Description
Technical Field
The invention relates to the field of data processing, in particular to a method and a device for displaying data by using graphs.
Background
in the prior art, when data is analyzed, in order to intuitively understand the rule and trend of the data changing with time as a whole, each data to be displayed is usually displayed according to the time dimension thereof by using some charts (such as a graph, a histogram, and the like). However, when one or more pieces of data in a group of data to be displayed have a large difference (e.g., a numerical difference) from other data, it is difficult to see the variation trend of other data. In the prior art, the data with large differences are generally considered to be abnormal data, and the abnormal data are generally discarded in the process of displaying the data.
However, when a group of data changing according to time is displayed, if abnormal data with large difference is not discarded, it is difficult to see the changing trend of other data, for example, the value of data 6 shown in fig. 1 is much larger than that of other data, and the changing trend of other data cannot be known from the graph; if the data with larger difference is discarded (e.g. the value of data 4 in the figure is zero), it is difficult to reflect the data change rule and trend at the time point or in the time period of discarding, as shown in fig. 2.
Aiming at the technical problem that the trend of the data to be displayed changing along with the time cannot be accurately displayed due to the fact that one or more data in the data to be displayed have larger difference with other data in the prior art, an effective solution is not provided at present.
