Using the Scatter Chart, the only chart that treats the x axis as a value axis, Numbers will graph values in any of the four quadrants.
But...
Numbers will always place the x and y axes at the minimum x or y value of the range of values to be graphed, whether the minimum is set by the user or determined automatically from the data. The axes on the above graph are shapes, lines inserted by the Shapes button's menu, and placed at the zero points of the two axes. The Show axis option in both axis options menus is unchecked.
Note that while Numbers will correctly place x,y data points on the chart regardless of the order in which the pairs are listed in the table, it will connect those points in the order they are listed, leading to some interesting curves when the pairs are not sorted by their x value component.
For a more Excel-like approach to graphing, you might take a look at the open source Office applications, OpenOffice.org, LibreOffice, or NeoOffice.
For graphing functions (rather than data), see Grapher, which you'll find in the Utilities folder inside the Applications folder on your Mac.
