<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>A plottable representing a two-dimensional color map in a plot. </p>
<div class="image">
<img src="QCPColorMap.png" alt="QCPColorMap.png"/>
</div>
<p>The data is stored in the class <a class="el" href="classQCPColorMapData.html">QCPColorMapData</a>, which can be accessed via the <a class="el" href="classQCPColorMap.html#a047d7eb3ae657f93f2f39b5e68b79451">data()</a> method.</p>
<p>A color map has three dimensions to represent a data point: The <em>key</em> dimension, the <em>value</em> dimension and the <em>data</em> dimension. As with other plottables such as graphs, <em>key</em> and <em>value</em> correspond to two orthogonal axes 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 that you specify in the <a class="el" href="classQCPColorMap.html" title="A plottable representing a two-dimensional color map in a plot. ">QCPColorMap</a> constructor. The <em>data</em> dimension however is encoded as the color of the point at (<em>key</em>, <em>value</em>).</p>
<p>Set the number of points (or <em>cells</em>) in the key/value dimension via <a class="el" href="classQCPColorMapData.html#a0d9ff35c299d0478b682bfbcdd9c097e">QCPColorMapData::setSize</a>. The plot coordinate range over which these points will be displayed is specified via <a class="el" href="classQCPColorMapData.html#aad9c1c7c703c1339489fc730517c83d4">QCPColorMapData::setRange</a>. The first cell will be centered on the lower range boundary and the last cell will be centered on the upper range boundary. The data can be set by either accessing the cells directly with <a class="el" href="classQCPColorMapData.html#a8e75eaf8746596319032a93f3d2d0683">QCPColorMapData::setCell</a> or by addressing the cells via their plot coordinates with <a class="el" href="classQCPColorMapData.html#afd2083ccfd6987ec94aa7ef8e91ca39a">QCPColorMapData::setData</a>. If possible, you should prefer setCell, since it doesn't need to do any coordinate transformation and thus performs a bit better.</p>
<p>The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed) key and value axes.</p>
<p>To show the user which colors correspond to which <em>data</em> values, a <a class="el" href="classQCPColorScale.html">QCPColorScale</a> is typically placed to the right of the axis rect. See the documentation there for details on how to add and use a color scale.</p>
<h1><a class="anchor" id="qcpcolormap-appearance"></a>
Changing the appearance</h1>
<p>The central part of the appearance is the color gradient, which can be specified via <a class="el" href="classQCPColorMap.html#a7313c78360471cead3576341a2c50377">setGradient</a>. See the documentation of <a class="el" href="classQCPColorGradient.html">QCPColorGradient</a> for details on configuring a color gradient.</p>
<p>The <em>data</em> range that is mapped to the colors of the gradient can be specified with <a class="el" href="classQCPColorMap.html#a980b42837821159786a85b4b7dcb8774">setDataRange</a>. To make the data range encompass the whole data set minimum to maximum, call <a class="el" href="classQCPColorMap.html#a856608fa3dd1cc290bcd5f29a5575774">rescaleDataRange</a>.</p>
<h1><a class="anchor" id="qcpcolormap-transparency"></a>
Transparency</h1>
<p>Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha values for color stops of the <a class="el" href="classQCPColorGradient.html">QCPColorGradient</a>, via the regular QColor interface. This will cause the color map data which gets mapped to colors around those color stops to appear with the accordingly interpolated transparency.</p>
<p>On the other hand you can also directly apply an alpha value to each cell independent of its data, by using the alpha map feature of <a class="el" href="classQCPColorMapData.html">QCPColorMapData</a>. The relevant methods are <a class="el" href="classQCPColorMapData.html#aaf7de5b34c58f38d8f4c1ceb064a876c">QCPColorMapData::setAlpha</a>, <a class="el" href="classQCPColorMapData.html#a93e2a549d7702bc849cd48a585294657">QCPColorMapData::fillAlpha</a> and <a class="el" href="classQCPColorMapData.html#a14d08b9c3720cd719400079b86d3906b">QCPColorMapData::clearAlpha()</a>.</p>
<p>The two transparencies will be joined together in the plot and otherwise not interfere with each other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes simultaneously, will result in a total transparency of 25% (64/255).</p>
<h1><a class="anchor" id="qcpcolormap-usage"></a>

For performance reasons, however, they are only updated in an expanding fashion. So the buffered maximum can only increase and the buffered minimum can only decrease. In consequence, changes to the data that actually lower the maximum of the data set (by overwriting the cell holding the current maximum with a smaller value), aren't recognized and the buffered maximum overestimates the true maximum of the data set. The same happens for the buffered minimum. To recalculate the true minimum and maximum by explicitly looking at each cell, the method <a class="el" href="classQCPColorMapData.html#ab235ade8a4d64bd3adb26a99b3dd57ee">QCPColorMapData::recalculateDataBounds</a> can be used.

<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 <a class="el" href="classQCPAbstractPlottable.html#a16aaad02456aa23a759efd1ac90c79bf">selectEvent</a>/<a class="el" href="classQCPAbstractPlottable.html#a6fa0d0f95560ea8b01ee13f296dab2b1">deselectEvent</a> 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="classQCPColorMap.html#aba91ea58b489031157ecb777fe79e309">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>In the case of 1D Plottables (<a class="el" href="classQCPAbstractPlottable1D.html">QCPAbstractPlottable1D</a>, like <a class="el" href="classQCPGraph.html">QCPGraph</a> or <a class="el" href="classQCPBars.html">QCPBars</a>) <em>details</em> will be set to a <a class="el" href="classQCPDataSelection.html">QCPDataSelection</a>, describing the closest data point to <em>pos</em>.</p>
<p>You may pass 0 as <em>details</em> to indicate that you are not interested in those selection details.</p>
