Filter operator does not update statistics

if I filter the dataset then statistics for polynomial column of the dataset are not updated. The result is that if I plot the chart and axis is based on this column then axis is not auto ranged i.e. data points are only on the left side. It works with some sets and with some dont. The workaround is to filter everything, store it in excel and then load it again. But you can imagine that it is not ideal. In the picture you can see the statistics

    you can add a "Remove Unused Values" operator to drop the non-existing values.

    hi @ingtomaschladek can you please re-post your XML and your dataset? That XML you posted is corrupted. Just go to the XML panel and copy what's there (or attach your .rmp file here).
