Subject: plotter scripts: Add automatic x-axis tick scaling
X-Git-Url: http://git.itanic.dy.fi/?p=log-plotter;a=commitdiff_plain;h=d683f195a949f990d96da62caca0ce716d4200b0

plotter scripts: Add automatic x-axis tick scaling

Change the x-tics based on the maximum timestamp. This makes the plot
graphs look better when they are being re-plotter real time during
charging.
