mira este es el codigo que utilizo, ejemplo:
Código PHP:
<?php
include ("connect.php");
//$spacer = "<hr size='1'>";
$time = time();
$today = date("d-m-Y",$time);
$date = date("mY",$time);
$date_today = date("dmY",$time);
echo "$spacer";
if (!$limit){
$limit = "30";
}
echo "<table border=1 width=600 bgcolor=#DBEDFD ><tr><td width=400 bgcolor=#9FD6FD class=csslink><span class='headline'>Visitas realizadas en los últimos $limit dias:</span></td><td width=120 align=center bgcolor=#FEFBDA class=csslink>Fecha</td><td width=120 align=center bgcolor=#FEFBDA class=csslink>N°Visita</td></tr>";
echo "$spacer";
$result = mysql_query("SELECT * FROM counthits WHERE start like 'no' ORDER BY time DESC LIMIT 0,$limit");
while ($row = mysql_fetch_array($result)){
$time2 = date("d-m-Y",$row[time]);
echo "<tr><td></td><td align=center bgcolor=#F3FA78 class=csslink><span class='time'>$time2</span></td><td align=center bgcolor=#F3FA78 class=csslink>$row[userstoday]</td></tr>";
$dias=$row["userstoday"];//dato a mostrar
//*********************inlusion de script para graficar************
include ("jpgraph/src/jpgraph.php");
include ("jpgraph/src/jpgraph_bar.php");
//$dias=$_GET["dias"];
$datay=array($dias);
//echo"<img src=cont.php?op=visita_30&dias=$dias>";
//Create the graph. These two calls are always required
$graph = new Graph(300,200,"auto");
$graph->SetScale("textlin");
// Add a drop shadow
$graph->SetShadow();
// Adjust the margin a bit to make more room for titles
$graph->img->SetMargin(40,30,20,40);
// Create a bar pot
$bplot = new BarPlot($datay);
// Adjust fill color
$bplot->SetFillColor('orange');
// Setup values
$bplot->value->Show();
$bplot->value->SetFormat('%d');
$bplot->value->SetFont(FF_FONT1,FS_BOLD);
// Center the values in the bar
$bplot->SetValuePos('center');
// Make the bar a little bit wider
$bplot->SetWidth(0.7);
$graph->Add($bplot);
// Setup the titles
$graph->title->Set("Centered values for bars");
$graph->xaxis->title->Set("X-title");
$graph->yaxis->title->Set("Y-title");
$graph->title->SetFont(FF_FONT1,FS_BOLD);
$graph->yaxis->title->SetFont(FF_FONT1,FS_BOLD);
$graph->xaxis->title->SetFont(FF_FONT1,FS_BOLD);
// Display the graph
$graph->Stroke();
}
