The diagram illustrates the designing of the ground floor of a particular building since 1958 to present. The using purpose has been changed over time. The draws showed that there is an inverse relationship between the purpose of using and the numbers of rooms in each plan. Therefore, the numbers of rooms gradually decrease through the years when the using purpose had changed.
