Plot widget

A plot widget embeds a dynamic plot into the canvas. Around the outside of the plot are a number of input ports that can be wired.

left hand edge

Up to 4 quantities can be plotted on the graph simultaneously, with line colour given by the colour of the input port

right hand edge

Another 4 quantities can be added to the plot. These are shown on a different scale to the left hand inputs, allowing very different magnitudes to be compared on the one plot.

bottom edge

Quantities controlling the $x$-coordinates of the curves. The colours match up with the colour of the pen being controlled.

If only one bottom port is connected, then that controls all pens simultaneously, and if no ports are connected, then the simulation time is used to provide the $x$ coordinates

corners

Corner ports control the scale. You can wire up variables controlling minimum and maximum of the $x$, $y$ and right hand $y$ axes. If left unwired, the scales are determined automatically from the data. This can be used, for example, to implement a sliding window graph
