1. excel对数图 坐标
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。
2. excel对数坐标系
对数坐标指的是在二维直角坐标系下对数图像对应的各点所处的位置,x称为点A的横坐标,y称为点A的纵坐标。
若一个数x(x>0)经过一个对数函数作用后变为y,如:y=ln(x),那么由x和y组成的二维向量(x,y)在二维坐标系下对应的点的集合,就称为一个点A(x,y)的对数坐标。
3. excel对数坐标轴
先简单了解一下对数坐标和半对数坐标的特点。半对数坐标图表如下图,是其中一个坐标轴以对数的形式存在(如x轴),另一个还是普通的算数坐标轴(如y轴)。双对数坐标轴则是两个坐标轴都是对数的形式。
首先录入实验数据。前一列为横坐标,后一列为纵坐标。
可以看出,横坐标的数值差距太大,普通坐标系难以表示,因此选择半对数坐标系。选择“插入”——“图表”——“XY散点图”
随便点击横坐标中的一个数,从右侧出来坐标轴选项。
在“坐标轴选项”中的“对数刻度”处单击,就成功的将横坐标轴变为对数坐标轴,
其中,默认基准为10,即横坐标是1,10,100,1000……
同时可以更改最大值和最小值,使得图表更加清楚美观。如图。
除此之外,最好使网格线也展现出来。在图表元素中选择“网格线”,勾选“主轴次要垂直网格线”
可以使网格线更加清楚,点击任意一条垂直网格线,出现如图效果。
在“属性”下的线条中,选择“实线”。一个半对数坐标图表就做好啦。
4. excel横坐标对数
如果在Excel图表中系列之间值的跨度比较大,图表中较小的数值不能明确显示,就可以使用“对数刻度”。;设置“对数刻度”的方法:;
1、首先在excel表格中插入一个直方图的图表,可以看到此时坐标轴显示的数据较多,数值较大。;
2、右键点击纵坐标轴的位置,在打开的选项中点击“设置坐标轴格式”选项。;
3、然后在打开的左侧的设置窗口中勾选“对数刻度”,并设置需要的“底数”。;
4、即可将表格的纵坐标设置为对数刻度的样式,且底数为“10”。
5. 对数坐标 excel
Excel表中计算对数步骤如下:
1、首先自己制作一个辅助计算的表格,将对数的底数和实数分别放到两列当中,然后将对数计算结果放到第三列。
2、选中对数结果的一个单元格,然后点击Excel的函数图标fx。
3、在弹出的插入函数对话框中,可以对函数进行选择先选择函数的类别,在函数类别下拉菜单中我们选择数学与三角函数。
4、然后在选择函数里的LOG,这是对数计算的函数。
5、在弹出的函数参数对话框中,需要对Number(实数)和Base(底数)进行指定。
6、根据自己编制的辅助计算的表格,将对应的实数和底数链接过来即可。
7、链接好数据之后点击确认,对数的结果已经自动计算出来了。
6. excel双对数坐标图
1、点插入>图表,会看到一个柱状图。
2、双击柱状图,会出现excel表格,在里面柱状图点右键》数据源。看到数据在sheet1里,可以修改成自己的数据。
3、右键点柱状图,修改“图表类型”。分别把几个柱状图改成XY散点图。
4、在数据B 列插入一列,从0开始,0、1、2、3、4、5、6、7,点数据源修改X Y 值,让折线从0开始终。
5、设置图表,把里面的主网格线,去掉。
6、关闭excel后,word里出现想要的图表。
7. 对数坐标周线图 Excel
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!!!

8. excel2010双对数坐标图
Excel双对数坐标系中看斜率,点击“插入”,找到“折线图”,选择第一项折线图;
点击“选择数据”,点击添加;
填入系列名称X轴,系列值Y轴,点击确定即可出现曲线图;
右击曲线图,点击添加趋势线,在弹出的对话框中选择线性和显示公式,点击确定;
确定之后可以看到出现一条拟合曲线以及公式,则曲线斜率为公式里X前面的系数。
9. excel半对数坐标图
选中坐标,然后双击出现格式设置,在刻度里将自动下面的对号全部勾去,然后设置自己需要的最大值,最小值,最大单位,最小单位。
双对数坐标指的是两个坐标轴的单位长度都是经过对数计算后的平面坐标系。对数坐标系统的坐标轴是按照相等的指数增加变化表示的。双对数坐标指两个坐标轴是对数坐标,即假如对应于x、y轴,则两轴等刻度情况下,其值以相应底数成次方增长。10. excel画对数坐标图
先在excel里面输入数据,然后插入表格。
选中横坐标的一个数字,点右键,有坐标轴格式。
然后选择对数坐标。
然后再选中纵坐标的一个数字,点右键,有坐标轴格式。
然后选择对数坐标。
最后,根据数字大小调节一下横纵坐标的最大值最小值就可以了。
