How to Add New Data to Right Y Axis in Existing Graph

  1. Firstly, we need add the new data into current graph layer. There are three methods:
    • Go to the worksheet window, select the second dataset, return to the graph window, and choose Insert: Plot to Layer: Plot Type.
    • Alternatively, data can be selected and dragged from the worksheet and dropped to the graph layer.
    • Alternatively, you can double-click on either the layer 1 icon in the upper-left hand corner of the graph. The Layer Contents dialog will allow you to add or remove data into this layer.
  2. Double-click on the plot you just added to open the Plot Details dialog. With this newly-added plot selected in left panel, go to Display tab, set Plot Data on to Right Y Axis, click OK button to close the dialog. You will see the right Y axis shows and rescales to adapt to the data range of second plot.
