  96. \subsection{Detailed Description}
  97. A plottable representing a parametric curve in a plot.
  98. Unlike \hyperlink{class_q_c_p_graph}{Q\+C\+P\+Graph}, plottables of this type may have multiple points with the same key coordinate, so their visual representation can have {\itshape loops}. This is realized by introducing a third coordinate {\itshape t}, which defines the order of the points described by the other two coordinates {\itshape x} and {\itshape y}.
  99. To plot data, assign it with the \hyperlink{class_q_c_p_curve_a631ac886708460013b30052f49cbc9da}{set\+Data} or \hyperlink{class_q_c_p_curve_a4e24023c3b9ac75440c7a260172c99af}{add\+Data} functions.\hypertarget{class_q_c_p_statistical_box_appearance}{}\subsection{Changing the appearance}\label{class_q_c_p_statistical_box_appearance}
  100. The appearance of the curve is determined by the pen and the brush (\hyperlink{class_q_c_p_abstract_plottable_ab74b09ae4c0e7e13142fe4b5bf46cac7}{set\+Pen}, \hyperlink{class_q_c_p_abstract_plottable_a7a4b92144dca6453a1f0f210e27edc74}{set\+Brush}). \hypertarget{class_q_c_p_statistical_box_usage}{}\subsection{Usage}\label{class_q_c_p_statistical_box_usage}
  101. Like all data representing objects in \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot}, the \hyperlink{class_q_c_p_curve}{Q\+C\+P\+Curve} is a plottable (\hyperlink{class_q_c_p_abstract_plottable}{Q\+C\+P\+Abstract\+Plottable}). So the plottable-\/interface of \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} applies (\hyperlink{class_q_custom_plot_a32de81ff53e263e785b83b52ecd99d6f}{Q\+Custom\+Plot\+::plottable}, \hyperlink{class_q_custom_plot_ab7ad9174f701f9c6f64e378df77927a6}{Q\+Custom\+Plot\+::add\+Plottable}, \hyperlink{class_q_custom_plot_af3dafd56884208474f311d6226513ab2}{Q\+Custom\+Plot\+::remove\+Plottable}, etc.)
  102. Usually, you first create an instance\+:
  103. \begin{DoxyCode}
  104. \hyperlink{class_q_c_p_curve}{QCPCurve} *newCurve = \textcolor{keyword}{new} \hyperlink{class_q_c_p_curve_a36de58e2652b3fa47bdf9187d421d3ce}{QCPCurve}(customPlot->xAxis, customPlot->yAxis);
  105. \end{DoxyCode}
  106. add it to the custom\+Plot with \hyperlink{class_q_custom_plot_ab7ad9174f701f9c6f64e378df77927a6}{Q\+Custom\+Plot\+::add\+Plottable}\+:
  107. \begin{DoxyCode}
  108. customPlot->addPlottable(newCurve);
  109. \end{DoxyCode}
  110. and then modify the properties of the newly created plottable, e.\+g.\+:
  111. \begin{DoxyCode}
  112. newCurve->\hyperlink{class_q_c_p_abstract_plottable_ab79c7ba76bc7fa89a4b3580e12149f1f}{setName}(\textcolor{stringliteral}{"Fermat's Spiral"});
  113. newCurve->\hyperlink{class_q_c_p_curve_a631ac886708460013b30052f49cbc9da}{setData}(tData, xData, yData);

  264. This function is used to decide whether a click hits a layerable object or not.
  265. {\itshape pos} is a point in pixel coordinates on the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn\textquotesingle{}t be determined, -\/1.\+0 is returned. Further, if {\itshape only\+Selectable} is true and the object is not selectable, -\/1.\+0 is returned, too.
  266. If the item is represented not by single lines but by an area like \hyperlink{class_q_c_p_item_rect}{Q\+C\+P\+Item\+Rect} or \hyperlink{class_q_c_p_item_text}{Q\+C\+P\+Item\+Text}, a click inside the area returns a constant value greater zero (typically the selection\+Tolerance of the parent \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} multiplied by 0.\+99). If the click lies outside the area, this function returns -\/1.\+0.
  267. Providing a constant value for area objects allows selecting line objects even when they are obscured by such area objects, by clicking close to the lines (i.\+e. closer than 0.\+99$\ast$selection\+Tolerance).
  268. The actual setting of the selection state is not done by this function. This is handled by the parent \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} when the mouse\+Release\+Event occurs, and the finally selected object is notified via the select\+Event/deselect\+Event methods.
  269. {\itshape details} is an optional output parameter. Every layerable subclass may place any information in {\itshape details}. This information will be passed to select\+Event when the parent \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} decides on the basis of this select\+Test call, that the object was successfully selected. The subsequent call to select\+Event will carry the {\itshape details}. This is useful for multi-\/part objects (like \hyperlink{class_q_c_p_axis}{Q\+C\+P\+Axis}). This way, a possibly complex calculation to decide which part was clicked is only done once in \hyperlink{class_q_c_p_curve_a5af9949e725704811bbc81ecd5970b8e}{select\+Test}. The result (i.\+e. the actually clicked part) can then be placed in {\itshape details}. So in the subsequent select\+Event, the decision which part was selected doesn\textquotesingle{}t have to be done a second time for a single selection operation.
  270. You may pass 0 as {\itshape details} to indicate that you are not interested in those selection details.

  303. Replaces the current data with the provided {\itshape key} and {\itshape value} pairs. The t parameter of each data point will be set to the integer index of the respective key/value pair. \hypertarget{class_q_c_p_curve_a4a377ec863ff81a1875c3094a6177c19}{}\index{Q\+C\+P\+Curve@{Q\+C\+P\+Curve}!set\+Line\+Style@{set\+Line\+Style}}
