Improved method for plotting graphs

Ching-Yuan Lee

The present invention relates, in general, to plotting graphs. More specifically, the present invention relates to an improved method for plotting graphs in real time and historical modes.

Graphs are a convenient way of pictorially representing unprocessed data. Pictorial representation facilitates deriving insights from a set of data that otherwise may appear to be a collection of figures. For example hourly power output of two turbines for the past 2 days may be easily compared when represented as bar graphs rather than when represented in a tabular format. Similarly, useful insights may be derived from the graphs illustrating the hourly success rate of calls for the past 3 days in a given telephony network.

Modern electronic systems are provided with the feature of pictorially representing the variation in a monitored parameter. The pictorial representation may include providing a visual representation such as a bar graph, a line graph, and so forth. The graphs may be drawn in a real time mode or for a historical mode. In the real time mode, the data that corresponds to a time period specified by a user is plotted in the graph. The graph is updated with the passage of time as new data arrives into the system. On the other hand, in the historical mode, all the data present in the memory of the system is plotted in the graph.

Typically, measurement systems are used for analyzing various system parameters. For example, measurement systems such as signaling analyzers are used to analyze parameters of a telephony network. The parameters may include call success or failure, call setup time, network message lengths, and so forth. Generally, the measurement systems are equipped with the feature of pictorially representing the variation of system parameters with time in the form of graphs. For example, the graphs may include pictorially representing a count of number of calls that matured successfully and a count of number of calls that failed during a time period. Further, the graphs may include pictorially representing lengths of the network messages received during a time period. Furthermore, the graphs may be displayed in the real time mode or the historical mode. In real time mode, the graph is plotted for the data received by the measurement systems during a user specified time period. For example, a graph may be plotted for the network message lengths against the time of receipt of the messages that were received during a user specified time period. In the historical mode, a graph is plotted for all the data received by the measurement systems in the past. For example, the graph may be plotted for the network message lengths against the time of receipt of the messages that were received in the past. These graphs facilitate the analysis of the system paramete...
