I was wondering if there was a way to get the trackball to snap to the closest point by taking only the horizontal distance into consideration?
We have a chart with a number of series which all have the same set of x values. We have the trackball behavior enabled and what we would like to be able to do is to show details about each series but for one x value at a time. The default behavior seems to get the closest points for each series by taking the closest point to the mouse. This means, depending on mouse location, that the trackball can be showing values from 2 points which have different x values. Is there a way to stop this and to get the trackball to snap only to x values?
