What are some best practices for labeling and dividing axes when creating graphs in PHP?

When creating graphs in PHP, it is important to properly label and divide the axes to ensure clarity and readability. Best practices include clearly labeling each axis with appropriate titles, units, and scales. Dividing the axes into evenly spaced intervals can also help make the data easier to interpret. 

// Example of labeling and dividing axes in a graph using PHP
$graph = new Graph(800, 600);
$graph->SetScale("textlin");

// Set titles for the axes
$graph->xaxis->title->Set("X-axis Title");
$graph->yaxis->title->Set("Y-axis Title");

// Set units for the axes
$graph->xaxis->SetLabelFormatCallback('number_format');
$graph->yaxis->SetLabelFormatCallback('number_format');

// Divide the axes into evenly spaced intervals
$graph->xaxis->SetTextTickInterval(2);
$graph->yaxis->SetTextTickInterval(5);

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