Introduction: Recently doing a project plan, which involves data analysis, the data analysis presentation if there are more choices then, hope that through reading this book has a good harvest, expecting yo
Chapter One: Select the chart
A common Five chart: pie charts, bar charts, bar charts, line charts, scatter
Second, the three-step drawing: ② ① clear information to be expressed relative relationship information relationship determining a chart selection ③
1, the information to be clearly expressed (from data to information)
A different set of data dimensions to see, will interpret a different conclusion, they want to give readers a clear interpretation of how important small coup: the information can be expressed as the chart title, for example: "salary and years of service does not matter," " company sales in 2019 increased 2-fold. "
2, clear information on the relative relationship (relative relationship to information from) (common five kinds of relations)
① component relative relationship: percentage of the overall (pie chart majority)
② the relative relationship between the project: project ranking (keyword: greater than, less than, quite)
③ time series ~ ~: How to change over time (Keywords: change, growth, increase, decrease, decrease, down and up and down fluctuations)
~ ④ frequency distribution: the distribution of the project (including the number of items within each value, "Most shipments concentrated in the 5-6 days delivery", keyword: Y from X to concentrate, frequency and distribution)
⑤ related ~~: relationships between variables (keyword: ... and is related with the increase ....)
3, select a chart (from a relative relationship to the chart)
1, the component relative relationship
① is best to use a pie chart
② should not be more than six kinds of ingredients
③ eye habits clockwise, an important component into the 12 o'clock position, highlight color - black and yellow contrast, increased shadow
2, the relative relationship between the project
① multi-purpose bar
② ordinate the project name, they can be arranged in a certain order, such as: company size, create order, etc.
③ contrasting colors important item; and the scale values do not use the same time, good numerical decimal point is omitted (but please the case may be); bar width is greater than the gap width
④ common bar chart:
⑤ bar and histogram distinction:
1) reduce the time series of the relative relationship misunderstanding
2) there is enough space to lay down a lengthy legend, not to this line
3, time series opposing relationship
① multi-use bar charts and line charts
1) fewer points histogram (7-8), whereas FIG polyline
2) the time of occurrence histogram emphasize the number of levels, small pieces of time; line chart emphasizes trends
② common column chart
③ packet line chart
4、频率分布相对关系（预测风险、可能性或机会）
①多用阶梯式柱状图和折线图
②范围大小：最好5≤X（点或柱）≤20；分组大小：规模大小基本一致（0-9、10-19、20-29等）
③图形示例
5、相对性相对关系
①多使用散点图或条形图
②用于论证两个变量符合或不符合我们的预期
③区分使用条形图和散点图：组（小于15）较少可用条形图：使其中一个变量按照一定的顺序排列，查看另一个变量是否镜像显示
④散点图变体：
