c3js Uncaught ReferenceError: chart is not defined

[Joveice]

So I have a few charts on my page and I'm trying to update them using the flow function

 

http://c3js.org/samples/api_flow.html

 

but I get Uncaught ReferenceError: chart is not defined

 

My code

 

chart.flow({
	bindto: '#test',
        columns: [
            ['data1', 230, 300, 330],
            ['data2', 190, 230, 200],
            ['data3', 90, 130, 180],
        ],
        duration: 1500
    });

What's wrong?

Simply said, the variable chart has not been defined! So you call flow on undefined.

You are just referring the variable chart, but it has never been declared or anything! I am not common with the library you use, but check their documentation! 

/* Maybe it will be somthing like this */
var chart = new ChartJS({
    key:value
});
