Hello. I have a layer of meteorological stations with temporal information in PostGIS. Some of the stations have variables with null values. In QGIS v2.3 (Ubuntu 13.10), null values are displayed correctly in the attribute table. However, when displaying the label is treated as a value of 0, similarly when I perform an operation interpolation (IDW algorithm from the raster menu), where this result should ignore null values stations.
My question is, is this a bug in QGIS?. Attached a screenshot trying to explain the results of interpolation and labeled, possibly wrong with null values. https://drive.google.com/file/d/0B9J3L0xnIeLZLWRtSkJLeXp1RzA regards, Samuel Mesa, -- --- .~. / v \ // \\ /( )\ ^`~'^
