API
The API consists of a primary draw method which accepts a configuration object, helper methods, and several microlibs.
Example
var // Container div: container = document // First data series: d1 = 0 3 4 8 8 5 9 13 // Second data series: d2 = // A couple flotr configuration options: options = xaxis: minorTickFreq: 4 grid: minorVerticalLines: true i graph; // Generated second data set: for i = 0; i < 14; i += 05 d2; // Draw the graph: graph = Flotr;
Microlibs
Extending
Flotr may be extended by adding new plugins and graph types.
Graph Types
Graph types define how a particular chart is rendered. Examples include line, bar, pie.
Existing graph types are found in js/types/
.
Plugins
Plugins extend the core of flotr with new functionality. They can add interactions, new decorations, etc. Examples include titles, labels and selection.
The plugins included are found in js/plugins/
.
Development
This project uses smoosh to build and jasmine
with js-imagediff to test. Tests may be executed by
jasmine-headless-webkit with
cd spec; jasmine-headless-webkit -j jasmine.yml -c
or by a browser by navigating to
flotr2/spec/SpecRunner.html
