ZedGraph data points are received through the IPointList interface. If you look at this interface, you will see that you can create any kind of data structure you want in your own custom class. All your interface needs to define is an indexer into your data structure. So create your own class that implements IPointList. Then write your code that updates the data inside your class using the logic you described with start and stop functionality. Call AddCurve on the GraphPane and pass in your IPointList...

Peak Counting is typically a local maxima problem. The simplest algorithm divides the time into discrete intervals. For each interval, find the maximum. You will then have one peak for every interval. Then you can plot your peaks. There are other algorithms that get more sophisticated, but how you do it depends on exactly what you consider a peak. For instance, you may want to only count a maxima as a peak if it has a sharp angle that exceeds a certain threshold. In that case, you could apply that...

I've searched and can't find an answer to this question. I could write the code myself to do it, but I don't want to reinvent the wheel. :) Since ZedGraph uses an IPointList and its indexer for internal data access, you can assign any kind of data structure to it and dynamically change the data that ZedGraph receives when it calls the indexer. It's a smart architecture, and naturally, it would be feasible to implement a Level-of-Detail system using a custom IPointList where the number of points is...
