$.jqplot.OHLCRenderer

jqPlot Plugin to draw Open Hi Low Close, Candlestick and Hi Low Close charts.

To use this plugin, include the renderer js file in your source:

<script type="text/javascript" src="plugins/jqplot.ohlcRenderer.js"></script>

You will most likely want to use a date axis renderer for the x axis also, so include the date axis render js file also:

<script type="text/javascript" src="plugins/jqplot.dateAxisRenderer.js"></script>

Then you set the renderer in the series options on your plot

series: [{renderer:$.jqplot.OHLCRenderer}]

For OHLC and candlestick charts, data should be specified like so:

dat = [['07/06/2009',138.7,139.68,135.18,135.4], ['06/29/2009',143.46,144.66,139.79,140.02], ...]

If the data array has only 4 values per point instead of 5, the renderer will create a Hi Low Close chart instead. In that case, data should be supplied like:

dat = [['07/06/2009',139.68,135.18,135.4], ['06/29/2009',144.66,139.79,140.02], ...]

To generate a candlestick chart instead of an OHLC chart, set the “candlestick” option to true:

series: [{renderer:$.jqplot.OHLCRenderer, rendererOptions:{candleStick:true}}],

candleStick

this.candleStick = false

true to render chart as candleStick. Must have an open price, cannot be a hlc chart.

this.tickLength = 'auto'

length of the line in pixels indicating open and close price. Default will auto calculate based on plot width and number of points displayed.

bodyWidth

this.bodyWidth = 'auto'

width of the candlestick body in pixels. Default will auto calculate based on plot width and number of candlesticks displayed.

openColor

this.openColor = null

color of the open price tick mark. Default is series color.

closeColor

this.closeColor = null

color of the close price tick mark. Default is series color.

wickColor

this.wickColor = null

color of the hi-lo line thorugh the candlestick body. Default is the series color.

fillUpBody

this.fillUpBody = false

true to render an “up” day (close price greater than open price) with a filled candlestick body.

fillDownBody

this.fillDownBody = true

true to render a “down” day (close price lower than open price) with a filled candlestick body.

upBodyColor

this.upBodyColor = null

downBodyColor

this.downBodyColor = null

Color of candlestick body on a “down” day. Default is series color.

hlc

this.hlc = false

true if is a hi-low-close chart (no open price). This is determined automatically from the series data.

lineWidth

this.lineWidth = 1.5
