Thanks for writing.
You can set the zoom and pan after the layout has passed. For example you can add a layout change listener for the first layout and then remove it immediately:
plotWidth = chart.getPlotAreaClip().getWidth();
chart.setPanOffset(-plotWidth * chart.getZoomWidth(), 0);
Unfortunately the chart tooltip can not be shown for an annotation at the moment. We'll consider implementing this for a future release. You will have to manually show a popup if an annotation is tapped. You can use the the previous gesture example and iterate over the annotations checking their layout slots.
We will investigate the DateTimeContinuousAxis issue and will fix it if possible.
Thank you for the feedback, much appreciated.
