How can variables be displayed using jpgraph in PHP?

To display variables using jpgraph in PHP, you can create a graph object, add a plot to the graph, and then use the SetData method to pass in the variables you want to display. Finally, call the Stroke method to output the graph.

<?php
// Include the jpgraph library
require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_line.php');

// Create a new graph object
$graph = new Graph(400,300);

// Set up the plot
$lineplot = new LinePlot($data);

// Add the plot to the graph
$graph->Add($lineplot);

// Set the titles
$graph->title->Set("Variable Display");
$graph->xaxis->title->Set("X-axis");
$graph->yaxis->title->Set("Y-axis");

// Display the graph
$graph->Stroke();
?>
