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.
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. 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. 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. MissingValuesPolicyIgnored (internal value, do not use) | MissingValuesAreBridged | |

| void LineAttributes::setAreaBoundingDataset | ( | int | dataset | ) |
Sets the lower or upper (depending on the displayed value being positive or negative, resp.
) bounding line (i.e., the dataset with the line data). The area is then drawn between this line and the line of the specified dataset. Pass -1 to draw the area between this line and the zero line.
