// Create the graph and setup the basic parameters

// Add some grace to the top so that the scale doesn't
// end exactly at the max value. 
// Since we are using integer scale the gace gets intervalled
// to adding integer values.
// For example grace 10 to 100 will add 1 to max, 101-200 adds 2
// and so on...

// Setup X-axis labels
$a = $gDateLocale->GetShortMonth();

// Setup graph title ands fonts
$graph->title->Set("Example of Y-scale callback formatting");
$graph->xaxis->title->Set("Year 2002");
// Create a bar pot
$bplot = new BarPlot($datay);

// Setup the values that are displayed on top of each bar
// Must use TTF fonts if we want text at an arbitrary angle
$bplot->value->SetFormat('$ %0.0f');
// Black color for positive values and darkred for negative values

// Finally stroke the graph
