Ver5からデフォルトのフォントサイズが変更になっています。

それ以前のフォントサイズに戻すには下記のパッチを当てる必要があります。

// The following lines are used for EC3.8 upgrade test 12/4/2007
chart.setAdjustFont(false);
chart.gethXAxis().gethLabel().setFont(new Font(“Arial”, Font.PLAIN, 9));
chart.gethYAxis().gethLabel().setFont(new Font(“Arial”, Font.PLAIN, 9));
chart.gethLegend().gethText().setFont(new Font(“Arial”, Font.PLAIN, 9));
// End of test
