Graphing PWM values (for servo control) using something like the I2C view ontop of graph

I have an idea for a robotic / servo project, but i want to be able to watch the values coming out of my control program before i attach the servos or escs to control motors. It would be nice to verify the hardware wiring is correct using a tool like your logic analzyer.

While watching the EEVBlog(aka Dave Jones) another awesome Aussie who happens to live nearby i was impressed by your softwares graphing of i2c traffic and the annotations added to the bytes that travel back and forth. Something like the i2c ui for PWM would be great and save us the trouble exporting and doing stuff in XL.

    This would be beyond useful to me - I work with UAV systems that use a lot of PWM protocol in servo and ESC systems. Something that displayed the PWM width in us and the PWM period next to it would be great. I bought my Logic 8 pro to probe SPI, I2C and PWM, and I was quite surprised to find PWM support was fairly minimal. I guess Australians love PWM!
