I want to have a BoxAnnotation where Y1 (- double.Infinity) and Y2 (+ double.Infinity). Basically I wanna specify only X1 and X2. And the behaviour must ensure always the box annotations Y1 & Y2 stretch to visible area even when I resize (zoomout) the chart.

In the screen shot its not stretched.

Hi, I’m trying to position vertical line annotations on a chart. I want to position them on a visible part of the chart, but I need to use the Absolute coordinate mode as I want the annotation to move with the data as the chart is panned or zoomed.

My question is then: how can I find the currently visible extents of the X axis? If the chart is zoomed or panned I need to know what the left and rightmost visible X-axis values are (independent of the data).
