CSVGrapher

A graphing application desigend to provide efficient rendering independent of the number of data points. The only limiting factor is computer memory.

Usage

Until the first release, the input CSV file path is set through a constant in the Main class. The program will then read in the file, determine the bounds of the data, and then populate a quad tree with it. The interface then immediately appears. In short:

1. Set the path to the CSV file that contains the data * This file should have two columns, one for the x axis, one for the y axis
2. Run the main function in Main
3. Wait for interface to appear

Controls

• Use click and drag to pan around the graph
• Use scrolling to zoom in and out
• Use middle click to return the the default zoom level

Backend

CSVGrapher uses a quad tree data structure to boost efficiency. It only renders points that are relevant to the current zoom level. If the user wants to zoom in to expose more detail, the tree will retrieve more points from the data set, and if the user wants to zoom out to reduce the amount of detail, the tree will intelligently remove data points from the graph. Therefore, the amount of points rendered is independent of the data size and provides consistent speed regardless of input.
