Use this area to assign a second axis to your chart. If a data series is already assigned to this axis, $[officename] automatically displays the axis and the label. You can turn off these settings later on. If no data has been assigned to this axis and you activate this area, the values of the primary y-axis are applied to the secondary axis.
使用此区域在图表中指定一个次轴。如果已经为此轴指定了数据序列，$[officename] 将会自动显示轴和标签。稍后您可以关闭这些设置。如果没有为此轴指定数据序列且激活此区域，那么主 Y 轴的值将被应用到次轴中。
