For example, if the <tt>xunits</tt> and <tt>yunits</tt> fields of the input AOs are set, these labels are used on the plot labels. </p> <p> In addition, <tt>iplot</tt> can be configured using a input <tt>plist</tt>. The following examples show some of the possible ways to use <tt>iplot</tt> </p> <div class="fragment"><pre> >> a1 = ao(plist(<span class="string">'tsfcn'</span>, <span class="string">'sin(2*pi*0.3*t) + randn(size(t))'</span>, <span class="string">'fs'</span>, 10, <span class="string">'nsecs'</span>, 20)) ----------- ao 01: a1 ----------- name: None data: (0,0.887479404587351) (0.1,-0.449797172615395) (0.2,0.479022102390939) ... -------- tsdata 01 ------------ fs: 10 x: [200 1], double y: [200 1], double dx: [0 0], double dy: [0 0], double xunits: [s] yunits: [] nsecs: 20 t0: 1970-01-01 00:00:00.000 ------------------------------- hist: ao / ao / SId: fromTSfcn ... $-->$Id: ao ...
