XY graph support for segmented /conditional interpolation based on delta-x thresholds

Status: New
Another modernization feature (not on this comprehensive list already...) that would be nice to see in XY graphs:
 
We currently have to select an interpolation method per plot. Instead I would like to be able to say that if the next sample is less than a given delta apart from the previous it should draw a diagonal between the points, but if the delta is larger (due to deadband filtering e.g.) it should draw the previous sample value as a flat line until the new sample...
 
This could be added as an option in the manual selection method that visually showed a mix and had a name like dynamic or conditional (none of the options currently have a descriptive name or tip strip by the way so that is an idea as well; with an enum input for the property...). If conditional was chosen it could pop up a dialog asking for a definition of the condition. Similarily this would have to be a new interpolation option and an input of a threshold or list of such to set up the conditions. Just having two methods with a threshold would normally suffice...

Yes, we can off course achieve this today by doing the interpolation prior to feeding the data to the graph, but building this into the graph will simplify and seriously optimize the process.
