We are using vtk.js, and when visualizing 3D data with isosurfaces, the tick values on the x and y coordinate axes appear enlarged due to scaling. We want to restore the displayed values to their original scale without modifying `DataBounds` (only changing the display). Is it possible to reset the tick values shown on the axes? When trying the `vtkCubeAxesActor` object, we found that many methods, such as `setTickPositions`, `setTickLabelGenerator`, and `setScale`, are not available. Which method should we use to achieve this?Thanks.
