Google Charts - Basic Candlestick Chart


Advertisements

Following is an example of a basic candlestick chart. A candlestick chart is generally used to show an opening and closing value which are overlaid on top of a total variance. Candlestick charts are often used to show stocks value behavior. In this chart, filled boxes are drawn for items where the opening value is less than the closing value (a gain) and , and hollow boxes are drawn where the opening value of item is more than the closing value (a loss). We've already seen the configuration used to draw this chart in Google Charts Configuration Syntax chapter. So, let's see the complete example.

Configurations

We've used CandlestickChart class to show candlestick based chart.

var chart = new google.visualization.CandlestickChart
