Question: join in the direction fileds

> c:=-4:
> FM1:=DEplot(diff(y(x),x)=-c/x^2,y(x),x=-10..10,y=-10..10,color=red):
> FM2:=DEplot(diff(y(x),x)=x^2/c,y(x),x=-10..10,y=-10..10,color=green):
> display(FM1,FM2);

 

how can I join the direction fileds together?

i mean just like plooting the solutions of the ODEs..

 

I want to do with "linestyle"..tried, but dosent seem to work...

and i dont want to give maple specific intial conditionds to solve them and then plot them becuase i want them to change automatically since i might change the range, and i still want the lines to be continuouns..

 

Thanks
