Milestone link with all the fixed/closed issues

• Add high level arg for base layer style to all mapbox charts

• Add ShowXAxisRangeSlider argument for Chart.OHLC and Chart.Candlestick

• Add multicategory data support for 2D traces

• Add high level camera projection args to all 3D chart apis

• Add missing Config params

• Refactor DisplayOptions - An object to control the way Charts are displayed in generated HTML files:

  • Add various functions to manipulate DisplayOptions, Refactor DisplayOptions as DynamicObj (again)
  • Add PlotlyJSReference type and logic to handle various ways of referencing plotly.js in HTML output:
    • Full: Include the full plotly.js source code. The currently supported plotly.js version is now included as embedded resource in the package. HTML files using this option are self-contained and can be used offline.
    • CDN: The default. uses a script tag in the head of the generated HTML to load plotly.js from a CDN.
    • Require: Use requirejs to load plotly. This option is now used in Plotly.NET.Interactive. Unnecessary usage of require.js is now removed from all other options but this.
    • NoReference: Don't include any plotly.js reference. Useful if you want to embed the output into another page that already references plotly.

• Use Giraffe.ViewEngine as html dsl

    • Add marker.cornerradius attribute to treemap trace
  • v2.16:
    • Add bounds to mapbox subplots
    • Add clustering options to scattermapbox
  • v2.15:
    • Add entrywidth and entrywidthmode to legend
    • Add minreducedwidth and minreducedheight to layout for increasing control over automargin
    • Add two new arrow marker symbols

    • Add selections, newselection and activeselection layout attributes to have persistent and editable selections over cartesian subplots
  • v2.12:
    • Implement various options to position and style minor ticks and grid lines on cartesian axis types
    • add griddash axis property to cartesian, polar, smith, ternary and geo subplots and add griddash and minorgriddash to carpet trace
  • v2.10:
    • Add support to use version 3 of MathJax and add typesetMath attribute to config
    • Add fill pattern to scatter and derived traces / chart APIs
  • v2.9:
    • add ticklabelstep attribute to axes and colorbars
  • v2.8:
    • add horizontal color bar options

Minor fixes for Object abstractions:

• Use correct Optional Parameter Attributes everywhere. This affects object abstractions for the following objects, but should be backwards compatible:
  • Annotation
  • LayoutImage
  • Pattern
  • TableCells
• FontSelectionStyle.init now correctly returns a FontSelectionStyle instead of unit

This release adopts strong assembly naming. This might cause backwards incompatibility and therefore results in an early major version increase. For more insights why we do this, check out the conversation on this issue
