在线版本和 2019a 版本的 Matlab 结果不同

Question

我堆叠了条形码，我希望看到低于零的负值。当我使用 MATLAB 在线版本时，我可以获得我想要的结果，但是当我在计算机上执行它时，它不区分正值和负值。 我正在使用 MATLAB 2019a。

Answer 1

在 MATLAB Release Notes for R2019b您可以阅读:

The bar and barh functions have these improvements:

• Stacked groups of bars display negative bars below zero, rather than overlapping the bars.

也就是说，这是 R2019b 中引入的更改(MATLAB Online 始终使用最新版本)。因此，如果您想在桌面上重新创建这些图形，则必须升级 MATLAB 版本。
