chart.setModel(getData.getXYModel());
chart.setWidth(width);
chart.setHeight(height);
chart.getSeries(0).setColor("red");
chart.getSeries(1).setColor("blue");
**chart.getSeries(2).setColor("green");**
Please check this example https://github.com/zkoss/zkchartsessentials/blob/master/src/main/java/org/zkoss/zkcharts/essentials/customizing/DraggablePointComposer.java
Thank for your quick response. I was able to turn on the correct series for draggable point. However, is there a way to enable/disable the draggable point features dynamically? I don't want it enable all the time. It gets in the way of normal chart interaction.

chart.addEventListener(Events.ON_CTRL_KEY , new EventListener() {
@Override
public void onEvent(Event event) throws Exception {
int keyCode = ((KeyEvent) event).getKeyCode();
System.out.println("Key coded: " + keyCode);
if (keyCode == 90){
System.out.println("Pressed Ctrl + z");
//enable drag and drop on Y axis.
chart.getSeries(2).getDragDrop().setDraggableY(true);
}else {
//disabl drag and drop on Y axis.
chart.getSeries(2).getDragDrop().setDraggableY(false);
}
}
});
Is there away to capture/display the new dragged y-axis values?
For example, when I dragged the original y-value from 100 to 150. The chart shows the correct value visually, but when I clicked on the newly dragged value, it was still the old value(100).
