Another way to do this might be to make the dygraph object `then`able: ```js g = new Dygraph(div, 'path/to/non-existent.csv'); g.then(() => console.log('success!')) .catch(e => console.error(e)); ```

Does the "synchronize" demo show what you're looking for? There's a "selection" toggle. http://dygraphs.com/tests/synchronize.html

I'd imagined something like: ``` javascript { selectMode: 'closest-x' } ``` vs. ``` javascript { selectMode: 'euclidean' } ```

Alternatively, you could imagine making this a callback and having named functions for presets: ``` javascript { selectMode: Dygraph.findClosestByX } ``` ``` javascript { selectMode: Dygraph.findClosestByEuclidean } ``` I'd be...
