Description

Novel statistics drafting scale

Technical Field

The utility model relates to a surveying and mapping instrument's technical field specifically is a novel statistics mapping ruler.

Background

The statistical chart is a relatively intuitive data expression method, the statistical chart generally comprises a curve graph, a trend graph, a bar graph and the like, each data point is marked in a coordinate system in the statistical charting process, then the chart is subjected to thinning processing based on each data point, and it can be seen that accurately marking the data point is an extremely important link in the statistical charting. The existing drafting scales are generally long-strip scales, and in order to determine a data point, a corresponding point needs to be found on an X axis by using the long-strip scales, then a line parallel to a Y axis is drawn along the point, then a corresponding point is found on the Y axis, a line parallel to the X axis is drawn, and the intersection point of the two lines is the data point to be found, which is time-consuming, labor-consuming and inefficient, for example, the patent with the application number of 201420667690.1 Y coordinate locating plate constitutes sliding fit simultaneously, dotting slider bottom is equipped with the device of dotting that is used for dotting on the paper, though easy operation need not any supplementary line segment and just can pinpoint the coordinate point, but the drawing of circle of being not convenient for, it is fan-shaped to draw, leads to efficiency slow excessively.
