Post Array of Time
Hello, I've noticed that using the library to process time values with the following format: hh:mm:ss, the graph is not properly visualized.
Someone can tell me how to avoid this?

This is the code i have produced:

/* Library settings */
define("CLASS_PATH", "../../../class");
define("FONT_PATH", "../../../fonts");

/* pChart library inclusions */

/* Create and populate the pData object */
$MyData = new pData(); 
//print "::pData";
$curData = date("Y-m-d");
/* Connect to the MySQL database */
$db = mysql_connect("localhost", "root", "password");

/* Build the query that will returns the data to graph */
$Requete = "SELECT * FROM test.eo_data WHERE uid=1 and data='".$curData."';";
//print $Requete;
$Result  = mysql_query($Requete,$db);
//print $Result;
while($row = mysql_fetch_array($Result))
  //print_r ($row);
  /* Get the data from the query result */
     $ora = $ora.",".$row["ora"];
    }else $ora = $row["ora"];
     $energia = $energia.",".$row["energia_conteggiata"];
    }else $energia = $row["energia_conteggiata"];
     $fatpot = $fatpot.",".$row["fattore_potenza"];
    }else $fatpot = $row["fattore_potenza"];
     $tens = $tens.",".$row["tensione"];
    }else $tens = $row["tensione"];

/* Save the data in the pData array */
$MyData->addPoints(array($energia),"Energia Conteggiata");
$MyData->addPoints(array($fatpot),"Fattore Potenza");
/* Put the timestamp column on the abscissa axis */
//print "::Load done settings";

/* Create the pChart object */
$myPicture = new pImage(800,230,$MyData);

/* Retrieve the image map */
if (isset($_GET["ImageMap"]) || isset($_POST["ImageMap"]))

/* Set the image map name */

/* Turn of Antialiasing */
$myPicture->Antialias = FALSE;

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

/* Overlay with a gradient */
$Settings = array("StartR"=>219, "StartG"=>231, "StartB"=>139, "EndR"=>1, "EndG"=>138, "EndB"=>68, "Alpha"=>50);

/* Add a border to the picture */

/* Set the default font */

/* Define the chart area */

/* Draw the scale */
$scaleSettings = array("GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE);

/* Write the chart legend */

/* Turn on shadow computing */

/* Draw the chart */
$Settings = array("RecordImageMap"=>TRUE);

/* Render the picture (choose the best way) */

In particular i expected six bar related to two differents times.

Attached the graph produced!!
Another question, the data scale is automatically adjusted or are there any functions that i can use to do this?

Thank you
