What are the potential reasons for the x-values not being displayed correctly in a JPGraph line graph?

The x-values may not be displayed correctly in a JPGraph line graph due to incorrect formatting or data type conversion issues. To solve this problem, ensure that the x-values are properly formatted as strings or integers before passing them to the graphing function. Additionally, check for any errors in the data retrieval process that may be affecting the x-values. 

// Sample code snippet to ensure x-values are properly formatted before plotting the graph
$xValues = array("Jan", "Feb", "Mar", "Apr", "May");
$yValues = array(10, 20, 15, 30, 25);

// Create a new graph
$graph = new Graph(400, 300);
$graph->SetScale("textlin");

// Create a line plot
$lineplot = new LinePlot($yValues);
$lineplot->SetFillColor('lightblue');

// Assign x-values to the line plot
$lineplot->SetXData($xValues);

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

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