...ins along both the X and Y axes. I have looked everywhere I can think for information. Can anyone give me any suggestions? Is there a single command that generates it or do I have to generate a regular scatterplot then add the additional plots in the margins? Thanks in advance for your help. Neil Desnoyers

...is that it's the "proper extent of the bar". Is that the maximum value? Or is it the labels for my vertical axis, since the axes seem to be switched for this command? Is there a better/different command I should be using for barcharts (i.e. barplot)? Thanks for your assistance. Neil Desnoyers

Hi Andi, This series of patches updates paravirt_ops in various ways. Some of the changes are plain cleanups and improvements, and some add some interfaces necessary for Xen. The brief overview: add-MAINTAINERS.patch - obvious remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed paravirt-nop.patch - mark nop operations consistently paravirt-pte-accessors.patch - operations to pack/unpack
