This was introduced to provide a fast way to identify constant datasets and the extent that non-constant datasets vary.</p> <h3>Parameters</h3> ds - the dataset to measure the extent rank 1 or rank 2 bins <br> wds - a weights dataset, containing zero where the data is not valid, positive non-zero otherwise. If null, then all finite data is treated as valid. <br> range - if non-null, return the union of this range and the extent. This must not contain fill! <h3>Returns:</h3> two element, rank 1 "bins" dataset. <h3>See Also:</h3> <a href='null'>extent(QDataSet, QDataSet, QDataSet)</a> <br> <br><br> <a href="https://github.com/autoplot/dev/search?q=extentSimple&unscoped_q=extentSimple">[search for examples]</a> <a href="https://github.com/autoplot/documentation/tree/master/javadoc/org/das2/qds/ops/Ops_e.md">[view on GitHub]</a> <a href="http://www-pw.physics.uiowa.edu/~jbf/autoplot/javadoc2018/org/das2/qds/ops/Ops.html#extentSimple">[view on old javadoc]</a> <a href="https://sourceforge.net/p/autoplot/code/HEAD/tree/autoplot/trunk/QDataSet/src/org/das2/qds/ops/Ops.java#l10247">[view source]</a> <br> <br> extentSimple( <a href='http://www-pw.physics.uiowa.edu/~jbf/autoplot/doc/org/das2/qds/QDataSet.html'>QDataSet</a> ds, <a href='http://www-pw.physics.uiowa.edu/~jbf/autoplot/doc/org/das2/qds/QDataSet.html'>QDataSet</a> range ) → <a href='http://www-pw.physics.uiowa.edu/~jbf/autoplot/doc/org/das2/qds/QDataSet.html'>QDataSet</a><br>
