+ <h3>Programmatic Zoom</h3>
+ <p>
+ When a chart is programmatically zoomed by updating either the <code>dateWindow</code>
+ or <code>valueRange</code> option, by default the zoomed flags are also updated correspondingly.
+ It is possible to prevent this by specifying the <code>noZoomFlagChange</code> in the same
+ call to the <code>updateOptions</code> method.
+ </p>
+ <p>
+ The <a href="tests/no-zoom-change.html">no-zoom-change</a> test shows this in operation.
