New Features

  • scalableyaxis plugin allows for users to drag scales Demo

  • Added "preview-state" object to series items to be able to override style displayed in the preview box. This only applies to bar, line and area charts. Demo

  • Added "connect-nulls" to series items (works currently only on line/area in fast mode) to draw lines through large breaks in data that are filled with null values Demo

  • Arrow tip removal through aspect: [0,0] Demo

  • New zoom variables emitted xzoomed : true || false yzoomed : true || false. Hiding and showing buttons on Zoom is now a breeze. Demo

Updated Features

  • placement option for radar value box placement: (in | over | out). Position can also be tweaked with offset-r attribute Demo

  • Added collapse:true to legend to force minimized initial state Demo

  • Added single-line: true attribute in crosshairX. Ised with exact: false it will show all plot labels but display only one crosshair line and scale label. Typical used when null values are present and multiple guides are showing up.

  • Added alt tags to image map for 508 compliance. Alt tag is empty and will pass the 508 compliance test telling screen readers it is decorative and not informational.

  • Image export APIs and routines now export preview window state (both SVG and CANVAS) Demo
