chart.update() doesn't enable the navigator under certain conditions

[ransoing]

Expected behaviour

Calling chart.update() to toggle navigator.enabled should always work properly.

Actual behaviour

If a plot is initialized with both scrollbar.enabled and navigator.enabled set to false, then the navigator will not appear when chart.update( {navigator: {enabled:true}} ) is called.

If the plot is initialized with either scrollbar.enabled or navigator.enabled set to true, then it will work properly.

Live demo with steps to reproduce

Press the "Toggle Navigators" button. Note how the second plot does not show a navigator.

Hi,

Thank you for reporting about the bug.

Internalnote: Navigator is added only on beforeRender event and cannot be added through chart.update.

Internal note
It seems that options are not "updated" in update function. However when we edit it, it is still wrong.

Workaround:
Set options for navigator manually, fire event that adds navigator/scrollbar, redraw the chart to see the changes.
