Are there any best practices for displaying values on a line graph using jpgraph in PHP?

When displaying values on a line graph using jpgraph in PHP, it is important to ensure that the values are clearly visible and do not clutter the graph. One best practice is to display the values directly on the data points or at regular intervals along the line. This can be achieved by using the "value" option in the plot method of jpgraph. 

// Create a new line graph
$graph = new Graph(800, 600);

// Set up the graph properties
$graph->SetScale("textlin");
$graph->SetShadow();

// Create a line plot
$lineplot = new LinePlot($data);
$lineplot->value->Show();
$lineplot->value->SetFont(FF_ARIAL, FS_NORMAL, 12);

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

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