Embodiment Construction
[0039] The purpose and effect of the present invention will become more obvious through an optimization case of a stacked histogram of multi-dimensional housing data and the accompanying drawings.
[0040] like figure 1 As shown, the method for displaying a large-scale multi-attribute stacked histogram in a limited space in this embodiment includes the following steps:
[0041] (1) Obtain massive multi-dimensional housing data and initialize it, including standardization and weighted calculation of attributes. The specific steps are as follows:
[0042] 1-1. In the data set, let n be the number of data options, and m be the number of data indicators. Each item of data contains attributes of multiple dimensions, for example: price per unit area c 1 , area c 2 , year of construction c 3, the number of bedrooms c 4 etc., uniformly standardize the attributes of each item of data to the [0, 1] interval.
[0043] Specifically, let c j_max is the maximum value of the jth indic...
