replace(plot,frequency,data)

Description

example

replace(plot,data) removes all current data from a Smith chart, plot, and adds new data to the Smith chart.

replace(plot,frequency,data) removes all current data and adds new data to the Smith chart based on multiple data sets containing frequencies corresponding to columns of the data matrix.

Examples

Open Script

Read S-parameter data.

amp = read(rfckt.amplifier,'default.s2p');
Sa = sparameters(amp);
smithplot(Sa,[1,1],'LegendLabels','S11 at 50 Ohms');

Plot S-parameter object with a new impedance of Z0 = 75 Ohms.

Sa = sparameters(Sa,75);
S11 = rfparam(Sa,1,1);
Freq = Sa.Frequencies;
s = smithplot('gco');
replace(s, Freq, S11);
s.LegendLabels = 'S11 at 75 Ohms';

Input Arguments

collapse all

Smith chart handle, specified as a plot handle. If the handle of the Smith chart is not retained during creation, use p = smithplot('gco').

Input data, specified as a complex vector or complex matrix.

For a matrix D, the columns of D are independent datasets. For N-by-D arrays, dimensions 2 and greater are independent datasets.

Data Types: double
Complex Number Support: Yes

Frequency data, specified as a real vector.
