Google Charts

Hello Experts, I've spent countless nights trying to figure out a solution to this probably simple problem I have. Maybe someone can show me what I'm doing wrong or a simpler way to accomplish what im trying to succeed. What I have is 2 pages one PHP page that pulls the sum of all transactions per month and sends that information to the Javascript page when then takes that data as a JSON object and renders it inside the google charts array My php example is below here. if someone can look through it and let me know if im doing something wrong please let me know I need all the help i can get!!

$view       = filter_input(INPUT_POST, 'view');
$log        = new diary();
if (!$view) {
    return false;
} else {
    if ($view == 'MonthlyProfits') 
        {
        $year = filter_input(INPUT_POST, 'year');
        $amount = array();
        for ($i=0; $i < 11; $i++)
            {
            $query = "SELECT sum(transaction_amount) as amount FROM finanical_transactions WHERE (transaction_date BETWEEN '$year-$i-1' AND  '$year-$i-31' AND transaction_type_code = '12000')";
            $FetchProfits = new explore('accounting');
            $profits = $FetchProfits->fetch($query);
            $amount = new stdClass();
            $amount->type    = 'string';
            $amount->month   = date("M", $i);
            $amount->amount  = $profits[$i]['amount'];
            }
       $j_son = json_encode($amount);
       $log->problem($j_son);
       echo $j_son;
       return false;
            
        }
}

Once the page loads it takes that echod $j_son var and renders it through the arrayToDataTable() function google gives us. The Code is below this line.

function ProfitChart(year) {
    connect_ajax();
    xmlhttp.onreadystatechange = function() {
	if (xmlhttp.readyState===4 && xmlhttp.status===200)
            {
            console.log(JSON.parse(xmlhttp.responseText));
            var data = new google.visualization.arrayToDataTable(JSON.parse(xmlhttp.responseText));    
            var options = {
                    title:'Qtr Profit Loss',
                    vAxis: {title: 'Year', titleTextStyle: {color: 'gold'}}
                    };
            var chart = new google.visualization.ColumnChart(document.getElementById('profitlossbar'));
                chart.draw(data, options);
            }
    };
var file = "http://" + u + "/members/Sales";     
var values = "view=MonthlyProfits&year=" + year;
xmlhttp.open("POST", file, true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(values);
}

The Final result should be a query of each month sumed up and displayed in a column chart. Thanks for the help experts!!

Don't know what's the problem with your code, but if all you want is to display graphs with php, the easiest library I know of is JpGraph: http://jpgraph.net/

HTH,
Dan
Hey Chris, can you please show us the data?  We already know the code doesn't work, so looking at that is not really helpful.  If we can see the inputs you have and the outputs you need we can usually help bridge the gap.

Also, I second the recommendation of JpGraph.  Great library!

I've tried jpGraphs and i keep getting a blank image also I don't like using the GD Library im not fimuliar with that yet but to answer your question..

$FetchProfits = new explore('accounting'); //querys the database
$profits = $FetchProfits->fetch($query); // Fetches the results and stores them
$amount = new stdClass();
$amount->type    = 'string'; // This is the type of variable I am out putting
$amount->month   = date("M", $i); // This Sets the Month that we are fetching
$amount->amount  = $profits[$i]['amount']; // This would display the amount profit for the month


The Result would be a Column Bar Chart Displaying Each Month and that would be displayed horizontally below. I think my main problem is setting up the array cause when I type the numbers in manually it works fine. maybe if someone knows a example of how to dynamically get info from the database and send it to JavaScript using j son and send it to Google charts in the format that they need
So Here is a new route im trying to do but now i get a different error Message Saying "Table Has No Columns" Code is Posted Below.

function ProfitChart2() {
    google.load('visualization', '1', {packages:['corechart'], callback: loadData}); 
}
            
function drawChart(json) {
    var data = new google.visualization.DataTable(json);
    var options = {
        vAxis: {minValue: 0}
    };
    var chart = new google.visualization.AreaChart(document.getElementById('profitlossbar'));
    chart.draw(data, options);
}

function loadData() {
    connect_ajax();
    //var request=new XMLHttpRequest();
        xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                drawChart(xmlhttp.responseText);
                //xmlhttp.responseText;
        }
    };
    var file = "http://" + u + "/members/Sales";     
    var values = "view=MonthlyProfits";
        xmlhttp.open("POST", file, true);
        xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xmlhttp.send(values);
}
