How can one ensure consistent background color across multiple images when using JPGraph in PHP?

To ensure consistent background color across multiple images when using JPGraph in PHP, you can set the background color property for each image to the same value. This will ensure that all images have the same background color, creating a consistent look across them.

// Set the background color for all images
$graph->SetBackgroundColor('#FFFFFF');
$graph->img->SetBackgroundColor('#FFFFFF');
