Description
[technical field]
The present invention relates to a kind of statistics to show chart board, and specifically the present invention relates to a kind of adjustable exhibitions suitable for statistical work
Diagram plate.
[background technique]
Known, statistics is about a Men Xueke of understanding objective phenomenon total number feature and quantitative relation, it is by searching
Collection arranges, analysis statistics, recognizes the methodology science of objective phenomenon quantitative law；Due to statistical quantitative study
It is objective, accurate and verifiable to have the characteristics that, so statistical method just becomes the most important method of positive research, it is generally applicable
In natural, society, the analysis and research of economic, scientific and technical every field；It is the method needed using science as statistical work
It collects, arrange, a series of active procedures of analysis statistics, generally comprising statistics design, survey, sorting-out in statistics and system
Meter analysis four processes；Statistics can most be expressed is data, including statistical distribution, statistical packet, the series of distribution, statistical form, system
Count the manufacturing technology etc. of figure；In the production of statistical chart, common chart includes bar chart, line chart and sector diagram；Bar chart
" being also the phillips curve figure " is the figure for indicating data are how many with the height of bar shaped of same size or length.Bar chart
Can be horizontal or longitudinal, also referred to as column diagram " column chart " when longitudinal.In addition, bar chart has simple bar chart, compound
The forms such as bar chart, specifically bar chart is drawn out in plate face with bottom horizontal line and side vertical line, then in bottom
Horizontal line top is equidistant to draw a plurality of horizontal line, and in side, vertical line draws a plurality of equidistant vertical line towards another side direction, the bottom of at
Portion's horizontal line, which corresponds to, marks time, yield, population etc. at each vertical line；Then it is marked at each horizontal line of correspondence of side vertical line
Yield, investment, per capita output value etc. are finally drawn and the biggish same hue of plate face contrast in each vertical line by lower end to top
Or different color item, it gets information about and recognizes convenient for people and the acquisition of data；Similarly line chart is in addition to replacing with item
It is substantially identical as bar chart other than point and connecting line；Sector diagram " also known as fan-shaped chart of percentage comparison ", it is to indicate sum with entire circle,
Indicate that each section quantity accounts for the percentage of sum with the size of each sector in circle；It can will be apparent that earth's surface by fan-shaped statistical chart
Each section quantity is shown with the relationship between sum.
The chromatics paper that existing graphic making mostly uses greatly back to have adhesive sticker makes, when in use various data drawing lists
Can not adjust, thus after data update every time will secondary production chart, waste is very big.
