drawScatterSplineChart - Draw a scatter spline chart

This function allows you to draw a scatter spline chart. All the drawing parameters are given trough a $Format array. To learn more about this please read the Format array guide.

Calling this function
drawScatterSplineChart($Format="");
Where :

Format is an array containing the drawing parameters of the chart.


Customisation array - Tune up your chart!

It is possible to customize the chart rendering by playing with this array. Providing a detailled configuration is not mandatory. You‘ll see below a representation of all the customization possible :

You can enable image map recording by setting RecordImageMap to TRUE.

Sample script


 /* pChart library inclusions */
 include("../class/pData.class.php");
 include("../class/pDraw.class.php");
 include("../class/pImage.class.php");
 include("../class/pScatter.class.php");

 /* Create the pData object */
 $myData = new pData();  

 /* Create the X axis and the binded series */
 for ($i=0;$i<=360;$i=$i+90) { $myData->addPoints(rand(1,30),"Probe 1"); }

 $myData->setSerieOnAxis("Probe 3",1);
 $myData->setAxisName(1,"Degree");
 $myData->setAxisXY(1,AXIS_Y);
 $myData->setAxisUnit(1,"°");
 $myData->setAxisPosition(1,AXIS_POSITION_RIGHT);

 /* Create the 1st scatter chart binding */

 $myData->setScatterSerieDescription(0,"This year");
 $myData->setScatterSerieTicks(0,4);

 /* Create the 2nd scatter chart binding */
 $myData->setScatterSerie("Probe 2","Probe 3",1);
 $myData->setScatterSerieDescription(1,"Last Year");

 /* Create the pChart object */
 $myPicture = new pImage(400,400,$myData);

 /* Draw the background */
 $Settings = array("R"=>170, "G"=>183, "B"=>87, "Dash"=>1, "DashR"=>190, "DashG"=>203, "DashB"=>107);

 /* Add a border to the picture */
 $myPicture->drawRectangle(0,0,399,399,array("R"=>0,"G"=>0,"B"=>0));

 /* Set the default font */
 $myPicture->setFontProperties(array("FontName"=>"../fonts/pf_arma_five.ttf","FontSize"=>6));
 
 /* Set the graph area */
 $myPicture->setGraphArea(50,50,350,350);

 /* Create the Scatter chart object */
 $myScatter = new pScatter($myPicture,$myData);

 /* Draw the scale */
 $myScatter->drawScatterScale();

 /* Turn on shadow computing */
 $myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));

 /* Draw a scatter plot chart */
 $myScatter->drawScatterSplineChart();
 $myScatter->drawScatterPlotChart();

 /* Draw the legend */
 $myScatter->drawScatterLegend(280,380,array("Mode"=>LEGEND_HORIZONTAL,"Style"=>LEGEND_NOBORDER));

 /* Render the picture (choose the best way) */
 $myPicture->autoOutput("pictures/example.drawScatterSplineChart.png");
