pybootchartgui: split the output chart into multiple ones
Split the output chart into multiple ones to make it more readable, it only works with "-o path", which means that it doesn't work if the user doesn't want to save the chart to the disk. For example: $ ./pybootchartgui.py /path/to/tmp/buildstats/core-image-sato-qemux86/201205301810/ -f svg -s 5 -o /tmp/ bootchart written to /tmp/bootchart_1.svg bootchart written to /tmp/bootchart_2.svg bootchart written to /tmp/bootchart_3.svg bootchart written to /tmp/bootchart_4.svg bootchart written to /tmp/bootchart_5.svg [YOCTO #2403] (From OE-Core rev: 04a34899e1c15a70babd97a3a59ccb9f8af05bad) Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
