A Boolean Chart has been suggested. I want one too.
This should have a line that looks like a square wave changing between the binary values.
The Y axis should be capable of being labeled for the 2 states in text so you can name the 2 states.
A bonus would be to be able to stack up more than one binary data stream in the same chart, like a multi trace digital scope screen, and label them accordingly. The important theing here is that the timescales line up for the streams.
An alternate is to have the streams each in its own chart but have the timescales capable of being synchronized so that the events can be correlated.
You can see this 2 state chart looks nasty with the slopey lines. The last value should be maintained until the new value comes.
Another option would be to use the analog chart but make the data stay at the last value until a new value is obtained then step to the new value as a chart option. THis would do it too. Suppressing the decimal points on the 1/0 Y axis would also be needed.
Thanks
