Hi,

I have set the width as 850.

PHP Code:

$graph = new Graph(850,250,"auto");

$graph->SetScale("textlin",0,$max); 

How can I set the width as 250px and plot the values of array limit to 125px.

I want the width and height as 850 and 250. but the graph drawn should not cover the 250 spacing it should plot only till 125px.

How can I adjust the width and scaling to it

you will have to post the Graph class source or a link to the Graph class documentation before we can help you any further

Hi,

I want the graph to look lik this.
The graph is attached is implemented in gdlib.
I am trying to implement the same in JPgraph.

I want to set the graph width manually.Please help me how can I proceed with it

PHP Code:

include ("/var/www/jpgraph-1.19/jpgraph.php");
include ("/var/www/jpgraph-1.19/jpgraph_line.php");

$ydata = array(11,280,57,10,7,100,200,54,100,5,1,9,13,5,7,45,11,3,8,12,45,53,56,11,34,57,10,7,34,23,54,100,5,1,9,13,5,7,45,11,3,8,12,45,53,56,11,34,57,10,7,34,23,54,100,5,1,9,13,5,7,45,11,3,8,12,45,53,56,11,34,57,10,7,34,23,54,100,5,1,9,13,5,7,45,11,3,8,12,45,53,56,11,34,57,10,7,34,23,54,10,10,10,10,10,10,10,45,11,3,8,12,45,53,56,11,34,57,10,7,34,23,54,100,5,1,9,13,5,7,45,11,3,8,12,45,53,56,45,53,56,11,34,57,10,7,34,200,5);
$max=max($ydata);
$graph = new Graph(620,200,"auto");
$graph->SetScale("textlin",0,$max);
$graph->img->SetMargin(40,40,40,40);
$lineplot = new LinePlot($ydata);
$lineplot->SetColor("red");
$graph->xaxis-> title->Set("Time(hr)--------->" );
$graph->yaxis-> title->Set("%---------------->" );

$graph->title->SetFont(FF_FONT1,FS_BOLD);

$graph->SetMarginColor("red");
$graph->yaxis->title->SetFont(FF_FONT1,FS_BOLD);
$graph->xaxis->title->SetFont(FF_FONT1,FS_BOLD);
$lineplot->SetLegend("Value Up");
$graph->legend->SetLayout(LEGEND_HOR);
$graph->legend->Pos(.5,.9,"center","right");
$graph->legend->SetFillColor("lemonchiffon2:1.3");
$graph->yaxis->SetColor("red","black");
$graph->xaxis->SetColor("red","black");
$graph->xaxis->SetTickLabels($hours);
$graph->xaxis->SetTextLabelInterval(2);
$graph->xaxis->SetFont(FF_FONT1,FS_BOLD);
$graph->yaxis->SetFont(FF_FONT1,FS_BOLD);
$graph->xaxis->SetTextTickInterval(6);
$graph->yaxis->SetTextLabelInterval(2);
$graph->yaxis->HideFirstLastLabel();
$graph->SetBackgroundGradient('lemonchiffon','white',GRAD_MIDHOR,BGRAD_PLOT);
$graph->SetMarginColor('lemonchiffon2:1.3');
$graph->ygrid->SetColor('orange');
ddText($txt);

$graph->Add($lineplot);
//$graph->Add($lineplot2);
$graph->Stroke();

Do you mean settings the Margins?

PHP Code:

$graph = new Graph(850, 250) ;

$graph->SetMargin(x1, y1, x2, y2) ; 

Untested. Not totally sure on this.
Let us know how you get on...

SetMargin is to set the area.

But I want the graph to be plotted within the specified area.

Supppose width is 250px I want the width to plot with in 125px but the width should be 250px

I'd recommend asking this question in the JPGraph Help Forum.
