Conditionally Change Formats

Building on the Quick Start example, you can change the format of the candlestick for each day based on its values using the candlestickFormatter option.

In the <head> section of your HTML file, replace the script that includes the document ready function with this one, which uses the candlestickFormatter option.

No changes are necessary in the <body> section of your HTML file. The basic <div> tag is sufficient to create the widget.
Save your HTML file and open it in a browser. The widget appears like the one in the live widget below, with the days on which the open value is higher than the close value rendered in red.
