Embodiment
[0019] a) Determine the position of the center point (X0, Y0) according to the height (Height) and width (Width) of the window, X0=UserControl.Width / 2, Y0=UserControl.Height / 2;
[0020] b) Set the scale range (PMax (maximum indication value), PMin (minimum indication value)) according to the maximum and minimum values of the input measurement data, and determine the number of scales, the total number of scales = PBigNum (number of large scales) * PSmallNum ( Small scale number), calculate the interval between two adjacent scales DisNum=(PMax-PMin)\PBigNum;
[0021] c) Draw the outer frame of the dial according to the center point obtained in steps a) and b) and the size of the display window. In this embodiment, a circular outer frame is selected. When selecting the shape of the outer frame, each outer frame is given a Attribute value, 0, means circle, 1, means square, the assignment of this attribute is the enumeration variable Type_Num:

The invention provides a method for displaying measured data by simulating an indicating instrument. The method comprises the following steps: (a) setting the central point of the instrument according to the size of a display window; (b) setting a graduation range, a graduation quantity and intervals between two adjacent graduations according to the maximum value and minimum value and a measured data size; (c) drawing the outer frame of a dial plate according to the central point and the size of the display window obtained in the steps (a) and (b); (d) drawing the inner frame of the dial plate according to the size of the outer frame obtained in the step (c); (e) drawing graduations of the dial plate according to the data values, the size of the outer frame and the size of the inner frame obtained in the steps (b), (c) and (d); (f) comparing an input measured data value with a corresponding value of a dial plate graduation, determining the position of a graduation where the measured data value is positioned, and drawing a watch hand, wherein the step is carried out repeatedly at a certain frequency. The method has the advantages of scientific design, more visual data display and higher easiness in reading.
Description
technical field [0001] The invention relates to a method for displaying measurement data, in particular to a method for displaying measurement data by using an analog indicating instrument. Background technique [0002] In most measurement software, the measured data is directly presented in numbers, especially for monitoring data such as power, speed, pressure, temperature, etc., it needs to be compared with other data to find out whether there is a difference in this measurement. In addition, in monitoring When the number is large, not only is it not easy to distinguish, but it is also easy to misread the number, causing misjudgment, making the monitoring work complicated and error-prone. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The object of the present invention is to provide a method for displaying measurement data by using an analog indicating instrument to solve ...
