The below will draw the same chart as the `basic` example, except with both the x and y axes turned on.

|
In this case, both the x and y axis ticks are generated automatically, the x and y ranges are established automatically,
|
|
the canvas "box" is adjusted to fit the space the axes occupy so as not to clip.
|
|
Additionally, it shows how you can use the "Descending" property of continuous ranges to change the ordering of
|
|
how values (including ticks) are drawn.
