Hi, I'm using the zoom feature of xamDataChart and trying to customize it, please advise:

 I would like the zoom to be only on x axis  , I've set only horizontal and it is works fine

HorizontalZoomable="True" HorizontalZoombarVisibility="Visible"...

1. While dragging on the chart to zoom in, I get a dashed-rectangle based on the position I've started the drag until the end position, but I would like to see only X axis being selected and not Y axis. that is, upper and lower lines of the rectangle should always be on top and bottom of the chart - as there is no meaning to selecting part of the y axis in this case.

2. I want to change the label appearance once I zoom. that is, when the zoomed in range is hour, show time by minute, if range is minute, show seconds, etc. I have the event but I could not find how to calculate the viable range for this matter.

Thanks.
