Hi, Plasma:
Yes. You are right. We can not put gain and directivity into one plot directly under PatternView. However, you can do it in this way in 2 steps.
1. Display gain in a plot.
2. Select the Save button on the vertical tool bar (not the tool bar upper part below the menu, but the one on the left of the graph). It allows you to save the data of the graph into an XML file.
3. Display directivity in a plot.
4. Select the Open button on the vertical tool bar and provide the saved XML file name.
5. PATTERNVIEW will display both gain and directity together. All the IE3D or other ZELAND PRODUCTS work in this way. You can overlay the curves from multiple graphs together.
Best regards,
