setAxisName - Define the name of one Y Axis

This function allows you to set the name of one Y Axis. This name will be displayed when drawing the chart area. Values on this axis are automatically computed by the scaling algorithm.

By default all new series are binded to the default axis with an ID of 0. You can bind a serie to another axis using the setSerieOnAxis function.

Calling this function

setAxisName($AxisID,$Name);

Where :

AxisID is the ID of the axis we want to name.

Name is the name that will be put on the axis.

Sample script #1

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

 /* The default axis will be named "Samples" */
 $MyData->setAxisName(0,"Samples");

Sample script #2

 $MyData = new pData();  

 /* Prepare some nice data & axis config */
 $MyData->addPoints(array(24,-25,26,25,25),"Temperature");
 $MyData->addPoints(array(1,2,VOID,9,10),"Humidity 1");
 $MyData->addPoints(array(1,VOID,7,-9,0),"Humidity 2");
 $MyData->addPoints(array(-1,-1,-1,-1,-1),"Humidity 3");
 $MyData->addPoints(array(0,0,0,0,0),"Vide");
 $MyData->setSerieOnAxis("Temperature",0);
 $MyData->setSerieOnAxis("Humidity 1",1);
 $MyData->setSerieOnAxis("Humidity 2",1);
 $MyData->setSerieOnAxis("Humidity 3",1);
 $MyData->setSerieOnAxis("Vide",2);
 $MyData->setAxisPosition(2,AXIS_POSITION_RIGHT);
 $MyData->setAxisName(0,"Temperature");
 $MyData->setAxisName(1,"Humidity");
 $MyData->setAxisName(2,"Empty value");

 /* Bind a data serie to the X axis */
 $MyData->addPoints(array("Jan","Feb","Mar","Apr","May","Jun"),"Labels");
 $MyData->setSerieDescription("Labels","My labels");
 $MyData->setAbscissa("Labels");

 /* Define the graph area and do some makeup */
 $myPicture->setGraphArea(90,60,660,190);
 $myPicture->drawText(350,55,"My chart title",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));
 $myPicture->drawFilledRectangle(90,60,660,190,array("R"=>255,"G"=>255,"B"=>255,"Surrounding"=>-200,"Alpha"=>10));

 /* Compute and draw the scale */
 $myPicture->drawScale(array("DrawYLines"=>array(0)));
