1.0

[milliams]

This is an overview issue to track all the feature we want before 1.0:

• [ ] lots of plot types
• [ ] legends
• [ ] output plots in may formats
  • [x] SVG
  • [x] ASCII
  • [ ] PNG
  • [ ] 3D format
• [ ] different projections
  • [x] normal 2D plot
  • [ ] 3D plot on a 2D page
  • [ ] map projections
• [ ] dual y-axes
• [ ] combined (e.g. scatter plus histogram) plots
• [ ] easy to get own data into plots
• [ ] extensible with new output formats and projects
• [ ] custom axis formatting
• [ ] custom styling

What about adding PNG to the list of output formats ? I actually don't know how some of the PNG crates work

What do you think about adding the image crate and extending the View trait with some "to_image" method?

Also annotations (text with pointers towards data points) would be a really nice feature!

I might be tempted to contribute in the future to add candle bar plotting available, but I notice the axis is defined with floats while plotting of time series requires some notion of time and duration.

3 questions:

• Is time series support something you plan to add soon? (so I do not start working on it to see it committed before I'm done...)

• Between introducing a Coordinate (and maybe an Interval too) trait and having multiple types (integer types, f32, f64, potentially chrono::NaiveTime, chrono::NaiveDate and chrono::NaiveDateTime (behind a feature gate) implement them to potentially get to an abstract Axis<Coordinate> or just using a UNIX timestamp turned into an f64 to represent time-series' coordinates, what would you prefer?

• Would it be risky for me to start working on those in a few weeks? (e.g. is there any big refactoring planned?)

Otherwise, I am really happy to see a decent-looking crate for plotting appearing. I was actually thinking of making my own soon (I am studying algorithmic trading) and I feel this will save me a lot of time.
