body: <p>I'm writing a declarative jenkins pipeline and I'm facing problems with gatling reports:</p>

  <p>Mean response time trend is not correct, Is there a way to replace following cloud of dots by a curve ?</p>
  
  <p>Extracts from my Jenkinsfile:</p>
  
  <pre><code>stage('perf') {
    steps {
      bzt params: './taurus/scenario.yml', generatePerformanceTrend: false, printDebugOutput: true
      perfReport configType: 'PRT', graphType: 'PRT', ignoreFailedBuilds: true, modePerformancePerTestCase: true, modeThroughput: true, sourceDataFiles: 'results.xml'
      dir ("taurus/results") {
        gatlingArchive()
      }
    }
  }
  </code></pre>
  
  <p>Extract from my <em>scenario.yml</em>:</p>
  
  <pre><code>modules:
    gatling:
      path:      ./bin/gatling.sh
      java-opts: -Dgatling.core.directory.data=./data
  </code></pre>
  
  <p>In <em>scenario.yml</em>, I tried to set <code>gatling.core.outputDirectoryBaseName</code> :</p>
  
  <pre><code>java-opts: -Dgatling.core.directory.data=./data -Dgatling.core.outputDirectoryBaseName=./my_scenario
  </code></pre>
  
  <p>In this case it replace only <em>gatling</em> by <em>my_scenario</em>, but huge number is already present.</p>
