What are symbols in a JavaFX line chart. How to disable them?

Inline chart the data values have represented a series of points connected by a line. In JavaFX, you can create a line chart by instantiating the javafx.scene.chart.LineChart class.

By default,

  • A JavaFX Line chart contains symbols pointing out the values in the series along the x-axis. Typically, these are small circles.

  • The X-Axis on the bottom in the plot.

  • Y-Axis on the left.

Disabling the symbols

The LineChart class has a property named createSymbols (boolean), which specifies whether to create symbols for data items in the chart. You can set values to this method using the setCreateSymbols() method.

To remove symbols from a line chart you need to invoke this method by passing the boolean value false as an argument to this method.
