可否在同一个chart下显示两个纵坐标不同的波形？

好像得用对数坐标了耶！如果有的话，哼唧。

All graphs support multiple x- and y-scales, and all charts support multiple y
-scales. Use multiple scales on a graph or chart to display multiple plots tha
t do not share a common x- or y-scale.
Complete the following steps to add a scale to a waveform graph or chart.
1, Right-click the scale of the waveform graph or chart and select Duplicate S
cale from the shortcut menu.
2, To move the new scale to the opposite side of the display, right-click the
new scale and select Swap Sides from the shortcut menu.
3, Associate a plot to the new scale by right-clicking the plot in the plot le
gend and select from the X Scale or Y Scale shortcut menus. If the plot legend
is not visible, right-click the graph or chart and select Visible Items&raquo
;Plot Legend from the shortcut menu.
4, To change the range of the new scale, use the Operating tool or the Labelin
g tool to highlight the end value(s) of the scale and enter a new value. If yo
u set the scale manually, you should disable autoscaling.
