By default, when the dateWindow or updateOptions
of a chart is changed programmatically by a call to updateOptions
the zoomed flags (isZoomed) are changed. This is the same
as manually zooming in using the mouse.
Sometimes it may be desirable to change the display of the chart by
manipulating the dateWindow and valueRange
options but without changing the zoomed flags, for example where manual
zooming is still required but where it is also desired that the zoomed
flags drive display elements, but only for manual zooming.
In this case isZoomedIgnoreProgrammaticZoom may be specified along with
either the dateWindow or valueRange values to
updateOptions and the zoomed flags will remain unaffected.
The chart below may be manipulated to change the updateOptions
using the Max and Min Y axis buttons and the dateWindow
by using the Max and Min X axis buttons.
Toggle the check box below to determine the difference in operation of the zoom flags when the date and value windows of the chart are changed using the arrows underneath.
Do not change zoom flags (isZoomedIgnoreProgrammaticZoom)
