(edited by Scott): This issue will track creating a financial charting demo with interactive chart functionality. It will remain a work in progress, but the list below will evolve to include new ideas as they are had and track implementation progress.

(edited by Scott): This issue will track adding an easier way to create financial charts without gaps (traditionally achieved using sequential mode) having a horizontal axis that displays dates and times

Feature Ideas

• Customizable bin times (e.g., 5 seconds, 1 hour, 1 day, etc.)
• Improved/simplified way to manage horizontal (DateTime) tick labels
• Dotted lines mark the candle nearest the mouse with snapping
• Option for zooming to automatically set vertical scale to fit the visible price range
• Improved management of linked multi-plot windows with price action on top and volume (or other metrics) on bottom
• Price histogram on vertical axis, presumably placed on the right side of the plot
• Drag-and-drop manipulation of technical indicators:
  • Trend line (segment, ray, extended)
  • Flat line (horizontal or vertical, ray or line)
  • Cross line
  • Automatic regression line given a time range
  • Parallelogram (is there a better name for this?) to highlight a channel of price movement
  • Triangular pattern
  • Multi-point lines like bat patterns
  • Fibonacci levels
