## [Matplotlib-users] Interpolation between points during plot()

 [Matplotlib-users] Interpolation between points during plot() From: T J - 2010-02-13 03:05:15 ```Hi, When plotting, plot(x, y, marker="-") and its similar markers, what functionality in MPL is responsible for interpolating between the points? My naive guess is that interpolation is done in "display" coordinates since everything looks nice even when zooming in. I inquire because I'd like to make interpolation between two points follow some other path between the two points. In other words, I'd like to make a plot structure which will follow a different type of geodesic. Any tips or pointers in the right direction would be greatly appreciated. Thanks! ```

 Re: [Matplotlib-users] Interpolation between points during plot() From: Michael Droettboom - 2010-02-22 15:51:22 ```The drawing between the points is done using the regular "line drawing" commands of the backend. So there isn't really any low-level control over how the line between points is drawn. As a workaround, however, you can interpolate the data yourself and just pass more points to matplotlib. You may also be interested in this document if you're implementing new geodesics (though it doesn't solve the interpolation problem you describe): http://matplotlib.sourceforge.net/devel/add_new_projection.html Mike T J wrote: > Hi, > > When plotting, > > plot(x, y, marker="-") > > and its similar markers, what functionality in MPL is responsible for > interpolating between the points?
