excel怎么画双对数图(excel绘制双对数曲线)

1. excel绘制双对数曲线

一、获取正态分布概念密度

正态分布概率密度正态分布函数“NORMDIST”获取。

在这里是以分组边界值为“X”来计算：

Mean=AVERAGE(A:A)(数据算术平均）

Standard_dev=STDEV(A:A)(数据的标准方差）

Cumulative=0(概率密度函数）

二、向下填充。

三、在直方图中增加正态分布曲线图。

1、在直方图内右键→选择数据→添加→。

2、系列名称：选中H1单元格。

3、系列值：选中H2:H21。

4、确定。

四、修整图形

1、在图表区柱形较下方选中正态分布曲线数据，（正态分布密度值和频率数值相比太小了，实在看不清，多试几次，选中后如图，同时正态分布曲线那数数据处于选中状态）。

2、右键→设置数据列格式→系列绘制在→次坐标轴；

关闭，如图。

五、更改系列图表类型

1、选中正态分布柱形图→右键→更改系列图表类型。

2、选中“拆线图”。

3、确定。

六、平滑正态分布图。

选中正态分布曲线→右键→设置数据列格式→线型→勾选“平滑线”→关闭。

大功告成！！！

2. excel怎样画双对数图

1、电脑打开Excel表格，然后输入对数公式=log，然后选择第一个LOG。

2、点击选择LOG后，就可以看到要输入数值和底数。

3、先输入数值，以64为例，然后输入逗号，在输入底数2。 3、输入公式后，按回车键。

4、就可以得到64以2为底的对数了。

3. 如何用excel绘制双对数曲线

1、打开电脑，然后点击打开excel中准备好的工作表，然后点击插入选项，然后点击图表选项，然后点击散点图选项；

2、然后新建一个图表，然后在图标页面的上方菜单栏中添加系列－选择X轴数据和Y轴数据；

3、双击X轴，弹出X轴坐标轴格式，修改X轴数据，对数图表是以10为底，所以刻度单位选10，把下面对数刻度打上勾，Y轴与X轴相同；

4、修改完后点击图表选项，将网格线中的X轴和Y轴全部勾上，点击确定按钮，这样就完成对数图表的绘制。

4. excel绘制双对数曲线的方法

1、首先双击桌面上的excel图标打开excel。

2、在excel中输入做曲线拟合的数据。

3、选中所有输入的数据。

4、点击上边栏中的插入。

5、选择插入弹出框中的图表选项。

6、当弹出图表向导弹出框时，点击左边的XY散点图。

7、选择子图表类型中的第一个。

8、点击图表向导对话框最下方的完成。

9、此时会根据数据生成一个图表。

10、选择图表中的任意一个点，图表中的所有点都会被选中。

11、右键点击任意一个点，选择添加趋势线。

12、此时会弹出添加趋势线对话框，选择类型中的第一个。

13、点击选项，勾选下方的显示公式和显示R平方值选项。

14、点击对话框下方的确定。

15、此时数据的曲线拟合的公式可以了。
