Hi,
I'd like to have separate X/Y scales when zooming.
In other words, I'd like to return {x: true, y:false} from beforeZoom, as this is done in beforePan.
I have two use cases in my project:
- A timeline, where you can chose a date. If the timeline is horizontal, you don't have to scale the y axis, but there is a need to scale the x axis
- A line chart, where i'd like to have different scales on my two axis.
Implementation details:
- Add an option named
enableSeparateZooms, default: false. - If this option is set, each zoom-related options handles {x:, y:}-like zooms, if not set, the current behavior is kept
- Add a method
panZoomToRect({x,y,width,height})to pan and zoom to a specific viewbox, potentially with different x/y zoom factors. width or height may be ommited (but not both), in which case the current scale ratio is kept
What do you think about the idea? Is there anything else to add ? I can try to make the PR if you want.
