<div class="textblock"><p>The abstract base class for all data representing objects in a plot. </p>
<p>It defines a very basic interface like name, pen, brush, visibility etc. Since this class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to create new ways of displaying data (see "Creating own plottables" below).</p>
<p>All further specifics are in the subclasses, for example: </p>
<ul>
<li>A normal graph with possibly a line, scatter points and error bars: <a class="el" href="classQCPGraph.html">QCPGraph</a> (typically created with <a class="el" href="classQCustomPlot.html#a6fb2873d35a8a8089842d81a70a54167">QCustomPlot::addGraph</a>) </li>
<li>A parametric curve: <a class="el" href="classQCPCurve.html">QCPCurve</a> </li>
<li>A bar chart: <a class="el" href="classQCPBars.html">QCPBars</a> </li>
<li>A statistical box plot: <a class="el" href="classQCPStatisticalBox.html">QCPStatisticalBox</a> </li>
<li>A color encoded two-dimensional map: <a class="el" href="classQCPColorMap.html">QCPColorMap</a> </li>
<li>An OHLC/Candlestick chart: <a class="el" href="classQCPFinancial.html">QCPFinancial</a></li>
</ul>
<h1><a class="anchor" id="plottables-subclassing"></a>
Creating own plottables</h1>
<p>To create an own plottable, you implement a subclass of <a class="el" href="classQCPAbstractPlottable.html" title="The abstract base class for all data representing objects in a plot. ">QCPAbstractPlottable</a>. These are the pure virtual functions, you must implement: </p>
<ul>
<li><a class="el" href="classQCPAbstractPlottable.html#a86e5b8fd4b6ff4f4084e7ea4c573fc53">clearData</a> </li>
<li><a class="el" href="classQCPAbstractPlottable.html#a38efe9641d972992a3d44204bc80ec1d">selectTest</a> </li>
<li><a class="el" href="classQCPAbstractPlottable.html#acbab5e30dcd04fd302b4a5902ac2c482">draw</a> </li>
<li><a class="el" href="classQCPAbstractPlottable.html#a9a450783fd9ed539e589999fd390cdf7">drawLegendIcon</a> </li>
<li><a class="el" href="classQCPAbstractPlottable.html#a345d702b2e7e12c8cfdddff65ba85e8c">getKeyRange</a> </li>
<li><a class="el" href="classQCPAbstractPlottable.html#aa3331b415b5939fe4df60b78831b2799">getValueRange</a></li>
</ul>
<p>See the documentation of those functions for what they need to do.</p>
<p>For drawing your plot, you can use the <a class="el" href="classQCPAbstractPlottable.html#ade710a776104b14c1c835168ce1bfc5c">coordsToPixels</a> functions to translate a point in plot coordinates to pixel coordinates. This function is quite convenient, because it takes the orientation of the key and value axes into account for you (x and y are swapped when the key axis is vertical and the value axis horizontal). If you are worried about performance (i.e. you need to translate many points in a loop like <a class="el" href="classQCPGraph.html" title="A plottable representing a graph in a plot. ">QCPGraph</a>), you can directly use <a class="el" href="classQCPAxis.html#a985ae693b842fb0422b4390fe36d299a">QCPAxis::coordToPixel</a>. However, you must then take care about the orientation of the axis yourself.</p>
<p>Here are some important members you inherit from <a class="el" href="classQCPAbstractPlottable.html" title="The abstract base class for all data representing objects in a plot. ">QCPAbstractPlottable</a>: </p>

<p>This function is used to decide whether a click hits a layerable object or not.</p>
<p><em>pos</em> is a point in pixel coordinates on the <a class="el" href="classQCustomPlot.html" title="The central class of the library. This is the QWidget which displays the plot and interacts with the ...">QCustomPlot</a> surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn't be determined, -1.0 is returned. Further, if <em>onlySelectable</em> is true and the object is not selectable, -1.0 is returned, too.</p>
<p>If the object is represented not by single lines but by an area like a <a class="el" href="classQCPItemText.html">QCPItemText</a> or the bars of a <a class="el" href="classQCPBars.html">QCPBars</a> plottable, a click inside the area should also be considered a hit. In these cases this function thus returns a constant value greater zero but still below the parent plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).</p>
<p>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*selectionTolerance).</p>
<p>The actual setting of the selection state is not done by this function. This is handled by the parent <a class="el" href="classQCustomPlot.html" title="The central class of the library. This is the QWidget which displays the plot and interacts with the ...">QCustomPlot</a> when the mouseReleaseEvent occurs, and the finally selected object is notified via the selectEvent/deselectEvent methods.</p>
<p><em>details</em> is an optional output parameter. Every layerable subclass may place any information in <em>details</em>. This information will be passed to <a class="el" href="classQCPAbstractPlottable.html#a16aaad02456aa23a759efd1ac90c79bf">selectEvent</a> when the parent <a class="el" href="classQCustomPlot.html" title="The central class of the library. This is the QWidget which displays the plot and interacts with the ...">QCustomPlot</a> decides on the basis of this selectTest call, that the object was successfully selected. The subsequent call to <a class="el" href="classQCPAbstractPlottable.html#a16aaad02456aa23a759efd1ac90c79bf">selectEvent</a> will carry the <em>details</em>. This is useful for multi-part objects (like <a class="el" href="classQCPAxis.html" title="Manages a single axis inside a QCustomPlot. ">QCPAxis</a>). This way, a possibly complex calculation to decide which part was clicked is only done once in <a class="el" href="classQCPAbstractPlottable.html#a38efe9641d972992a3d44204bc80ec1d">selectTest</a>. The result (i.e. the actually clicked part) can then be placed in <em>details</em>. So in the subsequent <a class="el" href="classQCPAbstractPlottable.html#a16aaad02456aa23a759efd1ac90c79bf">selectEvent</a>, the decision which part was selected doesn't have to be done a second time for a single selection operation.</p>
<p>You may pass 0 as <em>details</em> to indicate that you are not interested in those selection details.</p>

<p>This event is called when the layerable shall be selected, as a consequence of a click by the user. Subclasses should react to it by setting their selection state appropriately. The default implementation does nothing.</p>
<p><em>event</em> is the mouse event that caused the selection. <em>additive</em> indicates, whether the user was holding the multi-select-modifier while performing the selection (see <a class="el" href="classQCustomPlot.html#a8fc96e3b5138a06759a2a90c166df516">QCustomPlot::setMultiSelectModifier</a>). if <em>additive</em> is true, the selection state must be toggled (i.e. become selected when unselected and unselected when selected).</p>
<p>Every selectEvent is preceded by a call to <a class="el" href="classQCPAbstractPlottable.html#a38efe9641d972992a3d44204bc80ec1d">selectTest</a>, which has returned positively (i.e. returned a value greater than 0 and less than the selection tolerance of the parent <a class="el" href="classQCustomPlot.html" title="The central class of the library. This is the QWidget which displays the plot and interacts with the ...">QCustomPlot</a>). The <em>details</em> data you output from <a class="el" href="classQCPAbstractPlottable.html#a38efe9641d972992a3d44204bc80ec1d">selectTest</a> is fed back via <em>details</em> here. You may use it to transport any kind of information from the selectTest to the possibly subsequent selectEvent. Usually <em>details</em> is used to transfer which part was clicked, if it is a layerable that has multiple individually selectable parts (like <a class="el" href="classQCPAxis.html" title="Manages a single axis inside a QCustomPlot. ">QCPAxis</a>). This way selectEvent doesn't need to do the calculation again to find out which part was actually clicked.</p>
<p><em>selectionStateChanged</em> is an output parameter. If the pointer is non-null, this function must set the value either to true or false, depending on whether the selection state of this layerable was actually changed. For layerables that only are selectable as a whole and not in parts, this is simple: if <em>additive</em> is true, <em>selectionStateChanged</em> must also be set to true, because the selection toggles. If <em>additive</em> is false, <em>selectionStateChanged</em> is only set to true, if the layerable was previously unselected and now is switched to the selected state.</p>
