Patch vertical line along z axis
显示 更早的评论
I have been trying to use patch to draw colored lines along the axis.
The following code can correctly display the x and y axis, however it does not plot the z axis.
patch([0,1],[0,0],[0,0],'EdgeColor', 'red', 'LineWidth', 2);
patch([0,0],[0,1],[0,0],'EdgeColor', 'green', 'LineWidth', 2);
patch([0,0],[0,0],[0,1],'EdgeColor', 'blue', 'LineWidth', 2);
Given that I'm only changing what points to connect I can't understand why the first 2 instructions work, while the last one does not.

I am not sure about the issue with patch() here, but it is not the correct tool to draw lines. It is mainly used for drawing surface patches. You can use line() function
view(3)
line([0,1],[0,0],[0,0],'Color', 'r', 'LineWidth', 2);
line([0,0],[0,1],[0,0],'Color', 'g', 'LineWidth', 2);
line([0,0],[0,0],[0,1],'Color', 'b', 'LineWidth', 2);
