[ZEPPELIN-2252] discreteness of line charts
### What is this PR for?
Added a discreteness in the line chart. Correcting the display of the
chart, when the values does not exist at the point (by default Y is set to 0,
at the moment). A value of 0 is unclear (it is real value from data or it is
default value).
