Abstract

The invention relates to the technical field of economics teaching, in particular to a bar chart plotter for economics teaching. The bar chart plotter comprises an L-shaped assisting plate, a drawing ruler and a sucker; the L-shaped assisting plate is formed by a horizontal plate and a longitudinal plate vertical to each other; the drawing ruler comprises two longitudinal rulers arranged in parallel and a horizontal ruler; the horizontal ruler is vertically arranged between the two longitudinal rulers of which the upper surfaces are provided with scales; a plurality of through slot groups are arranged at the side surface, close to the drawing ruler, of the horizontal plate in a penetrating mode, and each through slot group comprises two through slots corresponding to the longitudinal rulers; the longitudinal rulers are telescopically arranged in the through slots; the sucker is arranged at the back surface of the horizontal ruler; the height of the sucker is equal to the interval between the back surface of the horizontal ruler and the back surface of the horizontal plate. The bar chart plotter for economics teaching is used for quickly drawing a bar chart and is high in precision.

Description

technical field [0001] The invention relates to the technical field of economics teaching, in particular to a bar graph plotter for economics teaching. Background technique [0002] When teaching economics, teachers need to use a ruler to draw a bar graph with chalk on the blackboard to explain the correspondence between various parameters, but drawing a bar graph with a ruler is inefficient and is not conducive to improving the quality of teaching. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bar graph plotter for economics teaching that can quickly draw bar graphs and has high precision. [0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: a bar graph plotter for economics teaching, comprising an L-shaped auxiliary plate formed perpendicular to each other by a horizontal plate and a vertical plate; comprising two vertical ruler...
