What are the best practices for changing the background color of a JPGraph in PHP?

To change the background color of a JPGraph in PHP, you can set the background color using the SetColor() method of the Graph object. This method takes in a color value in hexadecimal format. You can also set the background color using the SetMarginColor() method to change the color of the margin area.

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

// Set the background color of the graph
$graph->SetColor('lightblue');

// Set the background color of the margin area
$graph->SetMarginColor('lightgray');

// Add data and render the graph
// (Add your data and plot commands here)

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