I want to visualize graph of y = k/x (k > 0). Assume k = 10, for this example. I referred to basic command, but it's not giving me the graph as I want.
I want same scale on both axes (i.e. same length for y and x axes for 1 unit). Generally the y axis is automatically scaled, so that x pixels represent different units on y and x axes. I don't want that. I also want to have grid lines of unit squares.
The documentation for showing graphics has lots of options. In your case, aspect_ratio=1 will give the same scale, and gridlines and similar options control grid lines.
Actually, because k/x has an asymptote, if you really want the same scale on both axes, you'll probably want to cut off the vertical axis fairly low down. Try this example:
k = 10
plot(k/x,x,0,10,gridlines=True,aspect_ratio=1, ymax=10)
For even more control of those grid lines, read the documentation for this (search for) [xlist,ylist]: and you can pass in whatever lines you want.
k = 10
plot(k/x,x,0,10,aspect_ratio=1, ymax=10, gridlines=[range(10),range(10)])
Or you can make the ticks different as well.
Thanks, aspect ratio helps! But still the gridlines are at a distance of 2 units. I wanted at a distance of 1 unit. How do I to that?
