       $this->_helper->viewRenderer->setNoRender();
   }

 

 

mas assim n posso colocar meu layout!!!

Como eu poderia colocar meu layout e colocar o gráfico???

Crie um View Helper que isso lhe ajudará você exportar os dados para a sua View!

Desculpa a demora, mas estava resolvendo outros probleminhas....

fiz o q você falow criei a seguinte classe

\application\views\helpers\Graf1.php

 

<?php
class Zend_View_Helper_Graf1 {

   public function graf1(){    
       require_once ('jpgraph/jpgraph.php');
       require_once ('jpgraph/jpgraph_bar.php');
       require_once ('jpgraph/jpgraph_line.php');
       try{         


//bar1
       $data1y = array(115, 130, 135, 130, 110, 130, 130, 150, 130, 130, 150, 120);
//bar2
       $data2y = array(180, 200, 220, 190, 170, 195, 190, 210, 200, 205, 195, 150);
//bar3
       $data3y = array(220, 230, 210, 175, 185, 195, 200, 230, 200, 195, 180, 130);
       $data4y = array(40, 45, 70, 80, 50, 75, 70, 70, 80, 75, 80, 50);
       $data5y = array(20, 20, 25, 22, 30, 25, 35, 30, 27, 25, 25, 45);
//line1
       $data6y = array(50, 58, 60, 58, 53, 58, 57, 60, 58, 58, 57, 50);
       foreach ($data6y as &$y) {
           $y -=10;
       }

// Create the graph. These two calls are always required
       $graph = new Graph(750, 320, 'auto');
       $graph->SetScale("textlin");
       $graph->SetY2Scale("lin", 0, 90);
       $graph->SetY2OrderBack(false);

       $graph->SetMargin(35, 50, 20, 5);

       $theme_class = new UniversalTheme;
       $graph->SetTheme($theme_class);

       $graph->yaxis->SetTickPositions(array(0, 50, 100, 150, 200, 250, 300, 350), array(25, 75, 125, 175, 275, 325));
       $graph->y2axis->SetTickPositions(array(30, 40, 50, 60, 70, 80, 90));

       $months = $gDateLocale->GetShortMonth();
       $months = array_merge(array_slice($months, 3, 9), array_slice($months, 0, 3));
       $graph->SetBox(false);

       $graph->ygrid->SetFill(false);
       $graph->xaxis->SetTickLabels(array('A', 'B', 'C', 'D'));
       $graph->yaxis->HideLine(false);
       $graph->yaxis->HideTicks(false, false);
// Setup month as labels on the X-axis
       $graph->xaxis->SetTickLabels($months);

// Create the bar plots
       $b1plot = new BarPlot($data1y);
       $b2plot = new BarPlot($data2y);

       $b3plot = new BarPlot($data3y);
       $b4plot = new BarPlot($data4y);
       $b5plot = new BarPlot($data5y);

       $lplot = new LinePlot($data6y);

// Create the grouped bar plot
       $gbbplot = new AccBarPlot(array($b3plot, $b4plot, $b5plot));
       $gbplot = new GroupBarPlot(array($b1plot, $b2plot, $gbbplot));

// ...and add it to the graPH
       $graph->Add($gbplot);
       $graph->AddY2($lplot);

       $b1plot->SetColor("#0000CD");
       $b1plot->SetFillColor("#0000CD");
       $b1plot->SetLegend("Cliants");

       $b2plot->SetColor("#B0C4DE");
       $b2plot->SetFillColor("#B0C4DE");
       $b2plot->SetLegend("Machines");

       $b3plot->SetColor("#8B008B");

       $b5plot->SetColor("#9370DB");
       $b5plot->SetFillColor("#9370DB");
       $b5plot->SetLegend("Single Only");

       $lplot->SetBarCenter();
       $lplot->SetColor("yellow");
       $lplot->SetLegend("Houses");
       $lplot->mark->SetType(MARK_X, '', 1.0);
       $lplot->mark->SetWeight(2);
       $lplot->mark->SetWidth(8);
       $lplot->mark->setColor("yellow");
       $lplot->mark->setFillColor("yellow");

       $graph->legend->SetFrameWeight(1);
       $graph->legend->SetColumns(6);
       $graph->legend->SetColor('#4E4E4E', '#00A78A');

       $band = new PlotBand(VERTICAL, BAND_RDIAG, 11, "max", 'khaki4');
       $band->ShowFrame(true);
       $band->SetOrder(DEPTH_BACK);
       $graph->Add($band);

       $graph->title->Set("Combineed Line and Bar plots");

// Display the graph        
       $graph->Stroke();         
       } catch (JpGraphException $e) {
           // .. do necessary cleanup
           // Send back error message
           $e->Stroke();
       }        
   }
}
?>

e na minha view coloquei a seguinte linha:

<img  src="<?php echo $this->graf1(); ?>" alt="Gráfico helper" /> 

 

E não carrega nada!!!

Não encontrei ainda o que estou fazendo de errado, alguem pode dar uma mão?

[Tiare Balbi Bonamini 2]

Eu não conheço esse plugin de grafico, mas uma coisa que você pode estar fazendo para testar e ver qual o retorno do método dentro da view, por que o que pode estar ocorrendo é a classe do gráfico não estar retornando a informação.

 

Zend_Debug::dump($this->graf1()); 

 

 

Posta o retorno do Debug depois.

Desculpa ai pessoal, resolvido o problema!!! simplesmente antes de plotar o gráfico deve ser setado o header!!!!

 

Parte do codigo q importa!!!

 

         
        header ("Content-type: image/png" ); 
        $graph->Stroke();
        //disabilita o layout
       $this->_helper->layout->disableLayout();
       ///desabilita a view
       $this->_helper->viewRenderer->setNoRender();
