mistercrunch commented on issue #5888: Display Null values as 0 on Timeseries Charts URL: https://github.com/apache/incubator-superset/issues/5888#issuecomment-422671428 For line chart, there's the resample feature that can help forcing null to zeroes: <img width="549" alt="screen shot 2018-09-18 at 11 27 20 pm" src="https://user-images.githubusercontent.com/487433/45734740-73fb3200-bb9a-11e8-9779-e4bc49914eba.png";> Null handling is trickier than it may seem as people may want: * null to be replaced by 0 * lines in line chat to be broken off, show a line on the left, and a line on the right * lines to skip over missing points, connecting the dots on either side Ultimately we should offer these options in a nice way. For now the resample option and showing markers are ways to mitigate.
