<p class="MsoNormal">Hi,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Does anyone know how to define a piecewise linear function in LON-CAPA, and plot it with gnuplot? And, a related question: How do you put plots next to each other?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I need to display a plot of voltage on one graph, with a plot of phase-angle-fired half-sine current right below it on a separate graph, but using the same horizontal axis values and scale. The multiplot command in gnuplot allows multiple
plots next to each other, similar to MATLAB, and the ternary operator allows definition of piecewise linear functions, but I don’t know how to implement either of them from within LON-CAPA.<u></u><u></u></p>
