Re: CandleStick Charts, Changing the color of the high and low bars

[Hoa Hoang]

So I was able to change the color of the vertical bar to black by editing the series option.

series: {    0:{color: "Black"},

1: {type: "line"}, 

2: {type:"line"}}

However, this changes the colors for all the series, instead of just the ones I want.
Ideally, the falling numbers will have a red vertical high/low bar, 

and the rising numbers should have a green vertical bar.

Any ideas on how I can accomplish this?

I'm trying to customize the candlestick charts.
I want the rising candlesticks to be hollow and falling candlesticks to be red.
However, when I try to change the stroke and the fill, the horizontal bars representing the high and the low stay the default blue color.

I end up with this: http://imgur.com/NoAzr

Here's what my options look like.

var options = {

 candlestick: {hollowIsRising : true,

     risingColor: {stroke: "Green"},

     fallingColor : {color: "DarkRed",fill : "DarkRed", stroke: "DarkRed",strokeWidth: 1 }},

          title : 'Monthly Coffee Production by Country',

          vAxis: {title: "price"},

          hAxis: {title: "Month"},

          seriesType: "candlesticks",

          series: { 

1: {type: "line"}, 

2: {type:"line"}}

        };

The wicks of the candlestick are colored by the series color and not by the rising/falling state, and there is no way to force them to be colored by rising/falling state.  You could try using a DataView to separate out the rising and falling values into their own series and graphing them accordingly.  This would get you the colors you want, but your candles would be misaligned in the horizontal space (as each would have an empty spot where a candle from the other series would have been placed next to it).
