If I simply plot using the below code
x=0:0.1:10;
>> figure; plot(x,sin(x))
>> legend('on')
>> hold on
>> scatter(x, cos(x))
The figure looks like the below figure. The legend shows no 'line' for the first graph. It shows only circle.
How can I fix this problem?

Using:
opengl('save','software')
seems to be a solution for that problem.
See: Use Software OpenGL for Future Sessions and related topics for details.

The actual solution is to upgrade to the latest AMD video card driver.
That option was not available when I wrote this, and is now.

My Windows 10 system indicates that my currently installed Radeon 540x Series is the best driver for the machine. I didn't have this problem on my 8-year old laptop. 😕
Your solution to use opengl software is a good one but it introduces other problems like jagged edges for some lines. The need to widen line widths is annoyoing but worth mentioning so others are aware of that workaround.
