React component for NVD3 re-usable charting library
## Requirements
* NVD3
* D3
* ReactJS
## Quick start
```javascript
BarChart
```
## How do I add this to my project?
* Using bower and running `bower install react-nvd3`
* Using npm and running `npm install react-nvd3`
* Downloading it manually by clicking [here to download minified version](https://raw.githubusercontent.com/NuCivic/react-nvd3/master/dist/react-nvd3.min.js)
## How to use
```javascript
```
#### 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:
```javascript
function getX(d){
return d.label;
}
React.render(
,
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
```javascript
React.render(
,
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.
```javascript
React.render(
,
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:
```javascript
React.render(
,
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:
```javascript
React.render(
,
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:
```javascript
var chart = {
id:'barChart',
type:'discreteBarChart',
datum: datum,
x: 'label',
y: 'value'
};
React.render(
React.createElement('NVD3Chart', chart),
document.getElementById('barChart')
);
```
Or this:
```javascript
// I've included jQuery here because I want to simplify the code, but it's not required.
$.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:
```javascript
var context = {
getColor: function(i){
var colors = d3.scale.category20().range().slice(10);
return colors[Math.floor(Math.random() * colors.length)];
}
};
ReactDOM.render(
,
document.getElementById('barChart')
);
```
