This is a placeholder bug for the work mfisch is doing (going to do) to fix bootchart and make it work "out of the box". Once I get back to this, I'll post more details on what's wrong and how I plan to fix it.
Bootchart2 needs more investigation. Since it actually has a bootchartd that you change with the boot arguments it's possible that the daemon never stopped and that means you don't get data.
For bootchart2:
To see the kernel boot options:
sudo abootimg -i /dev/mmcblk0p2
To modify them:
abootimg -u /dev/mmcblk0p2 -c cmdline="foo bar baz"
