在使拨号图表获得不支持的图表类型时：拨号错误

Question

我正在尝试使用zk框架（JFreeChart）绘制拨号图表。请在下面找到代码：

chart1Dial.zul

<?page title="new page title" contentType="text/html;charset=UTF-8"?>
 <zk>
  <window title="new page title" border="normal">

   <hlayout spacing="10px" apply="org.zkoss.bind.BindComposer" 
      viewModel="@id('vm') @init('demo.chart.dial.DialChartVM')">
   <chart id="chartC" width="250" height="250" 
    paneColor="#ffffff" type="dial"
    model="@bind(vm.celsiusModel)" engine="@bind(vm.engine)"/>

   <!--     <chart id="chartF" width="250" height="250" 
    paneColor="#ffffff" type="dial" 
    model="@bind(vm.fahrenheitModel)"/> -->
    </hlayout>

    </window>
   </zk>

ChartData.Java ：

 package demo.chart.dial;

 import java.awt.Color;

 import org.zkoss.zul.DialModel;
 import org.zkoss.zul.DialModelScale;

 import demo.chart.ChartColors;

public class ChartData {

public static DialModel createCelsiusModel(){
    DialModel model = new DialModel();

    model.setFrameFgColor("#808080");
    model.setFrameBgAlpha(255);
    model.setFrameBgColor("#FFFFFF");
    model.setFrameBgColor1("#000000");
    model.setFrameBgColor2("#000000");

    model.setCapRadius(0.1);

    model.setGradientDirection("vertical");

    return model;
}

public static int toFahrenhit(int celsius){
    return Math.round(celsius * 9 / 5 + 32);
}

public static int toCelsius(int fahrenheit){
    return Math.round((fahrenheit - 32) * 5 / 9);
}
}

DialChartEngine.Java

   package demo.chart.dial;

  import org.jfree.chart.JFreeChart;
  import org.zkoss.zkex.zul.impl.JFreeChartEngine;
  import org.zkoss.zul.Chart;
  import org.zkoss.zul.DialModel;
  import org.zkoss.zul.DialModelScale;
  import java.awt.Color;

 import demo.chart.ChartColors;

 public class DialChartEngine extends JFreeChartEngine {

 private boolean explode = false;

 public boolean prepareJFreeChart(JFreeChart jfchart, Chart chart) {



    DialModel model = new DialModel();

    DialModelScale scale = model.newScale(-10.0, 60.0, 230, -280, 10.0, 4);


    //scale's configuration data
    scale.setValue(27);
    scale.setText("Celsius");
    scale.newRange(-10,  0, ChartColors.toHtmlColor(Color.getHSBColor(0.55f, 0.8f, 1)), 0.61, 0.603);
    scale.newRange(  0, 10, ChartColors.toHtmlColor(Color.getHSBColor(0.3f , 0.8f, 1)), 0.61, 0.603);
    scale.newRange( 10, 20, ChartColors.toHtmlColor(Color.getHSBColor(0.18f, 0.8f, 1)), 0.61, 0.603);
    scale.newRange( 20, 30, ChartColors.toHtmlColor(Color.getHSBColor(0.12f, 0.8f, 1)), 0.61, 0.603);
    scale.newRange( 30, 40, ChartColors.toHtmlColor(Color.getHSBColor(0.08f, 0.8f, 1)), 0.61, 0.603);
    scale.newRange( 40, 50, ChartColors.toHtmlColor(Color.getHSBColor(0.05f, 0.8f, 1)), 0.61, 0.603);
    scale.newRange( 50, 60, ChartColors.toHtmlColor(Color.getHSBColor(0.0f , 0.8f, 1)), 0.61, 0.603);
    scale.setTickColor("#FFFFFF");
    scale.setNeedleType("pin");
    scale.setNeedleColor("#FF0000");

    return true;

 }

 public void setExplode(boolean explode) {
        this.explode = explode;
    }
  }

DialChartVM.Java

package demo.chart.dial;

import org.zkoss.bind.annotation.BindingParam;
import org.zkoss.bind.annotation.GlobalCommand;
import org.zkoss.bind.annotation.Init;
import org.zkoss.zul.DialModel;



public class DialChartVM {

DialModel celsiusModel;

DialChartEngine engine;

public DialModel getCelsiusModel() {
    return celsiusModel;
}

/*public DialModel getFahrenheitModel() {
    return fahrenheitModel;
}*/

 public DialChartEngine getEngine() {
        return engine;
    }

@Init
public void init() {
    int celsius = 27;
    celsiusModel = ChartData.createCelsiusModel();

    engine = new DialChartEngine();
}

}

当我尝试执行以下代码时，我收到一条错误消息：

尚不支持的图表类型：拨打

以下是 错误 ：

请告诉我如何进一步处理。谢谢

我现在能够绘制拨号盘，因为我已经下载了所有zk-jar（版本8）

请在下面找到我的工作代码：

<强> chart1Dail.zul

    paneColor="#ffffff" type="dial"
    model="@bind(vm.celsiusModel)" />

</hlayout>

</window>

public class DialChartVM {

DialModel celsiusModel;

public DialModel getCelsiusModel() {
    return celsiusModel;
}


@Init
public void init() {
    int celsius = 50;
    celsiusModel = ChartData.createCelsiusModel(celsius);

}   

}

    DialModelScale scale = model.newScale(-10.0, 60.0, 230, -280, 10.0, 4);


    //scale's configuration data
    scale.setValue(value);
    scale.setText("Celsius");
    scale.newRange(-10,  0, ChartColors.toHtmlColor(Color.getHSBColor(0.55f, 0.8f, 1)), 0.61, 0.603);

    model.setCapRadius(0.1);

    model.setGradientDirection("vertical");

    return model;
}

public static int toFahrenhit(int celsius){
    return Math.round(celsius * 9 / 5 + 32);
}

public static int toCelsius(int fahrenheit){
    return Math.round((fahrenheit - 32) * 5 / 9);
}
}

我删除了 DialChartEngine.Java 文件。
