Custom plot example

This example shows how to create a Custom display script window to display a scatter plot from any number of input signals. This code is used by a custom tool "Scatter plot 2D".

A number of different plotting parameters can be set in the script. Those will be used in the calls of Julia plot function.

The script excepts only an even number of input signal parameters. For each pair of input windows, it adds a new series to the plot. Please note that the first pair of windows is used to create a new plot (plot(...) function call). Subsequent window pairs are used to add new series to an existing plot (plot!(...) function calls).
