Octave，barplot，linestyle none

Question

以下代码：

data = rand(4, 5);

figure
h4 = bar(data, "stacked", "linestyle", "none");
l4 = legend("Col1", "Col2", "Col3", "Col4", "Col5");
legend(l4, "location", "northeastoutside");

生成一个在矩形周围没有线条的图，如下面的屏幕截图所示：

但是，保存后，无论是通过菜单还是以编程方式，边框都会显示：

保存为PNG，EPS或PDF时会发生这种情况。我是否缺少一些选项来生成没有边框的框？

提前致谢，
