    Line chart: Show missing data without missing data

    yves crutain

      I have a continuous data set by day with different periods that may or may not be continuous.

      On my exemple, period 1 is made of 2 parts interrupted by another modality.


      I would like to have an interruption of line when there is an interruption by another modality.


      When I try to do a line chart, the graph is considered at the same time a different period and a similar period. The option "show missing data" is then not working.
