Graphs and charts are an important visual aid that helps individuals in different fields to understand numerical data and make better decisions. Among the different types of graphs, logarithmic graphs have proven to be effective in presenting large data sets. In this article, we will discuss how to create logarithmic graphs using Microsoft Excel.
Making Graphs in Logarithmic View with Microsoft Excel
Microsoft Excel has powerful features that allow users to create different types of graphs, including logarithmic graphs. Here are the steps to create logarithmic graphs:
- Open Excel and enter your data in a worksheet.
- Select the data you want to graph.
- Click on the “Insert” tab and choose a chart type. Column and line charts are common choices for logarithmic graphs.
- Once you have chosen the chart type, select the chart style you want to use. You can customize the colors, layout, and other elements of the chart later.
- Click on the chart to activate it. Then, click on the “Chart Design” tab to access additional options. For logarithmic graphs, you may need to adjust the scale of the vertical axis to logarithmic. To do this, click on “Add Chart Element” and select “Axis Titles.” Then, choose “Primary Vertical Axis Title” and select “Title Below Axis.” Finally, select “Logarithmic Scale” and Excel will automatically update the axis scale.
- Customize your chart by adding titles, labels, and other elements as desired.
- When you are ready to save or share your chart, click on the chart and choose “Save As” or “Copy” to use it in a presentation, report, or other document.

Another useful application of Excel is creating charts that represent salary scales. By using the trend method, we can make a chart that shows the salary increases based on the years of experience. In this example, we will use Gadjian’s illustration of salary structures for easy visualization of the example.
Here’s how to create a salary scale chart in Excel:
- Open Excel and enter your data. You will need to include the salary figures for different levels of experience, as well as the number of years for each level.
- Select the data you want to graph.
- Click on the “Insert” tab and choose the chart type that suits your data. In this example, we will use a line chart.
- Customize your chart by adding titles, labels, gridlines, and other elements as desired.
- When you are ready to save or share your chart, click on the chart and choose “Save As” or “Copy.”
Cara Membuat Kurva S di Microsoft Excel
Curva S or S-curves are commonly used in business to show the cumulative change in quantity over time. S-curves can also represent the adoption of new technologies, market trends, and other phenomena. In Excel, creating S-curves is relatively easy and can be done in a few steps:
- Open Excel and create a table with the following headers: “Time,” “Cumulative Quantity,” and “Rate of Change.”
- Enter the data under each column. For example, under “Time,” you can list the months in chronological order.
- Select the data you want to graph.
- Click on the “Insert” tab and choose the scatter chart type.
- Right-click on the chart and choose “Select Data.”
- Click on “Add” to add a new series.
- In the “Edit Series” window, type a name for the series and select the values for the X and Y axes. The X values should be the time column, and the Y values should be the cumulative quantity column.
- Click “OK” to close the window.
- Repeat the process for the other series by choosing “Add” and selecting the values for the X and Y axes. This time, you should select the rate of change column as the Y values.
- Customize your chart by adding titles, labels, and other elements as desired.
- When you are ready to save or share your chart, click on the chart and choose “Save As” or “Copy.”
Cara Menghitung Logaritma dengan Fungsi LOG Excel
Excel offers several functions for calculating logarithms, including the LOG function. You can use this function to calculate logarithms of different bases, such as base 10, base 2, or natural logarithms. Here’s how to use the LOG function:
- Open Excel and enter the value you want to calculate the logarithm of in a cell.
- In another cell, type “=LOG(value,base)” where “value” is the cell that contains the value you want to calculate the logarithm of, and “base” is the base of the logarithm you want to calculate.
- Press “Enter” to calculate the logarithm.
For example, if you want to calculate the base 10 logarithm of 100, you would type “=LOG(100,10)” in a cell and press “Enter.” Excel would return the result of 2 because 10 raised to the power of 2 equals 100.
FAQ
What are logarithmic graphs used for?
Logarithmic graphs are used to represent large data sets that vary widely in magnitude. They compress the data by using a logarithmic scale that reduces the distance between values at the lower end of the scale, making it easier to see the details of small changes in the data. This type of graph is useful for presenting information about scientific and financial data, such as population growth, stock prices, and earthquake Magnitude scale
What is the difference between linear and logarithmic scales?
Linear scales are used for data that has a consistent increase or decrease, while logarithmic scales are used for data that varies widely in magnitude. Linear scales have equally-spaced intervals, while logarithmic scales have increasingly-spaced intervals. Logarithmic scales compress the data at the lower end of the scale, which makes it easier to view small changes in data. In linear scales, every increment represents the same unit increase.
