Optionally, v ═ u.

S400, traversing the twin node list N, and for any N_iIf T is_istart＝min(T_istart) Then N will be_iDrawn in grid area (x)₀，y₀) At position (x) where₀＝0，y₀＝C₀*v，C₀Rendering the grid area corresponding to x before Ni₀C0 is initialized to 0; increase C0 by 1. That is, the start time equals min (T) for the first event_istart) Is plotted at the (0,0) position of the grid area, i.e. the coordinate origin, for a subsequent event start time equal to min (T)_istart) The abscissa of the M nodes is equal to 0, and the ordinate of the M nodes is V, 2V, …, M × V in sequence, as shown in fig. 1, where the event start time is equal to the node of day 3, month 2. I.e. time equal to min (T) since the first event was found_istart) Is started, the start time of each event found is equal to min (T)_istart) The node counter C0 is incremented by 1.

S500, if T_istart>min(T_istart) Then N will be_iPlotting at (x, y) locations of the grid area, where x ═ u [ T ]_iend-min(T_istart)]，y＝C_x*v，C_xIs N_iThe node counter value corresponding to x was previously plotted in the grid area, with Cx initialized to 0; cx is increased by 1. That is, the start time is greater than min (T) for the first event_istart) Is plotted in the grid area of (u x T)_iend-min(T_istart)]0) position, start time for subsequent eventIs equal to min (T)_istart) All of the M nodes of (1) have the abscissa of u x T_iend-min(T_istart)]The ordinate values are V, 2V, …, M x V in order, as shown in fig. 1 for nodes with event start times greater than 3 months and 2 days. I.e. the time is greater than min (T) from finding the first event_istart) The start time of each event found is greater than min (T)_istart) The node counter value Cx is increased by 1.

Through S400 and S500, each node in the twin node list N can be drawn on the grid area of the display area according to the event start time and the event end time, and inevitably, the leading event and the following event corresponding to each node are also drawn on the grid area, thereby forming visualized information, so that the user can intuitively and clearly know the progress of the event.

In the embodiment of the invention, the node N_iThe display area can be drawn as a preset shape, such as a circle, a square, a triangle, etc. Preferably, drawn as a circle. Node N_iRadius R of_iDetermined according to the number m of leading events and the number n of following events, i.e. R_i＝f(m,n)。

Preferably, the radius R_iPositively correlated with m + n.

In another exemplary embodiment, it is preferred if R₀*(m+n)^1/2>min (v/2, u/2), then R_iMin (v/2, u/2), otherwise, R_i＝R₀*(m+n)^1/2And min (v/2, u/2) is the upper limit of the radius of the set circle. In another exemplary embodiment, it is preferred if R₀*(m+n)^1/2>min (v/3, u/3), then R_iMin (v/3, u/3), otherwise, R_i＝R₀*(m+n)^1/2And min (v/3, u/3) is the upper limit of the radius of the set circle.

In the embodiment of the invention, the radius of the node is positively correlated with the number and the positive of the leading events and the subsequent events, and for R_iLarger nodes are generally regarded as more important key nodes, and therefore can be more intuitively highlighted. Further, the maximum radius of the node is limited to the upper limit of the set radius, and therefore R can be avoided_iInfinite and easily overlay neighboring nodes.

Further, in another embodiment of the present invention, node N_iIn which display area different drawing colors are drawn. Similarly, the depth of the drawing color is also determined in accordance with m and m. Preferably, the depth of the drawing color is positively correlated with m + n.

I.e. a node with a radius equal to min (v/3, u/3), is rendered in a different rendering color in the display area 4. The remaining nodes, which are less than min (v/3, u/3), will be rendered in the same color. The color depth can be set in a grading way and can be set according to the needs of a user in a self-defining way, for example, when m + n is 10, purple can be drawn, when 6 < (m + n) < 10, red can be drawn, and the like.

In the embodiment of the invention, the nodes with the radius equal to min (v/3, u/3) are drawn in different drawing colors in the display area, and the larger the "actual value (m + n)" is, the darker the drawing color is, so that the intuitive comparison can be performed through the colors under the condition that the radius of the nodes is the same.

Further, in the embodiment of the present invention, the node N_iAlso included are node description texts, e.g., the person in charge of the node, a brief textual description of the event. When the user input is positioned at node N_iWhen above, for example, when the user's mouse or the user's finger (in the case where the display device is a touch panel)Placed at node N_iWhen the node description text is displayed to the user, the node description text is displayed to the user in the form of a floating window.

In another embodiment of the present invention, the system may further comprise: and (5) inquiring a box. When a user inputs a keyword, such as a name of a project person in charge, to be queried in the query box, the processor searches in the node description text according to the keyword, and displays a searched result on a corresponding node, for example, the corresponding node is displayed in a color changing, enlarging or flashing manner, and at the moment, the user can see related information by clicking the corresponding node. By setting the query box, the user can query the information needing to be known in a targeted manner.

Further, in the embodiment of the present invention, when the user clicks (or may perform other operations) a node in the grid area, such as node N shown in fig. 2_iIn the grid area and node N_iThe corresponding list of leading events P and the list of following events Q will be presented to the user in a wired manner, as shown in FIG. 2, node N_iThe leading events A1-A4 and the following event A5 are respectively connected with the node N through connecting lines with arrows_iPresentation of the manner of connection, leading event and node N_iIn the direction of the arrow between points to N by the leading event_i.
