I am trying to create some charts using the vtkChartXY class. I would like to be able to turn off the feature of zooming in and out of the graph with the mouse wheel button (vtkChartXY::SetZoomWithMouseWheel) but whenever I use that function to turn off the mouse wheel zooming, the tooltip info no longer shows up when I hover over the data points in the chart. Is there a way to keep the tooltips while turning the mouse wheel zoom off?
