"description": "Short form: xFilesFactor()\n\nTakes one metric or a wildcard seriesList and an xFilesFactor value between 0 and 1\n\nWhen a series needs to be consolidated, this sets the fraction of values in an interval that must\nnot be null for the consolidation to be considered valid. If there are not enough values then\nNone will be returned for that interval.\n\n.. code-block:: none\n\n &target=xFilesFactor(Sales.widgets.largeBlue, 0.5)\n &target=Servers.web01.sda1.free_space|consolidateBy('max')|xFilesFactor(0.5)\n\nThe `xFilesFactor` set via this function is used as the default for all functions that accept an\n`xFilesFactor` parameter, all functions that aggregate data across multiple series and/or\nintervals, and `maxDataPoints <render_api.html#maxdatapoints>`_ consolidation.\n\nA default for the entire render request can also be set using the\n`xFilesFactor <render_api.html#xfilesfactor>`_ query parameter.\n\n.. note::\n\n `xFilesFactor` follows the same semantics as in Whisper storage schemas. Setting it to 0 (the\n default) means that only a single value in a given interval needs to be non-null, setting it to\n 1 means that all values in the interval must be non-null. A setting of 0.5 means that at least\n half the values in the interval must be non-null.",
