  1. Incomplete display in Curve mode

    in Desktop

    Posted

    Hi,

    I am having some display issue when rendering a chart in curve mode: The line isn't painted in some cases. It seems the scale of the Y-axis is not well adjusted to draw the inferior part of the line.

    Here is a simplified example that shows my problem:

    import java.awt.Dimension;

    import javax.swing.JFrame;

    import com.softwarefx.chartfx.desktop.Chart;
    import com.softwarefx.chartfx.desktop.Gallery;

    public class Example {

      public static void main(String[] args) {
      Chart c = new Chart();
      double vals[] = { 0, 0, 0, 0, 0, 134.5, 269, 404 };
      c.getData().setPoints(vals.length);
      for(int i = 0; i < vals.length; i++) {
      c.getData().set(0, i, vals);
      }
      c.getData().setSeries(1);
      c.setGallery(Gallery.CURVE);

      JFrame frame = new JFrame();
      frame.getContentPane().add©;
      frame.setSize(new Dimension(800, 600));
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setVisible(true);
      }
    }

    In this example, the line between points 4 and 5 is not drawn on screen since inferior to the minimum (although the y-axis is left to adjust according to values).

    Is there a way to make sure the curve line is always completely displayed on screen without having to force the minimum (since my values change dynamically)?

    Thanks for your help,

  2. Pyramid and zero values

    in Desktop

    Posted

    Hi,

     I am trying to display a Pyramid chart with last point value set to zero, however no chart is appearing. Anyone knows if I am missing something or if this is a bug?

     A simplified testcase to reproduce is:

    public static void main(String[] args) {
      Chart cc = new Chart();
      cc.setGallery(Gallery.PYRAMID);

      cc.getData().setSeries(1);
      cc.getData().setPoints(2);

      cc.getData().set(0, 0, 10);
      cc.getData().set(0, 1, 0); //If we change this value, the chart is displayed

      JFrame f = new JFrame();
      f.getContentPane().add(cc);
      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      f.pack();
      f.setVisible(true);
      }

    Note that the same chart displayed in Pie for example is visible.

    Thanks,

  3. Drawing 1 line per serie even if it has NULL values

    in Desktop

    Posted

     Hi,Is there a way or a workaround to display a chart line with only one continuous line per serie even if the serie doesn't have a certain value (one of the points has a NULL value)? For example, I have 2 series with the following values:Point Serie1 Serie20         0     01   2     32       4         63      6 NO VALUE4       8     125         10       15This is rendering 3 lines: one for serie1 and 2 discontinous lines for serie2. Can we join these 2 lines?Thanks,Shady

  6. Problem with setCustomFormat

    in Desktop

    Posted

    Hi,

    I am having a problem with the setCustomFormat method found in ValueFormat. In fact I tried the pattern given in the doc: "For example, you can use the format string "##0,," to represent 100 million as 100. Numbers smaller than 1 million are displayed as 0", however it is generating an error. Could someone please tell me what I am doing wrong?

    Here is the code I am testing:

    public static void main(String[] args) {   com.softwarefx.chartfx.desktop.Chart chart1 = new com.softwarefx.chartfx.desktop.Chart();   chart1.getToolBar().setVisible(true);   chart1.getAxisY().getLabelsFormat().setCustomFormat("##0,,");   for(int x = 0; x < 10; x++) {   chart1.getData().set(0, x, x * 1000000);   }   JFrame f = new JFrame();   f.getContentPane().add(chart1);   f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);   f.setSize(new Dimension(1500, 1000));   f.setVisible(true);   }

     And here is the error I am getting:

     Exception in thread "main" java.lang.IllegalArgumentException: Multiple decimal separators in pattern "##0,,"   at java.text.DecimalFormat.applyPattern(DecimalFormat.java:2520)   at java.text.DecimalFormat.applyLocalizedPattern(DecimalFormat.java:2312)   at com.softwarefx.sfxnet.System.Double.b(SourceFile:162)   at com.softwarefx.chartfx.desktop.internal.ValueFormat.a(SourceFile:278)   at com.softwarefx.chartfx.desktop.internal.ValueFormat.v(SourceFile:352)   at com.softwarefx.chartfx.desktop.internal.Axis.a(SourceFile:2014)   at com.softwarefx.chartfx.desktop.internal.Axis.a(SourceFile:2029)   at com.softwarefx.chartfx.desktop.internal.Axis.a(SourceFile:1995)   at com.softwarefx.chartfx.desktop.internal.Axis.a(SourceFile:2191)   at com.softwarefx.chartfx.desktop.internal.Axis.a(SourceFile:1967)   at com.softwarefx.chartfx.desktop.internal.Axis.a(SourceFile:1945)   at com.softwarefx.chartfx.desktop.internal.AxisCollection.a(SourceFile:54)   at com.softwarefx.chartfx.desktop.internal.Pane.a(SourceFile:287)   at com.softwarefx.chartfx.desktop.internal.PaneCollection.a(SourceFile:94)   at com.softwarefx.chartfx.desktop.internal.ScaleInfo.g(SourceFile:674)   at com.softwarefx.chartfx.desktop.internal.ScaleInfo.a(SourceFile:793)   at com.softwarefx.chartfx.desktop.internal.Chart.a(SourceFile:3427)   at com.softwarefx.chartfx.desktop.internal.u.a(SourceFile:793)   at com.softwarefx.chartfx.desktop.internal.u.a(SourceFile:438)   at com.softwarefx.chartfx.desktop.internal.Internal.DockableFrameCore.a(SourceFile:211)   at com.softwarefx.chartfx.desktop.internal.Internal.DockableFrameCore.a(SourceFile:141)   at com.softwarefx.chartfx.desktop.internal.Chart.e(SourceFile:4387)   at com.softwarefx.chartfx.desktop.internal.Chart.l(SourceFile:4213)   at com.softwarefx.sfxnet.internal.df$h.propertyChange(SourceFile:1217)   at com.softwarefx.chartfx.desktop.Chart.setVisible(SourceFile:2052)   at com.softwarefx.chartfx.desktop.Chart.doLayout(SourceFile:2071)   at java.awt.Container.validateTree(Container.java:1519)   at java.awt.Container.validateTree(Container.java:1526)   at java.awt.Container.validateTree(Container.java:1526)   at java.awt.Container.validateTree(Container.java:1526)   at java.awt.Container.validateTree(Container.java:1526)   at java.awt.Container.validate(Container.java:1491)   at java.awt.Window.show(Window.java:825)   at java.awt.Component.show(Component.java:1422)   at java.awt.Component.setVisible(Component.java:1375)   at java.awt.Window.setVisible(Window.java:806)

  7. Adding items to the toolbar

    in Desktop

    Posted

     Hi,

    I noticed  that we can add user-defined commands to the toolbar, however it seems that commands only support images. Is there a way to add comboboxes to this toolbar? In fact I need something similar to the gallery choices where the user can choose between certain values.

    Thanks for your help

  11. Resizing the charts

    in Desktop

    Posted

    Hi

    I am rendering a chart with the legendBox and the dataGrid both enabled. The problem is that when I resize the chart to a small dimension where not all of these components (chart, legendBox and dataGrid) can fit, the legendBox seems to have the priority over the chart: In fact, it stays visible while the chart becomes invisible. How can I give the chart a higher priority over the legendBox so that I always keep my chart visible?

    Thanks for your help

  14. Determining button on mouse click

    in Desktop

    Posted

    Hi,

    I was testing the Chart Fx 7 for java and tried to add a mouse click listener to my chart. However, I discovered that the HitTestEvent doesn't support the Right/Left mouse clicks. In fact, I can't find the equivalent of the getButton() found in java.awt.MouseEvent. Am I missing something or isn't it possible to distinguish a right click from a left click in the charts?

    Can anyone help?

    Thanks
