What are some common issues or challenges when setting a maximum and minimum value for the y-axis in JPGraph?

One common issue when setting a maximum and minimum value for the y-axis in JPGraph is ensuring that the range adequately represents the data without cutting off important information. One way to solve this is by dynamically calculating the maximum and minimum values based on the data being plotted. 

// Calculate dynamic y-axis range
$maxValue = max($data);
$minValue = min($data);
$range = $maxValue - $minValue;

// Set y-axis range
$graph->SetScale('textlin', $minValue - 0.1*$range, $maxValue + 0.1*$range);
