Typedef Documentation

QCPBarsDataContainer

Container for storing QCPBarsData points. The data is stored sorted by key.

This template instantiation is the container in which QCPBars holds its data. For details about the generic container, see the documentation of the class template QCPDataContainer.

See also

QCPBarsData, QCPBars::setData

Definition at line 5435 of file qcustomplot.h.

QCPCurveDataContainer

Container for storing QCPCurveData points. The data is stored sorted by t, so the sortKey() (returning t) is different from mainKey() (returning key).

This template instantiation is the container in which QCPCurve holds its data. For details about the generic container, see the documentation of the class template QCPDataContainer.

See also

QCPCurveData, QCPCurve::setData

Definition at line 5256 of file qcustomplot.h.

QCPErrorBarsDataContainer

Container for storing QCPErrorBarsData points. It is a typedef for QVector<QCPErrorBarsData>.

This is the container in which QCPErrorBars holds its data. Unlike most other data containers for plottables, it is not based on QCPDataContainer. This is because the error bars plottable is special in that it doesn't store its own key and value coordinate per error bar. It adopts the key and value from the plottable to which the error bars shall be applied (QCPErrorBars::setDataPlottable). So the stored QCPErrorBarsData doesn't need a sortable key, but merely an index (as QVector provides), which maps one-to-one to the indices of the other plottable's data.

QCPFinancialDataContainer

Container for storing QCPFinancialData points. The data is stored sorted by key.

This template instantiation is the container in which QCPFinancial holds its data. For details about the generic container, see the documentation of the class template QCPDataContainer.

QCPFinancialData, QCPFinancial::setData

Definition at line 5811 of file qcustomplot.h.

QCPGraphDataContainer

Container for storing QCPGraphData points. The data is stored sorted by key.

This template instantiation is the container in which QCPGraph holds its data. For details about the generic container, see the documentation of the class template QCPDataContainer.

See also

QCPGraphData, QCPGraph::setData

Definition at line 5117 of file qcustomplot.h.

QCPStatisticalBoxDataContainer

Container for storing QCPStatisticalBoxData points. The data is stored sorted by key.

This template instantiation is the container in which QCPStatisticalBox holds its data. For details about the generic container, see the documentation of the class template QCPDataContainer.
