Problems solved by technology
Although this method creates an object in memory that is consistent with the drawing area of the screen, the amount of memory it occupies has little effect, but its main disadvantage is: because this method also requires the computer CPU to execute one n times on the memory drawing object each time When the amount of drawing data n is getting bigger and bigger, especially when all the drawing curves are displayed on the screen, the efficiency of the computer will be very low
The disadvantage of this method is: since the number of drawing data is a fixed value, in the real-time state, it cannot be set too large according to the performance of the computer, so when editing the curve on the display terminal, only the maximum number of fixed data can be seen. Plotting curves without being able to edit plotting curves beyond a fixed amount of data
That is to say, it is not possible to observe and analyze all plotted data curves in real time and as a whole on the screen

Embodiment Construction
[0048] Hereinafter, we will describe the embodiments of the present invention in detail with reference to the accompanying drawings.
[0049] Through the implementation of "Route 1": its overall flow chart is shown in Figure 1.
[0050] First, when the system is started, according to the set constants and initialization of basic data variables, these constants are the maximum index bit length, the number of branches of the "X-fork index tree", the node index bit length, the pixel resolution of the drawing area, the drawing area and the actual The scale of the drawing area. Figures 13, 14, 15, 16, and 17 show some basic data variable initialization forms.
[0051] As shown in Figure 4: In the real-time data collection part of the system, this method will make a judgment every time a collection data is obtained: if the collection data count value is less than the value of the element value of the 'zooming total level count' of the data volume upper limit array, then no Perform...

The invention relates to a curve drafting method for equipment or a software system. In the concrete, the method is as follows: when the equipment or the software system is reading in signal data externally collected at real time for a long time, or when the equipment or the software system is reading in static data with large capacity, a data index tree or numerical value tree or coding tree is synchronously established; through the data index tree or numerical value tree or coding tree, the method realizes independent dynamic or static rapid data curve drafting at a display terminal.
Description
technical field [0001] The present invention is a curve drawing method for equipment or software system, specifically, in the process of equipment or software system reading in the external long-time real-time collected signal data, or in the process of reading in large-capacity static data, Synchronously establish data index tree or numerical tree or coding tree, and use them to realize dynamic or static fast data curve drawing independently on the display terminal. Background technique [0002] The definition of editing curves here refers to: using the mouse, keyboard and other operating tools to perform operations such as zooming in, zooming out, panning, capturing, etc. on the curves on the display terminal. The definition of low computer efficiency here refers to situations such as curve drawing delays, real-time drawing curves that cannot be displayed synchronously, editing curves will be very slow, screen drawing curves will flicker, and the computer may even freeze. ...
