another example

Currently, x values _cannot_ be negative. It is not complicated to do (if you need this, and if you have time, then go ahead :-), but I need a bit more time.

Let me this if this version solves your immediate problems. And please, shout if something does not work for you (as you did :-)

Cheers,

Alexandre

Maybe related? The following script starts the first x value way off to the right, even though I thought #stackX just uses 1, 2, 3...
============
data := { { Date yesterday. '3' }. { Date today. '30' } }.

"Charting the data"
b := RTCharterBuilder new.
b extent: 500 @ 400.
b interaction popupText: [ :row | row date julianDayNumber ].
b points: data.
b connectDotColor: Color green.
b allY: [ :r | r second asNumber ].
b allX: [ :d | d first julianDayNumber ].
b stackX.
b axisY.
b build.
b view.
============
3 tested scenarios:
- #stackX and then #axisX - the two x values span from about 3.0 - 4.0, with the axis labeled only from 0.0 to 2.0.
- #axisX and then #stackX - the labels are up to the first date point x value, but the point itself is still shifted more to the right
- only #stackX - no labels, but first point shifted way to right from origin

Then as a sanity check, I manually put -43000 into the first x data point, with only #stackX and it still showed the first point to the right of the origin.

Cheers,
Sean

Re: Charter axes scale

Sean, if you want to stack from left to right your data points, why do you use allX: ?

If you remove the line allX: in your example, then you end up with:

Is this what you expect?

Cheers,

Alexandre
