... I have a problem.I use Candle Stick sample from demo named 'CandlestickChartDemo1'.
For easy understand of the question, I modify this sample's dataset and make it more like a real world trading mode. (which will not have any value in Saturday,Sunday and Public Holiday).
Here is my code:
Code: Select all
package demo;

public class JCandlestickChartDemo2 extends ApplicationFrame
{
public JCandlestickChartDemo2(String s)
{
super(s);
OHLCDataset ohlcdataset = createDataset();
JFreeChart jfreechart = createChart(ohlcdataset);
jfreechart.getXYPlot().setOrientation(PlotOrientation.VERTICAL);
ChartPanel chartpanel = new ChartPanel(jfreechart);
chartpanel.setPreferredSize(new Dimension(500, 270));
setContentPane(chartpanel);
}
private static JFreeChart createChart(OHLCDataset ohlcdataset)
{
JFreeChart jfreechart = ChartFactory.createCandlestickChart("Candlestick Demo", "Time", "Value", ohlcdataset, true);
return jfreechart;
}

}
}
My question as follow:
1) I hope I can trim out the non-market day(saturday,sunday and non market day(public holiday). Because my historical feed data do not include non-market day. So when I pass array into new DefaultHighLowDataset("Historical Data", aDate, aHi, aLow, aOpen, aClose, aVol); , the non-market day will also shown in the chart which I want to trim it out.
Summarize of question: Actually I hope I can let the x-axis trim out all null value(non-market day,I didn't pass any value on that Date) and combine the chart as diagram below:(no space/null val for non-market day)
Sorry, my english not very fluent, hope experts don't mind.
Thanks for spending valuable time to help me.
