labelConversion: in latest Grapher

Hi,

I’ve launched my oldish project, and encountered an issue with new grapher. When one uses #labelConversion: he has to define an axis label for a certain index of dataset. But in latest Grapher this index can exceed the total number of dataset entries. While this is not an issue for continuos data, I am experiencing problems when I want to graph readings in a stacked manner. For example I have data readings taken in a different moment of time, and I wan to label the index of a reading and it’s time, to give and idea where in time it is, but when I’m asked about the label on 4 indices after my last reading I cannot put there anything.

Hi Yuriy,

Can you provide a code snippet please? It would help to really grasp the problem :-)

Cheers,

Alexandre

Re: labelConversion: in latest Grapher

Ok, look at something like this:

| b ds items |

items := (100 to: 0 by: -5) asOrderedCollection.

b := RTGrapher new.

b extent: 500 @ 100.

ds := RTStackedDataSet new.

ds points: items.

ds y: #yourself.

ds barShape.

b add: ds.

b axisX

labelConversion: [ :index |

(items at: (index min: items size max: 1)) asString ].

b build.

b view

In my case I put time values on x axis. As you can see 0 in the end is really misleading. In the previous axis of grapher last tick was placed right on the last element.
