\brief MissingValuesPolicy specifies how a missing value will be shown in a line diagram.
|
||
|
|
|
||
|
|
Missing value is assumed if the data cell contains a QVariant that can not be
|
||
|
|
interpreted as a double, or if the data cell is hidden while its dataset is not hidden.
|
||
|
|
|
||
|
|
\li \c MissingValuesAreBridged the default: No markers will be shown for missing values
|
||
|
|
but the line will be bridged if there is at least one valid cell before and after
|
||
|
|
the missing value(s), otherwise the segment will be hidden.
|
||
|
|
\li \c MissingValuesHideSegments Line segments starting with a missing value will
|
||
|
|
not be shown, and no markers will be shown for missing values, so this will look like
|
||
|
|
a piece of the line is missing.
|
||
|
|
\li \c MissingValuesShownAsZero Missing value(s) will be treated like normal zero values,
|
||
|
|
and markers will shown for them too, so there will be no visible difference between a
|
||
|
|
zero value and a missing value.
|
||
|
|
