The smithchart function returns a handle to the Smith chart object and, optionally, a vector of lineseries objects. The smithplot function returns only a smithplot object, which enables you to easily control plotting features. For example, consider the following code.

The following code produces an equivalent Smith chart using smithplot instead.

If your code uses the lineseries or smithchart handles, rewrite your code to use the equivalent properties of smithplot. For example, to replace the smithchart property Value, use 'GridValue' in the call to smithplot.

Otherwise just replace the call to smithchart with a call to smithplot.

For more information, see smithplot in the RF Toolbox or Antenna Toolbox documentation.
