Hello,
I hope you can help me. The Jpgraph forum seems to be pretty
uneventful with participation.
I am trying to pass arrays through the image tag to populate my
variables for my graph.
I keep getting an error that there is no input. Do you have any suggestions?
I would greatly appreciate it! I have been trying to figure this out
for several hours.
Below is my code:
I need some help with finding a solution. For some reason my graph is
not showing up when it evident that my arrays are being passed.
When I use:
echo TEST DATA PRINT;
print_r($datay,false);
---
I keep getting the error:
Empty input data array specified for plot.

My php script is as follows:

My graph script is:
?php // content=text/plain; charset=utf-8
require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_line.php');
// Create the graph.
$graph = new Graph(1024,450,auto);
$graph-SetScale(textlin);
$graph-SetShadow();
// Slightly adjust the legend from it's default position
$graph-legend-Pos(0.03,0.5,right,center);
$graph-legend-SetFont(FF_FONT1,FS_BOLD);
//Setup X-scale
$graph-xaxis-SetTextTickInterval(10);
$graph-xaxis-SetTickLabels($datax);
//$graph-xtick_factor = 1;
$graph-xaxis-SetLabelAngle(30);
// Create the linear plot
$lineplot= new LinePlot($datay);
$p1 = new LinePlot($datay);
$p1-mark-SetType(MARK_DIAMOND);
$p1-mark-SetFillColor(blue);
$p1-mark-SetWidth(;
$p1-SetColor(blue);
$p1-SetCenter();
$p1-SetLegend(EVDO F1 Carrier);
$graph-Add($p1);
// Add the plot to the graph
$graph-Add($lineplot);
// Setup margin and titles
$graph-img-SetMargin(40,40,50,60);
$graph-title-SetMargin(10);
$graph-title-Set(Distance in MIles);
$graph-title-SetFont(FF_VERDANA,FS_BOLD,12);
// set margin color
$graph-SetMarginColor('#dcfade');
// Use built in font
$graph-title-SetFont(FF_ARIAL,FS_NORMAL,14);
$graph-ygrid-SetFill(true,'#EFEFEF@0.6','#e5e5e5@0.6');
$graph-xgrid-Show();
$graph-SetBackgroundImageMix(15);
$graph-legend-Pos(0.02,0.03,right,top);
$graph-legend-SetFont(FF_FONT1,FS_BOLD);
$graph-xaxis-title-Set(Miles);
$graph-yaxis-title-Set(MBusage);
$graph-SetAlphaBlending();
// Display the graph
$graph-Stroke();
