Interpretation of Negative values

#1

Hello,

I wanted to know what does the negative values in the transmission monitor mean? What is the unit along Y-axis? Can I save the data and offset it to bring the graph above x-axis?

Thanks

Dear @rumman18

If the power passes the monitor in the positive x (or y or z) axis, we assume its positive other wise the value will be negative:

These plots are normalized to injected source thus y axis is the normalzied power passes through the monitor.

Yes, you can.

Please refer to our getting started examples, watch some of introductory webinars, and take a look at scripting language tutorial. These should give you a comprehensive knowledge how to get onboard with the software.

Thanks
