Rotation and perspective
To rotate a 3D chart or view it in perspective, enter the required values
on the Perspective page of the 3D View dialog. You can also rotate 3D
charts interactively; see page 90.
Figure 64: Rotating a chart
Some hints for using the Perspective page:
• Set all angles to 0 for a front view of the chart. Pie charts and
donut charts are shown as circles.
• With Right-angled axes enabled, you can rotate the chart contents
only in the X and Y direction; that is, parallel to the chart borders.
• An x value of 90, with y and z set to 0, provides a view from the
top of the chart. With x set to –90, the view is from the bottom of
the chart.
• The rotations are applied in the following order: x first, then y,
and z last.
• When shading is enabled and you rotate a chart, the lights are
rotated as if they are fixed to the chart.
• The rotation axes always relate to the page, not to the chart’s
axes. This is different from some other chart programs.
• Select the Perspective option to view the chart in central
perspective as through a camera lens instead of using a parallel
projection.
Set the focus length with the spin button or type a number in the
box. 100% gives a perspective view where a far edge in the chart
looks approximately half as big as a near edge.
