如何以编程方式从Jmeter生成响应时间图

我有以下java代码来运行JMeter .

import org.apache.jmeter.control.LoopController;
import org.apache.jmeter.engine.StandardJMeterEngine;
import org.apache.jmeter.protocol.http.sampler.HTTPSampler;
import org.apache.jmeter.testelement.TestElement;
import org.apache.jmeter.testelement.TestPlan;
import org.apache.jmeter.threads.SetupThreadGroup;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;

public class HCTGameDay {

public static void main(String[] args){
    // Engine
    StandardJMeterEngine jm = new StandardJMeterEngine();
    // jmeter.properties
    JMeterUtils.loadJMeterProperties("/Users/rokumar/Desktop/jmeter.properties");

    HashTree hashTree = new HashTree();     

    // HTTP Sampler
    HTTPSampler httpSampler = new HTTPSampler();
    httpSampler.setDomain("www.linkedin.com");
    httpSampler.setPort(80);
    httpSampler.setPath("/");
    httpSampler.setMethod("GET");

    // Loop Controller
    TestElement loopCtrl = new LoopController();
    ((LoopController)loopCtrl).setLoops(1);
    ((LoopController)loopCtrl).addTestElement(httpSampler);
    ((LoopController)loopCtrl).setFirst(true);

    // Thread Group
    SetupThreadGroup threadGroup = new SetupThreadGroup();
    threadGroup.setNumThreads(1);
    threadGroup.setRampUp(1);
    threadGroup.setSamplerController((LoopController)loopCtrl);

    // Test plan
    TestPlan testPlan = new TestPlan("HCT TEST PLAN");

    hashTree.add("testPlan", testPlan);
    hashTree.add("loopCtrl", loopCtrl);
    hashTree.add("threadGroup", threadGroup);
    hashTree.add("httpSampler", httpSampler);       

    jm.configure(hashTree);

    jm.run();
    }
}

我在控制台输出中没有得到任何结果 . 存储的响应时间等在哪里，如何以编程方式绘制响应时间，连接数，用户数的图表 .

    在 jm.configure(hashTree) 行之前添加以下代码

    //add Summarizer output to get test progress in stdout like:
// summary =      2 in   1.3s =    1.5/s Avg:   631 Min:   290 Max:   973 Err:     0 (0.00%)
Summariser summer = null;
String summariserName = JMeterUtils.getPropDefault("summariser.name", "summary");
if (summariserName.length() > 0) {
summer = new Summariser(summariserName);
}


// Store execution results into a .jtl file
String logFile = jmeterHome + System.getProperty("line.separator") + "example.jtl";
ResultCollector logger = new ResultCollector(summer);
logger.setFilename(logFile);
testPlanTree.add(hashTree.getArray()[0], logger);

    它将在JMeter安装的/ bin文件夹中生成 example.jtl 文件，这是适用于分析，图形生成等的常用JMeter结果文件 .
