Close chart window without quitting repl

I am trying to use XChart in the scala repl, and every time I close the chart window, the repl is terminated.

For example:

import org.knowm.xchart.{SwingWrapper, QuickChart}

object UseXchart {
  def main(args: Array[String]) {
    val xData = Array(0.0, 1, 2)
    val yData = Array(2.0, 1, 0)
    val chart = QuickChart.getChart("title", "x", "y", "function", xData, yData)
    val swingChart: SwingWrapper = new SwingWrapper(chart))
    swingChart.displayChart()
  }
}

Is there a workaround? Thanks!

The reason appears to be that SwingWrapper does setDefaultCloseOperation(EXIT_ON_CLOSE) on its JFrame, which is returned by displayChart(). Something like this might work in Java (don’t know about Scala):

swingChart.displayChart().setDefaultCloseOperation(WindowConstants.HIDE_ON_CLOSE)

This worked for me: new SwingWrapper(pieChart).displayChart().setDefaultCloseOperation(WindowConstants.HIDE_ON_CLOSE);
