本文介绍了一种在Matlab中使用特定代码精确控制图表上文本位置的方法。通过更改坐标单位并设置文本属性，可以实现对图表元素的精细调整。示例代码展示了如何在不同位置放置标记文本。

Sample code:
old_units = get(gca,'units');
set(gca,'units','inches');
ax_pos = get(gca,'position');
ax_width_inches = ax_pos(3);
set(gca,'units',old_units);
% text(ax_width_inches + 1.0, -0.3,
'benchmark','units','inches',
'FontWeight','normal','FontSize',myfontsize,'FontName','Times New
Roman');
text(ax_width_inches - 1.55, -0.3, 'f_L','units','inches',
'FontWeight','normal','FontSize',myfontsize,'FontName','Times New
Roman','fontangle','italic');
text(ax_width_inches + 0.15, -0.3, 'f_C','units','inches',
'FontWeight','normal','FontSize',myfontsize,'FontName','Times New
Roman','fontangle','italic');
text(ax_width_inches + 1.65, -0.3, 'f_H','units','inches',
'FontWeight','normal','FontSize',myfontsize,'FontName','Times New
Roman','fontangle','italic');
