title('正弦波');
xlabel('时间');
ylabel('振幅');
grid on;

这样，用户不仅可以快速生成图表，还可以使其符合特定的格式和风格要求。这种高度的灵活性使得MATLAB在科学研究、工程应用和教育等领域得到了广泛应用。

三、与其他工具的良好集成

MATLAB不仅自身功能强大，还可以与其他工具无缝集成。例如，可以将MATLAB的图表嵌入到Microsoft Word、Excel等办公软件中，或导出为PDF、JPEG等格式供其他软件使用。此外，MATLAB还支持与数据库、其他编程语言（如Python、R）的数据交换，使得数据处理和可视化过程更加高效和便捷。

四、用户友好的界面

MATLAB提供了直观的用户界面，方便用户进行数据可视化操作。通过“Figure”窗口，用户可以交互式地编辑图形，调整图形属性，添加注释等。MATLAB还提供了丰富的帮助文档和示例代码，帮助用户快速上手并解决实际问题。

五、应用案例

MATLAB的数据可视化功能在多个领域有着广泛的应用。例如：
