Overview

A candlestick chart that is rendered as an image using the Google Charts API.

A candlestick chart is used to show an opening and closing value overlaid on top of a total variance. Candlestick charts are often used to show stock value behavior. In this chart, items where the opening value is less than the closing value are drawn in green, and items where the opening value is more than the closing value are drawn in red. See the candlestick documentation in the Google Charts API for more information.

        var options = {};
        dataTable = google.visualization.arrayToDataTable([
