This patch adds a command line option for timechart that allows the user to specify the width of the SVG file. This patch also makes sure that each second of recording has at least 200 units (pixels at 96 DPI) of width. This impacts recordings longer than 5 seconds; recordings shorter than 5 second will scale up to have a width of 1000 units for the whole recording (as before).
