Ignore points with extreme coordinates when determining plotting area #3

Open Schnark opened 7 years ago

Schnark commented 7 years ago

Currently, the plotting area is set to include all given points. This is a bit problematic when there are points with extreme coordinates, e.g. when you want to plot the function 1/x. It would be nice if the library would detect such points (some methods are listed in https://en.wikipedia.org/wiki/Outlier#Detection) and ignore them when determining the plotting area and when plotting points/lines.

The library itself is meant to plot the points given, and it would not be appropriate to have this library making decisions about which points to include or not. I can see two possible solutions: 1) Add a layer that does the analysis you are talking about. Pro - you get the desired behavior, con, the library renders by interpolation, so removing points arbitrarily could change the shape of the plot. 2) Add a control to define the plot region, both in x and y. I'll consider the latter as a feature request linked to the pan/zoom option.
