I can't find how to modify the label of the y axis. For now I use a TimeSeries with the MINUTE class, and then insert the TimeSeries into a Dataset. It look like this : final TimeSeries s1 = new TimeSeries("Importation Time", Minute.class); s1.add(new Minute(dateFinal),concateHourAndMinuteToGetASingleValue); dataset.addSeries(s1); What I would like to do is to modify the display label, and put a String (05h20 for exemple) instead of the Double value. Any help would be much appreciated :) Thank you! You will need to set a FormatOverride on the axis . Here is an example for both a NumberAxis and

This question relates to a similar question I posted on here a few days ago... Here is the interface which will show where I am wanting the chart to appear: I am wanting to display the chart on the large JPanel on the right hand side. What the chart is meant to do is to compare a particular player's stats with their country's average and the overall average (with three bars). The chart (should) know which player to show the comparison by getting the player's name from the textbox (the one with "getPlayerName" already in it. As with my similar question mentioned earlier, I have created a class

I am using JFreeChart to plot two series of data (XYSeries) using a linechart. The complicating factor is that one of the data series has y-values that are typically much higher than the y-values of my second data series (let's say that the first series has y-values in the order of magnitude of millions, while the second series has y-values in the order of magnitude of hundreds). The existence of the high values in my first data set cause the range of the plot to be such that the y-values of my second data set are not comprehensible anymore. Adding a second y-axis to the plot, such that both

在前面之间加上下面这段代码即可。 //创建主题样式 StandardChartTheme standardChartTheme=new StandardChartTheme("CN"); //设置标题字体 standardChartTheme.setExtraLargeFont(new Font("隶书",Font.BOLD,20)); //设置图例的字体 standardChartTheme.setRegularFont(new Font("宋书",Font.PLAIN,15)); //设置轴向的字体 standardChartTheme.setLargeFont(new Font("宋书",Font.PLAIN,15)); //应用主题样式 ChartFactory.setChartTheme(standardChartTheme); 为了验证，先给出没有上面代码的一串代码： import java.awt.Font; import javax.swing.JPanel; import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import org.jfree.chart.axis.CategoryAxis; import

Currently, the PolarChart joins all the coordinates with lines creating a polygon. I just want it to plot each point with a dot and NOT join them together. Is this possible? I have tried using translateValueThetaRadiusToJava2D() and Graphics2D to draw circles but it's very clunky and contrived. Any suggestions welcome! So the DefaultPolarItemRenderer takes in all the polar points, converts the polar points to regular Java2D coordinates, makes a Polygon with those points and then draws it. Here's how I got it to draw dots instead of a polygon: public class MyDefaultPolarItemRenderer extends

I'm plotting a TimeTableXYDataset using a StackedXYBarRenderer . Unfortunately the colours of each series change on refresh. I know how to set colours using the setSeriesPaint method of the renderer, but that takes an integer series index as the argument. I create my datapoints using a string as the series name: ds.add(new SimpleTimePeriod(us.getDate(), new Date(us.getDate().getTime() + 1000*60)), us.getTotal(), us.getName())); How do I discover the mapping between series name and series index so I can call setSeriesPaint ? The easiest approach is to update a suitable Map as the data
