Introduction

xmgr is an XY plotting tool for workstations or X-terminals using X. A few of its features are:

While xmgr has a convenient point-and-click interface, most parameter settings and operations are available through a command line interface (found in Data/Commands).

Terminology

Sets
Sets are collections of points, with optional associated values at these points. The associated values can be used to display error bars, high-low open-close plots and several other features. Sets are connected to a graph, and, by default, there are 30 sets per graph. Each set is numbered from 0 to the maximum number of sets less one. The number of points in a set is limited by the size of virtual memory and are numbered from 1 to N where N is the total number of points in the set. Operations to manipulate sets are found in Data/Set operations, and features such as line styles, symbol types, and others can be changed from Plot/Symbols.

Graphs
Graphs are the collection of data sets, tick marks, titles, etc. drawn to display the data. By default, there are 10 graphs with each graph owning 30 sets (both the number of graphs and the number of sets are adjustable via command line parameters). Operations on graphs are found in the Graphs/Graph operations popup.

There are numerous popups accessible through Graphs pulldown menu that allow the manipulation of graph parameters. Most graph operations work on what is referred to as the `current graph', marked by small filled rectangles at the corners of one graph. The 10 graphs available by default in this version of xmgr are numbered from 0 to 9.

Regions
Regions are sections of the graph defined by the interior or exterior of a polygon, or a half plane defined by a line. A region defined by a line can be above, below, to the right, or left of the line. Defining regions and operations on points inside regions are found in Data/Region operations.

Parameters
Parameters are the settings of symbols, line styles, colors, fonts, etc. used to define graphs and the display of the active sets.

Installation

To install xmgr, refer to the document INSTALL found in the xmgr distribution. This will describe the details to successfully install xmgr.
