java - Choose the series of data that you want to display -

i have plot multiple series of data:

i want able pick series want display. example, 0° , 20° ones. there simple way manipulating chart without using jcheckbox? want able this, example, clicking on legend of series.

as shown here, jcheckbox more flexible, clicking directly on chart may more convenient. example below adds chartmouselistener makes series invisible when clicking on either xyitementity in series or legenditementity. of course, once series invisible, cannot clicked on again; you'll need way restore visibility. among alternatives, first illustrated below:

• restore visibility of series when clicking elsewhere on chart.

• combine approach cited above, toggling jcheckbox accordingly in implementation of chartmouseclicked().

• loop through series in button handler, restoring visibility of each.
