[Moose-dev] Grapher: Set X axis start at custom value

Hello

I am using Roassal2-AlexandreBergel.1335 in Pharo 5.

Most, if not all, Grapher example visualizations starts at point 0 in the X axis. My points are chromosome positions starting at 7,000,000. Is there a way to configure the X axis to start from that position or a custom value? (X label always start at 0 but points does not get rendered until 7M).

If you take the following as example, I would like to start the X axis at 1 approx removing the empty range between 0 and 1.

| b values ds | b := RTGrapher new. values := #(5 6 7 -1 -3). b extent: 400 @ 300.

ds := RTData new. ds interaction popup. ds points: values. ds connectColor: Color red. ds y: #yourself.

b add: ds.

b build. ^ b view
