I have about two charts on a wavefromGraph to share the same xAxis but different yAxis.i make it follow these:
1) You first need to create several other Y-Axis objects by right-clicking on the WaveformGraph and selecting Edit Y-Axes....
2) Choose the Add button and add however many you like. Click OK.
3) Right-click on the WaveformGraph and select Edit Plots....
4) Choose a particular Plot and click the drop-down menu next to the YAxis property under the Axes category.
But i can't get it.there is only one plot.and the curve which is plotted is usually the Plot[1] .and if i use the same yaxis,it can get two plots.what can i do?
