A system and method for processing a stored original data set for subsequent display on a user interface of a computer, the original data set having multiple dimensions and a number of original data points greater than the number of pixels available on the user interface for displaying a representative pixel value for the data value of each of the original data points. The system comprises a data reduction module for reducing the original data set to produce a reduced data set having a number of reduced data points less than the number of original data points. The number of reduced data points is based on a received query parameter including at least one of available memory of the computer, a range of a continuous dimension of the multiple dimensions, and a level of detail for at least one dimension other than the continuous dimension. The system includes a data resizing module for dynamically resizing the received reduced data set to produce a resized data set suitable for use in generating a display of pixels appropriate to the number of available pixels. The data resizing module is configured for summing or otherwise combining the individual data values of selected adjacent ones of the reduced data points in the reduced data set and assigning the combined value to a respective data value of a resized data point in the resized data set. The system also has a pixel module configured for using a predefined colour scale for assigning a unique colour as the representative pixel value of the respective data value of a resized data point included in the display of pixels, such that the colour scale is configured for defining a plurality of the unique colours to different data values of the individual resized data points.
