The preview shows how to create a scatter chart within seconds and how to turn it into a bubble chart by adding Z-values.

预览显示了如何在几秒钟内创建散点图中，如何变成一个气泡图加入的Z -值了。

Popular multivariate visualization such as scatter plot matrix,parallel coordinates,star plot,Andrews plot have long history and widely application,but a united theoretical basis is absent up to now.

常用的多元数据可视化方法如散点图矩阵、平行坐标、雷达图、三角多项式图等具有悠久的历史和广泛的应用，但是长期以来缺乏统一的理论基础。

The samples for linear regression, the broken line analysis and plot analysis, the thesis found that the listed company news that foreign direct investment is the lack of access to a very earnings in the stock market reaction to the impact of factors, single company the non-recurrent yield and investment opportunities between the companies is a positive correlation between the operators while the Cause exists a negative correlation between.

通过对样本进行线性回归、折线图分析和散点图分析，本文发现上市公司的对外直接投资消息宣布无法获得一个正的非常性收益，在对股票市场反应产生影响的因素中，单家公司的非经常性收益率与公司投资机会间存在正相关关系，与经营者动因间则存在负相关关系。

Methods At first, the relationship of linear or non-linear between dependent X and independent Y in original data can be distinguished by scatter diagram which can be made through Excel software.

方法通过利用Excel可绘制散点图的功能，了解原始数据自变量X和因变量Y间的线性与非线性关系，并由自变量X和因变量Y的自然对数转换后的散点图的情况，决定采用何种曲线拟合。

Methods At first, the relationship of linear or non-linear between dependent X and independent Y in original data can be distinguished by scatter diagram which can be made through Excel software. The scatter diagram of log- arithmic transformation between dependent X and / or independent Y decides which curve to be fitted.

通过利用Excel可绘制散点图的功能，了解原始数据自变量X和因变量Y间的线性与非线性关系，并由自变量X和因变量Y的自然对数转换后的散点图的情况，决定采用何种曲线拟合。

In a scatter diagram, when the dots are distributed roughly along an ascending tendency, there is a positive correlation between the two sets of data. On the contrary, when the dots are distributed rough along a descending tendency, there is a negative correlation. However, when the dots scatter irregularly without a pattern, there is no obvious correlation.

在散点图中，如果点的分布大致上是由左下方至右上方，图像表示两组数据间有一个正相关关系；如果点的分布大致上是由左上方至右下方，图像表示两组数据间有一个负相关关系；如果点的分布大致上是不规则/凌乱地分布，图像表示两组数据间没有一个明显的关系。

Some kinds of data analysis and statistics methods, including principle factor analysis, factor loading analysis and dicrimination function, ternary diagram, scatter diagram are used to determine the material source of one piston core DGKS 9617 recovered from the northern part of the East China Sea and one bore core EA01 from the northeast part of the East China Sea.

中文摘要：采用数理统计（包括主成分分析、因子得分分析和判别函数），微量元素比值三角图和二维散点图，运用综合分析判别的方法判断东海北部柱样DGKS9617和东海东北部钻孔EA01物质来源。

Commonly required capabilities for analysis of variance, analysis of covariance, and regression analysis are closely linked with graphical tools that produce scatter plots, histograms, box-and-whisker plots, and contour plots.

通常所需的方差分析，协方差分析和回归分析的能力是和能够产生散点图，直方图，箱线图，等高线图的图形化工具密切联系在一起的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
