Hello!

Octave 4.0 looks good. However, I am experiencing a strange thing in plotting.

The following example is the simplest case I have figured out. When I try to
plot
a equlilateral triangle, a triangle appears in the figure window. Then, to get

the right shape, I set "axis equal". After that, the triangle disappears
although
the metrics of the x-axis and y-axis are set to equal.
>> x=[0 1 1/2 0]
x =

   0.00000   1.00000   0.50000   0.00000

>> y=[0 0 sqrt(3)/2 0]
y =

   0.00000   0.00000   0.86603   0.00000

>> plot(x,y)
 I use the Japanese version of Windows 7. This also occurs on Octave 3.8.2.

Although I wrote the above report some months ago, I did not send it to you.
As I have updated my PC7s OS to Windows 10, I execute these commands and  
have the same result as that on Windows 7. 

Octave 4.0.2 on the Japanese version of Windows 10 freezes when  the 
commnads

>> x=[0 1 1/2 0]
>> y=[0 0 sqrt(3)/2 0]
>>plot(x,y)

are executed, and  the figure window is in no response.
