Editable graphs?

[sapiogenesis]

This might be a wild question, but is ChartGPU suitable for implementing an editable graph? If yes, where should I dig if I wanted to tackle this?

Think something where you can draw data points with a mouse and/or clicking to add and move specific points around. The use case is more of a multimedia application rather than data visualization, but surprisingly in other aspects this library seems like a great fit for the particular widget I’m working on (ability to show multiple lines, smooth zooming, performance, all come in very handy).

Are changes to DataStore observed/automatically reflected? I can see that DataStore interface supports removeSeries() and appendSeries(), but they seem to operate on the entire series.

From a brief look, I suppose the steps are like:

• Implement requisite mouse interactions
• Wire any resulting changes to update the external data store and call respective DataStore update methods
• If remove/append the entire series is too slow for paint-style editing, extend DataStore interface to support per-point changes and somehow supply that DataStore implementation to the rest of the library
