Abstract

The invention discloses a method for realizing an interactive time axis with a thumbnail based on LiveChart. The method comprises steps of utilizing WPF basic technology to access a data source and acquire data; sorting the data into a data set format; building a ViewModel newly; setting ChartValues to provide a bindable data source; setting two starting and ending time point attributes corresponding to a time period when the main graph needs to display data, newly establishing a WPF window, introducing Cartesian Chart, binding Chart Values, and setting a corresponding data display interval for the Cartesian Chart. The interactive time axis application can be quickly generated, when the time axis is dragged, the first chart can roll left and right along with the rolling wheel, and when themiddle sliding wheel of the mouse is rolled, the display range can be dynamically zoomed.

Description

technical field [0001] The invention relates to the technical field of Net WPF development, in particular to a method for realizing an interactive time axis with thumbnails based on LiveChart. Background technique [0002] Data visualization is a scientific and technological research on the visual representation of data, mainly by means of graphical means to convey and communicate information clearly and effectively. [0003] At present, the visualization of big data is not only satisfied with the simple static display of data, but more and more inclined to the visualization that can be interactively operated. The time axis is a very efficient visual expression method, which can not only display the data intuitively Or major events, etc., can also extend the data display within a limited fixed screen range through mouse dragging, scroll wheel and other operations. [0004] LiveCharts is a visual chart library of Microsoft WPF development platform, which can realize many dat...
