How do I add this to my project?
How to use
<NVD3Chart id="barChart" type="discreteBarChart" datum={datum} x="label" y="value"/>
Type (string):
Chart type you want to use. Posible values are:
- lineChart
- scatterChart
- stackedAreaChart
- discreteBarChart
- multiBarChart
- multiBarHorizontalChart
- linePlusBarChart
- cumulativeLineChart
- lineWithFocusChart
- pieChart
- bulletChart
- indentedTree
Datum (array|function):
A collection of data or a function that returns it.
x (string|function)
The key in the collection that should be used as x value or a function that returns it:
function getX(d){
return d.label;
}
React.render(
<NVD3Chart id="barChart" type="discreteBarChart" datum={datum} x={getX} y="value"/>,
document.getElementById('barChart')
);
y (string|function)
The key in the collection that should be used as y value or a function that returns it.
margin (object)
To set chart margins you should provide an object with the wanted margins. For example
React.render(
<NVD3Chart id="barChart" type="discreteBarChart" datum={datum} margin={{left:200}}/>,
document.getElementById('barChart')
);
Events
ready (function)
A function to be called right after the first transition ends. This event is triggered only once.
renderStart (function)
A function to be called each time the chart rendering starts.
renderEnd (function)
A function to be called each time the chart transition ends.
React.render(
<NVD3Chart
type="discreteBarChart"
datum={datum}
renderEnd={mycallbackEnd}
renderStart={mycallbackStart}
ready={mycallbackReady} />,
document.getElementById('barChart')
);
Available chart configurations
All the nvd3 configurations for each chart are available. For example if you are using the discreteBarChart then you could show values in this way:
React.render(
<NVD3Chart id="barChart" type="discreteBarChart" showValues="true" datum={datum} x="x" y="value"/>,
document.getElementById('barChart')
);
For more information about the available options you could check the nvd3 documentation http://nvd3.org/
NOTICE: An extensive documentation with examples is embeded in the repository https://github.com/novus/nvd3/blob/master/examples/documentation.html . If you want to check it just clone it and open that file.
Configure nested nvd3 components
If you need to configure nested nvd3 components you need to pass a nested object with the configurations to the property that match with the nested component.
Suppose you need to disable tooltips in your charts:
React.render(
<NVD3Chart tooltip={{enabled: true}} id="barChart" type="discreteBarChart" showValues="true" datum={datum} x="x" y="value"/>,
document.getElementById('barChart')
);
In this case we are passing the nested object to configure the tooltip. This is also applicable to axis components.
Do you want to load a chart from your database?
Since react allow you to use a plain javascript syntax to pass props then you could do this:
var chart = {
id:'barChart',
type:'discreteBarChart',
datum: datum,
x: 'label',
y: 'value'
};
React.render(
React.createElement('NVD3Chart', chart),
document.getElementById('barChart')
);
Or this:
$.getJSON('/mychartendpoint/1',function(chart){
React.render(
React.createElement('NVD3Chart', chart),
document.getElementById('barChart')
);
});
Ok, but what about axis formatters and other functions?
Formatters are functions and we don't want to stored them in a database. If you want to persist your chart state somewhere you need to have a plain json object.
Instead of persist your function implementations in your json you need to create a reference from the json object and pass those functions by context at the moment you instantiate the chart.
Suppose you have a function called getColor to assign the colors in your charts. In this case you'll need to create a context object with the getColor function implementation inside and pass the reference to the color property.
Function references have this format: {name:'functionNameInContext', type:'function'}
.
Let's see an example:
var context = {
getColor: function(i){
var colors = d3.scale.category20().range().slice(10);
return colors[Math.floor(Math.random() * colors.length)];
}
};
ReactDOM.render(
<NVD3Chart context={context} color={{name:'getColor', type:'function'}} type="discreteBarChart" datum={datum} x="label" y="value" />,
document.getElementById('barChart')
);

Source code is pretty straightforward. You can take a look at https://github.com/NuCivic/react-nvd3/blob/master/index.js.
