Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, be the schematic diagram that the present invention shows the embodiment of the method for history space-time object information, it comprises the following steps:
Step S11: the overall sequential index data of history space-time object shown in database in dynamic time sequence key map mode at the first graphical display window.As shown in Figure 2, above-mentioned dynamic time sequence key map with time coordinate (longitudinal axis) and indexed coordinates (transverse axis) for coordinate axis, wherein time coordinate axle is mutually vertical with indexed coordinates axle, plane folded by diaxon positive dirction is history space-time object sequential index region, and this sequential index region can be divided into several temporal interval along time coordinate axle, can be split into several category index intervals with different index coordinate values scope along indexed coordinates axle.In fig. 2, overall sequential index data is shown as the dynasty index entry (class in case index item) on a temporal interval and a category index interval.
Above-mentioned database comprises history space-time object sequential index data, and concrete sequential index data can be obtained by entirety and a point time domain local obtains.The corresponding different space-time object (event) of sequential index data, specifically comprises historical juncture and case index coordinate figure that space-time object (event) occurs.
Particularly, by building dynamic time sequence key map integration work district, the history space-time object sequential index data in database is carried out function to indicate description.This workspace has two-dimensional structure, organizes the access retrieval of index entry with time and indexed coordinates axle describing framework, wherein: time coordinate axle describing framework can describe the discretize integer time scale of minimum scale unit to minute magnitude; Indexed coordinates axle describing framework can describe the real number coordinate with some category index intervals.
Especially, the time coordinate axle of above-mentioned dynamic time sequence key map is with discretize integer time scale for basic measuring unit, and least unit is a minute magnitude; Dynamic time sequence key map indexed coordinates axle is basic measuring unit with real number, the interval corresponding some real number intervals of the category index on it, case index item corresponding dissimilar respectively; Each case index item being presented in dynamic time sequence key map is the two-dimensional coordinate point of a band markup information in sequential index region, and the historical time of each case index item correspondence the time showing in moment occurs in the correspondence position of time coordinate axle.
In workspace, history space-time object (event) sequential index data is described as definition discretize multivalued function y=f (x) on the x-y plane.X is that the moment occurs historical events, and y is the historical events category index coordinate figure occurred in the x moment, and y has many-valued feature, namely corresponds to same time value x and can there is several historical events category index coordinate figures.
Step S12: when being received local scale instruction and local zooming parameter by human-computer interaction interface, the selected local temporal interval on dynamic time sequence key map time coordinate axle according to described local scale instruction and local zooming parameter, obtains the local history space-time object sequential index data that selected local temporal interval range is corresponding.
Particularly, the local scale parameter received above by graphic user interface is included in local scale scope on time coordinate axle, zoom ranges center, mapping mode and scaling etc.; Local scale instruction comprises: select to close or launch category index interval in dynamic time sequence key map.
And by the dynamic time sequence key map that shows in first graphical display window of step S11 carrying out the input operation of local scale instruction and local zooming parameter.Above-mentioned input operation can be: on dynamic time sequence key map, use mouse (or touch-screen) click, dragging etc., click, be worth accordingly by a keyboard entry menu item, or the combination of aforesaid operations.Such as, on the time coordinate axle of dynamic time sequence key map, local data's zoom ranges is chosen interval as local temporal by mouse, (obtaining historical events sequential index data corresponding within the scope of this), sets partial enlargement by mouse drag or reduces parameter (zooming in or out conversion to carry out one-dimensional degree to selected scope sequential index data along time coordinate direction of principal axis) simultaneously.
Step S13: the local scale instruction obtained according to step S12 and local zooming parameter, carries out one-dimensional degree along time coordinate axle to selected local temporal interval and zooms in or out conversion, translation and/or compression are carried out to the figure of temporal interval beyond selected local temporal interval, ensure itself and one-dimensional degree zoom in or out conversion after local temporal interval do not cover generation, the local time's sequence index data obtained in step display S12 in selected local temporal interval then after zooming in or out through one-dimensional degree, to make in selected local temporal interval figure seamless combination outside local time's sequence index datagraphic and interval, form the multizone control with changed scale dynamic time sequence index pattern simultaneously showing the overall sequential index data of history space-time object and local time's sequence index data along time coordinate axle dimension with multiple association temporal interval respectively.
To obtaining the process of local data in step S12 specifically by realizing with under type in this step: directly obtain local time's sequence index data in history space-time object sequential index region; When not comprising the corresponding local time's sequence index data in category index interval of the new instruction unpack of step S12 in workspace, obtain from database and newly open the interval corresponding history space-time object local time sequence index data of category index.
This step achieves to be integrated the order-preserving of sequential index data figure outside sequential index data figure in the temporal interval of local and interval: while the local time obtained in step S12 sequence index data being shown in the local temporal interval after zooming in or out, figure outside local temporal interval is carried out or translation or compression, or compress and translation simultaneously, for the interval figure of display local temporal vacates display position, figure inside and outside local temporal interval is made to integrate one by former sequential, form the multizone control with changed scale dynamic time sequence key map simultaneously showing entire and part sequential index data along time coordinate axle dimension with multiple association temporal interval.
Particularly, as shown in Figure 6, the dynamic time sequence key map showing overall sequential index data in Fig. 2 becomes the dynamic time sequence key map with five temporal interval after conversion is integrated in the partial enlargement order-preserving of two-stage, in from top to bottom first, five temporal interval displaying ratios and Fig. 2, overall dynamics sequential key map ratio remains unchanged, the second, four temporal interval are the effect after the partial enlargement in the first interval, and the 3rd temporal interval is effect after the interval second level partial enlargement done of first order partial enlargement.
Intuitively it seems, the order preserving map conversion in dynamic time sequence key map is equivalent to the initial ensemble sequential index pattern segmentation of little rank displaying ratio " to cut off ", and inserts the amplification sequential key map of more large level displaying ratio in the position of " cutting off ".Therefore, the phenomenon that entire and part sequential key map isolates by the window edge that no longer there is " amplification of locally windowing ".
In addition, in said method, also can comprise in step s 11: by the history graphical information that the display of second graph display window is corresponding with history space-time object sequential index data; Correspondingly, can comprise after step s 13: when there being event index entry to be chosen alternately in the first graphical display window, to show in indicative mode at second graph display window history graphical information corresponding to the history space-time object local time sequence index data shown in scale transformation region (as, with conspicuous color display), history graphical information is stored in database.
As shown in Figure 3, it is the schematic diagram that the present invention shows the system embodiment of history space-time object information, its can in single window the simultaneously overall data of display timing generator key map and local data, and can history figure corresponding for sequential index entry to be presented in graphical window simultaneously.
