八度:如何在drawRect中更改线条的颜色和宽度 [英] Octave : How to change line color and width in drawRect

问题描述

:-)大家.

是否可以在八度中更改函数 drawRect 的线条颜色和宽度?

Is there any way to change the line color and width of function drawRect in Octave ?

根据其引用，没有要设置的属性值对此功能.

According to its reference, there's no property-value pair to set in this function.

谢谢.

推荐答案

drawRect函数不接受属性值对，但是会返回图形句柄，您可以在其中设置任何属性:

The drawRect function does not accept a property-value pair, but it does return a graphics handle from where you can set any property:

r = drawRect (x, y, w, h);
set (r, "color", [1 0 0]); # set to red (RGB triplets)
set (r, "linewidth", 5);

使用get (r)查看所有属性的列表，或阅读手册部分

Use get (r) to see a list of all properties, or read the manual section graphics object properties.
