Good afternoon, I have the following query:

SELECT 
 DATE(o.data_fechamento) AS Data,
 u.nome   AS Pessoa,
 COUNT(*) AS Total
FROM
    ocorrencias AS o
        LEFT JOIN sistemas AS a ON a.sis_id = o.sistema
        LEFT JOIN localizacao AS l ON l.loc_id = o.local
        LEFT JOIN instituicao AS i ON i.inst_cod = o.instituicao
        LEFT JOIN usuarios AS u ON u.user_id = o.operador
        LEFT JOIN usuarios AS ua ON ua.user_id = o.aberto_por
        LEFT JOIN 'status' AS s ON s.stat_id = o.status
        LEFT JOIN status_categ AS stc ON stc.stc_cod = s.stat_cat
        LEFT JOIN problemas AS p ON p.prob_id = o.problema
        LEFT JOIN sla_solucao AS sls ON sls.slas_cod = p.prob_sla
        LEFT JOIN prioridades AS pr ON pr.prior_cod = l.loc_prior
        LEFT JOIN sla_solucao AS slr ON slr.slas_cod = pr.prior_sla
        LEFT JOIN script_solution AS sol ON sol.script_cod = o.oco_script_sol
        LEFT JOIN prior_atend AS prioridade_atendimento ON prioridade_atendimento.pr_cod = o.oco_prior
     WHERE
          o.status IN (4)
          AND MONTH( o.data_fechamento) = MONTH(NOW())
          AND YEAR( o.data_fechamento) = YEAR(NOW())
          GROUP BY  DATE(o.data_fechamento),u.nome
          ORDER BY  o.data_fechamento ASC

It returns something like:

 Data       Pessoa  Total
2017-04-01  MARCOS  3
2017-04-01  PAULO   5
2017-04-02  MARCOS  7
2017-04-02  PAULO   3
2017-04-03  MARCOS  8
2017-04-03  PAULO   9
2017-04-04  MARCOS  4
2017-04-04  PAULO   10

I would like to apply it with the returns automatically in a while php showing the result as the example of the image I attached below in a google line chart.

How could you be doing this?

Calculate minimum number of permutations to sort how to read return variables using json curl and php

When I'm going to create graphs with data in the database, I like to use google.visualization.arrayToDataTable . I build the data in Controller and step into View only what I need.

In the Controller, I create a function to mount this data:

public static List<object[]> Grafico(ICollection<ValoresInvestimento> lista)
{    
    List<object[]> data = new List<object[]>();

    data.Add(new[] { "Label", "Líquido", "Bruto"});

    foreach (var valores in lista)
    {
        data.Add(new object[] { valores.Mes.ToString1800("MMM/yy"), valores.ValorLiquido, valores.ValorBruto });
    }
    return data;
}

Within the list I pass as a parameter is the query with the search. The return of data is array of array :

Array [ Array[3], Array[3], Array[3] ]

Within each Array[3] we have the following structure:

0: Array[3]
0: "Label"
1: "Liquido"
2: "Bruto"

1: Array[3]
0: "jan/17"
1: "208480.03"
2: "260600.04"

2: Array[3]
0: "fev/17"
1: "777708"
2: "972135"

In the View, I make a call to fetch the data and draw the chart:

$.ajax({
    type: "POST",
    async: false,
    url: '@Url.Action("BuscaRelatorio", "RelatorioInvestimento")',
        contentType: 'application/json',
        dataType: "json",
        data: JSON.stringify({ grid: grid }),
        success: function (data)
        {
            Grafico(data.Retorno.Grafico);          
        }       
    });
}

The BuscaRelatorio function, which is passed in ajax, has the following return:

return Json(new RetornoAjax
{
    Retorno = new
    {                  
        Grafico = Grafico(lista)
    }
});

Inside this return, I call the function Grafico to draw:

function Grafico(data) {

    var dadosGrafico = google.visualization.arrayToDataTable(data);

    var options = {                
            legend: { position: 'right', textStyle: { color: 'black' }, fontSize: 12 },
            width: "100%",
            height: 400,                
            vAxis: {
                title: "Valor",
                titleTextStyle: {
                    color: '#000',
                    bold: true,
                    italic: false
                },                   
            },
            chartArea: {
                height: "80%",
            },
            hAxis: {
                title: "Meses",
                 titleTextStyle: {
                     color: '#000',
                     bold: true,
                     italic: false
                 },
                 textStyle: { color: 'black' }
             },
            fontSize: 11,                
        };

    var chart = new google.visualization.LineChart(document.getElementById('grafico'));
    chart.draw(dadosGrafico, options);

    function resizeCharts() {
        // redraw charts, dashboards, etc here
        chart.draw(dadosGrafico, options);
    }

    $(window).resize(resizeCharts);
};

There are other ways to make this chart, I'd rather bring the controller graphic ready. I hope this code in C # helps you understand the structure, so you can do it in PHP.
