PHP - How To Get Google Chart To Display
Good afternoon,
I am working on a project that gives the user a data table and a google chart (using the api) based on what the user selects for a <select> <option>.
Index.PHP code:
<form>
<select name="users" onchange="showUser(this.value);drawChart();">
<option value=""> Select a Metal: </option>
<?php
//connection details
$query = "SELECT TOP(31) tblMetalPrice.MetalSourceID, tblMetalSource.MetalSourceName from tblMetalPrice INNER JOIN tblMetalSource ON tblMetalPrice.MetalSourceID=tblMetalSource.MetalSourceID ORDER BY tblMetalPrice.DateCreated DESC ";
$result = sqlsrv_query( $conn, $query);
while( $row = sqlsrv_fetch_object ($result)) {
echo "<option value='".$row->MetalSourceID ."'>". $row->MetalSourceName ."</option>";
}
sqlsrv_close( $conn);
?>
</select>
</form>
<div id="chart_div"></div>
<div id="txtHint"><b>Past metal information will be generated below.</b></div>
this works fine and generates the list in the select option dropdown
Script to get table contents:
<script>
function showUser(str) {
if (str=="") {
document.getElementById("txtHint").innerHTML="";
return;
}
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else { // code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4 && xmlhttp.status==200) {
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","scripts/gettabledata001.php?q="+str,true);
xmlhttp.send();
}
</script>
this also works fine and generates the table contents based on 'q' value from the select dropdown.
Google API script:
<script type="text/javascript">
// Load the Visualization API and the piechart,table package.
google.load('visualization', '1', {'packages':['corechart']});
google.setOnLoadCallback(drawChart());
function drawChart() {
var jsonData = $.ajax({
url: "scripts/getgraphdata.php",
dataType:"json",
data: "q="+num,
async: false
}).responseText;
// Instantiate and draw our pie chart, passing in some options.
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, {width: 400, height: 240});
}
</script>
getgraphdata.php script:
$q = intval($_GET['q']);
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
$query ="SELECT TOP(30) tblMetalPrice.MetalSourceID, tblMetalPrice.DateCreated, tblMetalPrice.UnitPrice, tblMetalPrice.HighUnitPrice, tblMetalSource.MetalSourceName FROM tblMetalPrice INNER JOIN tblMetalSource ON tblMetalPrice.MetalSourceID = tblMetalSource.MetalSourceID WHERE tblMetalPrice.MetalSourceID = '".$q."' ORDER BY tblMetalPrice.DateCreated DESC";
$result = sqlsrv_query($conn, $query);
echo "{ \"cols\": [ {\"id\":\"\",\"label\":\"Date\",\"pattern\":\"\",\"type\":\"string\"}, {\"id\":\"\",\"label\":\"Unit Price\",\"pattern\":\"\",\"type\":\"number\"} ], \"rows\": [ ";
$total_rows = sqlsrv_num_rows($result);
$row_num = 0;
while($row = sqlsrv_fetch_object($result)){
$row_num++;
if ($row_num == $total_rows){
echo "{\"c\":[{\"v\":\"" . $row->DateCreated->format('d-m-Y') ."\",\"f\":null},{\"v\":" . $row->UnitPrice . ",\"f\":null}]}";
} else {
echo "{\"c\":[{\"v\":\"" . $row->DateCreated->format('d-m-Y') ."\",\"f\":null},{\"v\":" . $row->UnitPrice . ",\"f\":null}]}, ";
}
}
echo " ] }";
sqlsrv_close( $conn);
When ever i try these they don't work the getgraphdata.php scripts runs fine the issue I believe but may be totally wrong may be done to the google api script that should generate the chart but doesn't.
Can anyone help here I've been trying to sort this for a few days now and losing confidence in myself rapidly.
Thanks

Newbie needs some help pls. Searched far and wide, seen others ask but no answer (maybe too obvious).
I have a simple function to do some basic math (its for young children)
<?php for($i=0;$i<$_POST['period'];$i++):
$year=$current_year+$i; I recently created a site that creates charts with google charts api and information it collects from a database that the owner of the site inputs. All works well except for the left and right axis top numbers. These display odd top numbers and I am wondering what it would take to get it to round the number up to the nearest 100 so that it displays evenly. I set the code to go 100 over and I think that somewhere in here is my problem. If a user inputs a number of 255 and that number is the highest within the chart data then the top number displays 355. It displays both top number 255 and 355. Now what this does is makes the gains look higher that they actually are because it goes from 200, 255 and then 355. Please see example out put here I am sure there must be away to dynamically add the axis labels without it pulling in the info from the data itself right? I have asked this very same question on google code and still know answer. Here is an example of the code I am using. <?php $id_entity = $_product->getId(); $chart_num_rows = 0; $db_obj = mysql_connect('localhost', 'XXX', 'XXX'); mysql_select_db('XXXX', $db_obj); $query = " SELECT a.frontend_label AS frontend_label, b.value AS value FROM XXX AS a, XXX AS b WHERE a.attribute_id = b.attribute_id && b.entity_id = ".$id_entity." && a.attribute_id BETWEEN 564 AND 568 ORDER BY a.attribute_id ASC "; $result = mysql_query($query); if(mysql_num_rows($result) != 0) { @$chart_num_rows = mysql_num_rows($result); } if($chart_num_rows != 0) { $max = 0; $min = 0; $array = array(); for($i = 0; $i < $chart_num_rows; $i++) { $row = mysql_fetch_object($result); $clean = str_replace(" ", '', $row->value); $explode = explode(',', $clean); if($i == 4) { $min = min($explode); $max = max($explode); } else { if($min < min($explode)) { $min = min($explode); } if($max < max($explode)) { $min = max($explode); } } $array[$i][0] = $row->frontend_label; /* Labels */ $array[$i][1] = $clean; /* Line Data */ $array[$i][2] = str_replace(',', '|', $clean); /* Labels */ } $count = 100; $left_right = ''; while($count < $max) { $left_right .= $count.'|'; $count = ($count + 100); } $left_right .= $max.'|'.($max + 100); $output = '<img src="http://chart.apis.google.com/chart? cht=lc&chd=t:'.$array[1][1].'|'.$array[2][1].'|'.$array[3][1].'|'. $array[4][1]; $output .= '&chls=3|3|3|3|3|3,6,3&chf=bg,s,FFFFFF&chxl=0:|'.$array[0] [2].'|1:|'.$left_right.'|2:|'.$left_right; $output .= '&chs=575x300&chf=bg,s,FFFFFF&chco=444444,444444,0000FF, 0000FF&chxt=x,y,r&chds=50,'.($max + 100); $output .= '&chm=h,76A4FB,0,0:1:.2,2,-1|V,76A4FB,0,::2,0.5,-1"><br / ><br />'; } else { $output = 'There are no current statistics available for this chart.'; } echo $output; ?> Following on from my problem with another Google Chart which jay0316 kindly helped with, I have another issue which I am hoping that someone might be able to help me with.
I am trying to put together a site for my wife to manage her diabetes and insulin intake. We want to monitor her blood/sugar glucose over periods of time (but with notes that she includes that can help monitor reasons for outlying results such as illness), so I am trying to include a Google Annotation Chart to do this, drawing on blood/glucose readings stored in a Database.

Hello, In a MySQL table I have the following rows: Item name Item price Milk 1.05 Butter 1.50 Lettuce 0.70 Butter 1.55 Bread 0.65 Chicken 3.50 Milk 1.00 Coca Cola 1.20 Apples 0.90 Toothpaste 1.00 Oranges 0.80 Milk 1.00 What I'm looking to do is collect all of the milks, all of the butters, etc and give a $total_price_spent_on value for each product, so for milk we'd have 3.05, for oranges we'd have 0.80, and so on until all items on the list have been totalled. Then I want to select the most expensive 3 totals, display them in a pie chart, and all other items to be listed under an "other" label. Any pointers as to how to go about this? Many thanks I wish to access the following chart by the number and the headings names. field text mysqlfield 1 username Please enter a username un 2 name Please enter you name nm 3 age Please enter your age ag 4 town What town do you live in tw 5 postcode What is your postcode pc I place the field and the text in to a form and use the mysqlfield to placce the data in the mysql database. what i do not know is how to store the array data and how to access it.

Thanks in advance This question is part PHP, part MySQL. I have a survey_responses table...
- id - survey_id - question_id - member_id - response
For satisfaction questions (i.e. 1 = Strongly Disagree, 2 = Disagree, 3 = Neither, 4 = Agree, 5 = Strongly Agree), I'm trying to figure out how to get the counts for each of those responses into PHP so I can then feed them to a Bar Chart I hope to create with HTML/CSS. 1.) Should I create some kind of loop in PHP, and look for each value (e.g. 1 = Strongly Disagree) and one at a time plug them into variables called: $stronglyDisagree, $disagree, $neighter, $agree, $stronglyAgree?
2.) Or do I first need a "cross-tab" query in MySQL?
3.) Would this be easier if the database values were in a PHP array?
Not sure where to begin with this, and more importantly, I want to make sure that my data model in MySQL is sufficient so i can do reporting like this!!
Thanks.
This topic has been moved to Other Libraries and Frameworks. http://www.phpfreaks.com/forums/index.php?topic=358786.0 Hello, I'm trying to work out a method of displaying a pie chart depending on the values in an array by looping for a different value of $i, here's what I have so far: for($i = 0; $i < 11; $i++) { $colour = $i; $fraction = ($pie_data[$i]/$total); $pie_angle = $fraction*360; ImageFilledArc($myImage, 100, 100, 200, 180, STARTANGLE, ENDANGLE, $colour, IMG_ARC_PIE); } As you can see I've got fractions, which I'm converting into an angle. However, I can't think of a way to have the startangle and endangle parameters of the ImageFilledArc function depend on all of the previous pie angles, because I'm hoping this pie chart can vary as pieces of data forming each wedge (and each fraction) change.

I am using the pChart (http://www.pchart.net/) PHP class framework to create a pie chart using database values which I have extracted using this select query:
$query = "SELECT Labels, COUNT(quantity) as quantity FROM inventory GROUP BY Labels";
$result = $mysqli->query($query);
/* associative array */
while($row = $result->fetch_assoc())
{
$titles = (array_values($row));
$count = $row['quantity'];
$Labels = $row['Labels'];
print_r($count);
print_r($Labels);
}
The implementation procedure for the pChart framework requires two array data sources as shown in code sample below:
The absissa series,
and ordinate series
/* Create and populate the pData object */
$MyData = new pData();
$MyData->addPoints(array(40,60,15,10,6,4,80),"quantity");
$MyData->setSerieDescription("quantity","Application A");
/* Define the absissa series */
$MyData->addPoints(array("Table","Chair","Bed","Stove","Lamp","Rug", "Others"),"Labels");
$MyData->setAbscissa("Labels");
Within this context, how may I get the absissa and ordinate values as arrays into the pChart for creations of the pie chart?
Thanks
Hi, I found a couple of topics in the search on this but can't resolve my problem. I have a cart and want to mail it to myself and the client. The cart I'm using works fine but the moment I "check out" (mail the order) it gives a error. I build an error trap but see nothing wrong then I tried a different way to send the order in html with no avail. 6x files I use: Index.php -The products I'm selling and "add to chart" Cart.php - To update and display the products in the basket SendOrder.php - To mail the cart etc. to me and client as the main files and some functions, db connection and global's... 1) Index.php by Simon Mayer <?php // Start the session session_start(); // Include MySQL class require_once('inc/mysql.class.php'); // Include database connection require_once('inc/global.inc.php'); // Include functions require_once('inc/functions.inc.php'); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>MedSET Store</title> <link rel="stylesheet" href="css/styles.css" > </head> <body> <div id="shoppingcart"> <h1>Your Shopping Cart</h1> <?php echo writeShoppingCart(); ?> </div> <div id="booklist"> <h1>Products</h1> <?php $sql = 'SELECT * FROM books ORDER BY id'; $result = $db->query($sql); $output[] = '<ul>'; while ($row = $result->fetch()) { $output[] = '<li>"'.$row['title'].'" by '.$row['author'].': £'.$row['price'].'<br /><a href="cart.php?action=add&id='.$row['id'].'">Add to cart</a></li>'; } $output[] = '</ul>'; echo join('',$output); ?> </div> </body> </html> 2)Cart.php by Simon Mayer <?php // Start the session session_start(); // Include MySQL class require_once('inc/mysql.class.php'); // Include database connection require_once('inc/global.inc.php'); // Include functions require_once('inc/functions.inc.php'); // Process actions $cart = $_SESSION['cart']; $action = $_GET['action']; switch ($action) { case 'add': if ($cart) { $cart .= ','.$_GET['id']; } else { $cart = $_GET['id']; } break; case 'delete': if ($cart) { $items = explode(',',$cart); $newcart = ''; foreach ($items as $item) { if ($_GET['id'] != $item) { if ($newcart != '') { $newcart .= ','.$item; } else { $newcart = $item; } } } $cart = $newcart; } break; case 'update': if ($cart) { $newcart = ''; foreach ($_POST as $key=>$value) { if (stristr($key,'qty')) { $id = str_replace('qty','',$key); $items = ($newcart != '') ?
