void DataCurve::addErrorBars

(

DataCurve *

c

)

[inline]

Adds a single error bars curve to the list of attached error bars.

void DataCurve::clearErrorBars

(

)

Clears the list of attached error bars.

int DataCurve::endRow

(

)

[inline]

QList<DataCurve *> DataCurve::errorBarsList

(

)

[inline]

The list of attached error bars.

bool DataCurve::isFullRange

(

)

void DataCurve::loadData

(

)

[virtual]

Reimplemented in BoxCurve, QwtErrorPlotCurve, QwtHistogram, QwtPieCurve, and VectorCurve.

QString DataCurve::plotAssociation

(

)

[virtual]

A list of data sources for this curve.

Elements must be in either of the following forms:

• <id of X column> "(X)," <id of Y column> "(Y)" [ "," <id of error column> ("(xErr)" | "(yErr)") ]
• <id of Xstart column> "(X)," <id of Ystart column>"(Y)," <id of Xend column> "(X)," <id of Yend column> "(Y)"
  (denoting start and end coordinates for the VectXYXY style)
• <id of Xstart column> "(X)," <id of Ystart column> "(Y)," <id of angle column> "(A)," <id of magnitude column> "(M)"
  (denoting start coordinates, angle in radians and length for the VectXYAM style)

Column ids are of the form '<name of table> "_" <name of column>'.
