        <h1>noZoomFlagChange Operation</h1>
        <p>
            By default, when the <code>dateWindow</code> or <code>updateOptions</code>
            of a chart is changed programmatically by a call to <code>updateOptions</code>
            the zoomed flags (<code>isZoomed</code>) are changed. This is the same
            as manually zooming in using the mouse.
        </p>
        <p>
            Sometimes it may be desirable to change the display of the chart by
            manipulating the <code>dateWindow</code> and <code>valueRange</code>
            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.
        </p>
        <p>
            In this case <code>noZoomFlagChange</code> may be specified along with
            either the <code>dateWindow</code> or <code>valueRange</code> values to
            <code>updateOptions</code> and the zoomed flags will remain unaffected.
        </p>
        <p>
            The chart below may be manipulated to change the <code>updateOptions</code>
            using the Max and Min Y axis buttons and the <code>dateWindow</code>
            by using the Max and Min X axis buttons.
        </p>
        <p>
            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.
        </p>
        <p><input id="noZoomFlagChange" type="checkbox" checked=true />Do not change zoom flags (<code>noZoomFlagChange</code>)</p>
