Hello, I have a selectable line chart, so the user can zoom in and out. However, it is almost impossible to zoom on the points near the border, because when the cursor exits the chart area, the selection stops. This also happens with the zoomable chart in the gallery, so I assumed it is a bug. I would be glad though if there were a hidden feature to change this behaviour.
Selecting the elements even near border works fine. But still if it create troubles you can manually increase the viewPort by setting viewportMin and viewportMax so that the dataPoints will be far away from border.
