ZingChart Distributed Weighted Average Module

This module calculates the distributed weighted average of your plots.

Usage

1. Include the module in your page after the zingchart library
2. Include the module reference in the zingchart.render({}) method.

zingchart.render({
		id : 'myChart',
		data : myConfig,
		height: 400,
		width: '100%',
		modules: "dwa" // Include the dwa module!
});

Docs

There are a couple attributes you can define in your chart configuration for the dwa module.

1. dwa (object) - This object can be defined in the root of the chart configuration. Within this object you can define two properties visibleAtFirst and name.
   • visibleAtFirst (boolean) - If true this attribute will show the dwa plot when the graph loads. This is the default.
   • name (string) - If defined, this name will appear in the legend. The default text is "Weighted Average".
   • color (string) - If defined this will set the color of your dwa plot. Otherwise it will default to the standard library color for that plot.

dwa:{
            // 'dwa' module is loaded in the render method below.
            visibleAtFirst:true, // Default is true
            name: "Distributed Weighted Average", // Optional Name
            color: '#000' // Optional Color
        },

2. weight (Number) - If defined, it must be defined within each individual series object. The default weight is 1, in which case the weighted average is an even distribution amongst plots.

series : [
        {
            values: [35,42,67,89,25,34,67,85],
            weight: 0.4 // optional weight
        },
        {
            values: [74,71,89,34,26,73,21,56],
            weight: 0.6 // optional weight
        }
   ]
