Simple serial plotter

Features:

• Plotting of multiple variables, with different colors for each
• Can plot both integers and floats
• Can plot negative values
• Auto-scrolls the Time scale (X axis)
• Auto-resizes the Data scale (Y axis)

Incoming serial data should be string. Ending with new line character. Numbers (int and float) can be separated with almost any character. Like: "label2la15be17el28/31/42/54 78\n" or "a2b1.5c1.7d2.8/3.1/4.2/5.4 7.8\n". But not with - unless it is a negative number: "-10\"
