v1.2.3

Improvements, fixes

• fixed a rounding issue regarding the upper interval boundary value of the lowest class, which came up when classRounding after classifying into a low number of target classes
• replaced all debug-related log messages with console.debug(), instead of the more intrusive overwriting of the global console.log function

From now on, if you encounter bugs, please include the verbose console output in your issue report (enable Verbose level/logging in your browser console to show debug messages)

v1.2.2

New features

• Legend: class feature counts
  • legendTemplate: new placeholder option {count} for including feature count in row of a given class interval. For example:

Legend row template example with {count} placeholder
Highest: {low}+ [{count}]	730000+ [2]
Middle: {low} – {high} [{count}]	350000 - 730000 [9]
Middle: {low} – {high} [{count}]	120000 - 350000 [16]
Lowest: < {high} [{count}]	< 120000 [23]
Nodata: No data [{count}]	No data [3]

Improvements, fixes

• reworked the main classes array as an array of objects (boundary value is accessible through classes[n].value)
• to aid feature counting, value evaluators now add up the number of found features for a given class, stored in the classes array (classes[n].featureCount property). Nodata/null features also get counted, stored in the classes.nodataFeatureCount property
• modified classRounding, unitModifier, middlePointValue, classification and color-generation logic to support classes as objects, instead of a plain array of numbers
• fixed the ignoring of nodata legend row template in some cases
• fixed some legend rows still not having css class legendDataRow
• css class legendDataRow: added a right margin of 4px
• updated examples (combined.html and points_s.html: feature counts are included in legend template to showcase feature; polygons.html: minor tweak for legend title)
• updated documentation
• updated main screenshot

v1.2

New features

• Null/nodata feature handling logic

  • new option noDataColor: fill color to use for features with null/nodata attribute values. In polygon, point-color and line-color modes. (default: '#606060'). Also appears in legend as a separate class/category. Currently, null/nodata features are not assigned a distinctive symbol when in point-size and line-width modes.
  • new option noDataIgnore: if true, features with null attribute values are not shown on the map. This also means the legend will not have a nodata classs (default: false)
  • new option nodata in legendTemplate: you can now customize the nodata text in Legend

Improvements

• modified classification code to filter out null attribute values when generating classes
• more thorough check for non-existing attribute field vs. null as attribute value (with more concise error messages)
• legend data rows (symbol + key) now have a css class (legendDataRow), set in leaflet-dataclassification.css, resulting in a cleaner legend-generation code
• updated documentation
