Respuesta: jpgraph Curvas y Barras Hola Lair, te agradezco mucho tu respuesta, pero la idea del Grafico en con curvas como las que nos muestra http://doc.async.com.br/jpgraph/html...splineex1.html esta es la que usa interpolaciones.
Mira haciendo pruebas llegue a esto pero todavia me falta dejar bien alineadas la barras. Código PHP: <?php include "jpgraph.php"; include "jpgraph_line.php"; include "jpgraph_scatter.php"; include "jpgraph_regstat.php"; include ( "jpgraph_bar.php" ); // Original data points $xdata = array(195,196,197,198,199,200,201,202,203,204,205,206,207,208,209,210,211); $ydata = array(0,0,0,0,0,0,0.0001,0.0044,0.0540,0.2420, 0.3989, 0.2420,0.0540, 0.0044,0.0001,0,0 ); // Get the interpolated values by creating // a new Spline object. $spline = new Spline($xdata,$ydata); // For the new data set we want 40 points to // get a smooth curve. list($newx,$newy) = $spline->Get(100); $linea=0; $ynew= array(); foreach ($newx as $key => $value) { // echo "Clave: $key; Valor: $value<br />\n"; if(floor($value) == @$xdata[$linea]) { $ynew[$key]= $ydata[$linea]; $linea++; } else { $ynew[$key]=''; } } // Create the graph $g = new Graph(500,400); $g->SetMargin(30,20,40,30); $g->title->Set("Natural cubic splines"); $g->title->SetFont(FF_ARIAL,FS_NORMAL,12); $g->subtitle->Set('(Control points shown in red)'); $g->subtitle->SetColor('darkred'); $g->SetMarginColor('lightblue'); $g->img->SetImgFormat('jpeg'); // Create a bar pot $bplot = new BarPlot ($ynew,$newx); $bplot -> SetFillColor ( "orange" ); //$g->img->SetAntiAliasing(); // We need a linlin scale since we provide both // x and y coordinates for the data points. $g->SetScale('linlin'); // We want 1 decimal for the X-label //$g->xaxis->SetLabelFormat('%1.1f'); //$g -> xaxis -> SetTickLabels ( $newx ); // We use a scatterplot to illustrate the original // contro points. $splot = new ScatterPlot($ydata,$xdata); // $splot->mark->SetFillColor('[email protected]'); $splot->mark->SetColor('[email protected]'); // And a line plot to stroke the smooth curve we got // from the original control points $lplot = new LinePlot($newy,$newx); $lplot->SetColor('navy'); // Add the plots to the graph and stroke $g->Add($bplot); $g->Add($lplot); $g->Add($splot); $g->Stroke(); ?> Espero me puedas ayudar.
