< a href = '#api' > 4. Use APIs< / a >
< / h3 >
< p > By using APIs, you can update the chart after it's been rendered. We will introduce some of APIs here. APIs can be called through the object returned from < span class = "code" > generate()< / span > .< / p >
< h4 > 1. Load Data< / h4 >
< p > By using < span class = "code" > load()< / span > API, you can load data and update the chart dynamically as follows:< / p >
< div class = 'sourcecode highlight' >
< pre > < code class = 'javascript' > // var chart = c3.generate({ ... });
 
 chart.load({
 columns: [
 ['data1', 300, 100, 250, 150, 300, 150, 500],
 ['data2', 100, 200, 150, 50, 100, 250]
 ]
 });
 < / code > < / pre >
< / div >
< p > If you push the button "Load" below, this code will run and the chart will be updated.< / p >
< button class = 'small' onclick = 'example4_1();' > Load< / button >
< div id = 'chart4_1' > < / div >
< br >
< h4 > 2. Unload Data< / h4 >
< p > By using < span class = "code" > unload()< / span > API, you can unload the data dynamically as follows:< / p >
< div class = 'sourcecode highlight' >
< pre > < code class = 'javascript' > // var chart = c3.generate({ ... });
 
 chart.unload({
 ids: ['data2', 'data3']
 });
 < / code > < / pre >
< / div >
< p > If you push the button "Unload" below, this code will run and the chart will be updated.< / p >
< button class = 'small' onclick = 'example4_2();' > Unload< / button >
< div id = 'chart4_2' > < / div >
< br >
< p > Please use < span class = "code" > unload< / span > param in < span class = "code" > load()< / span > API if load and unload need to run simultaneously. Please see < a href = "/samples/data_load.html" > this example< / a > .< / p >
< h4 > 3. Show/Hide Data< / h4 >
< p > By using < span class = "code" > show()< / span > and < span class = "code" > hide()< / span > API, you can show/hide the data dynamically as follows:< / p >
< div class = 'sourcecode highlight' >
< pre > < code class = 'javascript' > // var chart = c3.generate({ ... });
 
 chart.hide(['data2', 'data3']);
 chart.show(['data2', 'data3']);
 < / code > < / pre >
< / div >
< p > If you push the button "Show" and "Hide" below, this code will run and the chart will be updated.< / p >
< button class = 'small' onclick = 'example4_3_2();' > Hide< / button >
< button class = 'small' onclick = 'example4_3_1();' > Show< / button >
< div id = 'chart4_3' > < / div >
< br >
< p > The documentation about APIs is poor now, so please check the < a href = "https://github.com/c3js/c3/issues?state=open" > issues on github< / a > . There might be some hints about what you want to do. (We will add the document soon)< / p >
< / section >
< hr >
< section >
< h3 >
< a href = '#style' > 5. Customize Style< / a >
< / h3 >
< p > C3 give some classes for each element when generating. So, you can change the style of the elements by using those classes.< / p >
< h4 > 1. Line style< / h4 >
< p > The lines have < span class = "code" > c3-line-[id]< / span > class, so this class can be used to define the style in css as follows:< / p >
< div class = 'sourcecode highlight' >
< pre > < code class = 'css' > #chart .c3-line-data2 {
 stroke-width: 5px;
 }
 < / code > < / pre >
< / div >
< div id = 'chart5_1' > < / div >
< br >
< p > Please check the class for each element if you want to change the style. Web Inspector would be useful. (We will add the document for class definition soon)< / p >
< / section >
< hr >
< section >
< h3 >
< a href = '#more' > 6. And More..< / a >
< / h3 >
< p > Please check the < a href = "/examples.html" > examples< / a > and the < a href = "https://github.com/c3js/c3/issues?state=open" > issues< / a > on github for more information. Sorry for the poor documentation. We're working on now and please give me some time. Thank you.< / p >
