I want to show a "success"/"failed" value on a chart in a compact space. Basically I have various processes that run every day. I want to show in a compact space the status history of each process.
The purpose of the chart would be to alert the user to problems and provide a launch for them to drill down into a particular process that they see had failed recently (even if it was recently successful).
Here's an example of an idea I just made in paint:
I think you could use sparklines as a compact visualization tool.
This view is not precise, but it allows to view errors distribution and total error count for each process. More precise information is displayed in process specific screen.
Light grey bar is an observation time window (a week or two, etc.). Dark line is an error occured within observed period. It's placed according to its occurrence time: today's error is placed rightmost an so on. So you could perform simple visual analysis of recently failed processes.
Probably you'll pay more attention to the faulted processes, which have more dark lines closer to the right side (more recent): 
– this that I've called the distribution.
Take a look for the animation, each frame is a day:
I'm wondering if the success/fail values in your graph have the same properties as those generated by a continuous integration server:
If so, you could bundle "runs" of the same status together in the chart, something like this:
(The righthand five bubbles show the same sequence as your original demo.)
These could be stacked in a number of ways to cover your 3+ processes; the exact technique would depend on whether the processes were coupled or independent.
Alexey's idea is clean and straightforward- made me think of this image from my Fitbit flex. Sort of what Alexey was proposing, but with some additional information in the form of a hover- giving specifics.
