# XYTable

XYTable is a class which maintains a list of X-Y values. These can be plotted in the VarWatch SICS client by configuring it with a special command. Before you may use an XYTable object it had to be installed into the system by you friendly SICS administrator. For this documentation it is assumed that this has happened and a XYTable object is available in the system under the name ixi. How to configure a XYTable object can be learnt from the SICS managers documentation.

Interaction with the XYTable object happens through the following commands:

ixi clear
  clears all entries in the x-y table.
ixi list
  lists the entries in the x-y table on the screen.
ixi write filename
  writes the x-y list to the disk file filename. This file resides on the machine running the SICS server.
ixi uuget
  sends the x-y list in an uuencoded format. This is the command to give to the VarWatch SICS client in order to make it display the x-y list.
ixi add x y
  creates a new x-y list entry with the values x and y.
