Chart in PHP

I'm pretty sure you can do this in pure php.  However, charting will be much faster if you can do it on the client side of things.  There are a number of libraries for this.

http://www.highcharts.com/
https://d3js.org/
http://morrisjs.github.io/morris.js/
.... and many more

You will see for both samples, you just need to output json data
http://www.chartjs.org/docs/#bar-chart-introduction

var data = {
    labels: ["January", "February", "March", "April", "May", "June", "July"],
    datasets: [
        {
            label: "My First dataset",
            fillColor: "rgba(220,220,220,0.5)",
            strokeColor: "rgba(220,220,220,0.8)",
            highlightFill: "rgba(220,220,220,0.75)",
            highlightStroke: "rgba(220,220,220,1)",
            data: [65, 59, 80, 81, 56, 55, 40]
        },
        {
            label: "My Second dataset",
            fillColor: "rgba(151,187,205,0.5)",
            strokeColor: "rgba(151,187,205,0.8)",
            highlightFill: "rgba(151,187,205,0.75)",
            highlightStroke: "rgba(151,187,205,1)",
            data: [28, 48, 40, 19, 86, 27, 90]
        }
    ]
};

You might want to consider JpGraph.

If you need some hands-on help, you might want to consider using E-E Gigs, where you can pay an expert to help you build the app.  Here's how to do the basics, using simulated data that might be found in the query results set.

// A SIMULATED RESULTS SET FROM A SQL QUERY
$results_set = array
( [ 'user' =>  'user1', 'qtde' => 60 ]
, [ 'user' =>  'user2', 'qtde' => 33 ]
, [ 'user' =>  'user3', 'qtde' => 26 ]

, [ 'user' => 'user14', 'qtde' =>  3 ]
, [ 'user' => 'user27', 'qtde' =>  1 ]

)

// COLLECT THE DATA SET FROM THE SQL RESULTS SET
$datas = $users = [];
foreach ($results_set as $row)
{
    $users[] = $row['user'];
    $datas[] = $row['qtde'];
}


// THE GRAPH TOOL
require_once ('jpgraph-3.5.0b1/src/jpgraph.php');
require_once ('jpgraph-3.5.0b1/src/jpgraph_bar.php');

// THE GRAPH SIZE AND STRUCTURE
$graph = new Graph(400,400);
$graph->SetScale("textlin");
$graph->SetTheme(new UniversalTheme);

$graph->yaxis->SetTickPositions(array(0,20,40,60,80,100), array(10,30,50,70,90));
$graph->SetBox(false);

$graph->ygrid->SetFill(false);
$graph->xaxis->SetTickLabels($users);
$graph->yaxis->HideLine(false);
$graph->yaxis->HideTicks(false,false);

// ADD THE DATA TO THE GRAPH
$barplot = new BarPlot($datas);
$graph->Add($barplot);
$barplot->SetColor("white");
$barplot->SetFillColor("red");
$graph->title->Set("Example Bar Plot");

// DISPLAY THE GRAPH
$graph->Stroke();

Good Morning,

Has helped a lot, I'll do here, then I say if it worked.

Thank you.

greetings  Alex, , The way that a PHP and javascript CHART is made depends on the Chart you need to build. I looked at the image in your   Capturar.PNG  that you have here, and at the very Top of that Image , you have columns labeled A to M , can you tell us what code you used to make that chart, and what the columns labeled A to M, are used for?
Also if you tell us about what the things to need to chart, like "Prices", "Car Sales", "Voting Results" or "Sports Scores", then we can tell you what we might use to chart that type of value in a vertical Chart.

The more you can say about your chart, the more we can tell you about the ways to do it.

Hello,

It is a portal where you will be told the number of alarms assigned to each analyst.

The query is quite simple.

The select is attached.

Thank you.
