Typedef Documentation

§ 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.
