- Highlight your data range and click Insert > Chart.
- Select “Scatter with only markers” as chart type.
Before moving on, double check your data for accuracy. Get the most out of your logarithmic scale chart by following our tips for preparing your data. You won’t regret it! Start now.
Tips for Preparing Data
Ready to create a logarithmic scale chart in Excel? Here’s how to do it:
- Prepare your data. Get your x-axis values (independent variables) and y-axis values (dependent variables) in two separate columns.
- Calculate logarithms. Use the “LN” formula in Excel to get the natural logarithms for each y-axis value. Put them in a column next to the y-values column.
- Plot on a logarithmic scale. Use logarithmic scales for both axes on your graph.
Remember, your data needs to be accurate and organized. Poor data prep could skew your results and cause you headaches down the line. So get it right the first time!

Choosing the Right Chart Type
Choosing the right chart type is essential. Consider what you wish to achieve with your data presentation, who will view it, and any time constraints. The goal is to create a clear representation that effectively communicates its message.
Using the wrong chart type can have serious consequences. For example, news channels in the recent US Presidential Election were inaccurately reporting poll percentages due to the unsuitable chart type they used.
Now that you know how to choose the right chart type, let’s talk about creating a logarithmic scale.
Creating a Logarithmic Scale
Making a logarithmic scale is essential to creating a log-log chart in Excel. Follow these steps to make it easy:
- Right-click on the column of data for the Y-axis. Then, select ‘Format Cells’ and the ‘Number’ tab. Go to Categories and pick ‘Logarithmic’.
- Set the logarithm base value in the ‘Base’ box. Experiment with different values to see what works best.
- Format the X-axis in a similar fashion. Right-click, ‘Format Cells’, ‘Number’ tab, select ‘Logarithmic’ from Categories.
- To finish, create a scatter chart with logarithmic values. Pick ‘Chart Type’ and then ‘Scatter with Smooth Lines’ chart. Your log-log chart will now show both axes using logarithmic scale.
Logarithmic scales are great when plotting data that varies over many magnitudes. Give equal visual weight to each order of magnitude, not just the larger values.
Fun Fact: In 1614, John Napier, a Scottish mathematician & theologian, discovered logarithms & published them in his book ‘Mirifici Logarithmorum Canonis Descriptio’.

Selecting Chart Styles
To select chart styles, here are the steps to follow:
- Click your chart to activate it.
- Go to the ‘Chart Design’ tab at the top of Excel’s ribbon.
- Click the ‘Change Chart Type’ button in the ‘Type’ group.
- Choose a type of chart that fits your data and select ‘OK’.
Chart style matters since it affects how people interpret graphs. It should be neat, tidy, and easy to read.
The chart style you choose depends on what you wish to emphasize in the data. If displaying multiple sets of data over time, a line graph may be better than a bar graph for showing trends.
Also, pick colors that contrast well and aren’t too bright. Too many bright colors can make it difficult for people to focus on the important elements.
Don’t forget to label axes, add units of measurement, and legends. This helps people understand the content more easily.
Lastly, we’ll cover how to add Chart Titles naturally with ease.
Adding Chart Titles
- Select the chart area by clicking on it.
- Locate the “Chart Elements” button at the top right of your Excel chart.
- Tick the box next to “Chart Title“.
- A title box will appear above or beside your chart, based on how you want it placed. Type in the title of your choice.
Make your chart titles clear and simple. For instance, if you plot website traffic over time, use a title like “Monthly Website Traffic from January-December“.
I recall working on a project that needed me to make a few Excel sheets with graphs and charts. My team praised my data visualization skills, as they could easily understand what my graphs were showing. However, when I reviewed my work later on, I realized that I had forgotten to add titles! Without explanations, even I found it hard to identify which graph was what.
After Adding Chart Titles, you should Label Axis.
- Select the chart. Go to the Chart Design tab. Click Add Chart Element. Select Axis.
- Click the text box next to Horizontal or Vertical Axis.
- Highlight the text box. Use the Format tab to change fonts, colors, etc.
Provide context for your chart. Label horizontal and vertical axes accurately. Do this so others can easily understand.
Pro Tip: Click one of the axis labels twice. Select ‘More Options.’ Choose where the label appears. Make other adjustments as needed.
Show data trends visually. Add a Trendline.
Adding a Trendline
Excellent! Let’s discuss adding trendlines to your Excel chart. It’s a valuable feature in data analysis. It shows trends and patterns that could be difficult to spot. We’ll look at two parts of the process: selecting options and customizing them to your demands. After this, you’ll be an expert in making your chart work for you and showcasing the data you need.

Selecting Trendline Options
To select trendline options in Excel, click on the chart and locate the green plus sign on the right. This will open a menu with various options. Select “Trendline.”
Follow these 6 steps:
- Choose the type of trendline (linear, exponential, logarithmic, etc.).
- Pick if you want to show the equation and/or R-squared value.
- Decide where to display the equation/R-squared value (above, below, left or right of chart).
- Choose if you want to forecast future data points.
- Specify the units for the forecasted data points.
- Select any additional formatting options.
Your trendline will appear! It shows trends over time and can predict future patterns. Select the right type of trendline, so that it accurately predicts. The R-squared value helps determine how well the model fits.
Don’t miss out on this tool. Customize the trendline to best fit what you’re presenting in your graph!
Customizing the Trendline
To customize your trendline, start by clicking on it. Then click on “Format Trendline” in Excel. Choose a color or line style that stands out from the data series. You can add a label for your trendline by ticking the “Display Equation on Chart” or “Display R-squared value on chart” boxes.
This customization not only makes the chart look neat, but also helps your audience better understand what you’re presenting. Colors that contrast with the data series make it easier to identify each series. Labels with equations and R-squared values help explain any relationships or patterns between variables.
For more aesthetic appeal, experiment with different colors and styles that complement the data’s theme. Contrasting line styles or alternating colors can create a clear separation between datasets. Consider adding labels that indicate subcategories and axes with correct values.
Now let’s finish off our logarithmic scale chart!
Finalizing Your Logarithmic Scale Chart
Approaching the end of making a logarithmic chart? Here are some key elements to remember:
- Data tables – these give the viewer context and help them understand.

Adding a Data Table for Context
To add a data table to your logarithmic scale chart, here’s what to do:
- Click on the chart to access Chart Tools.
- Go to Layout then click Data table.
- Select where you want it (above or below).
- Choose horizontal or vertical orientation.
- Change font size and color, if needed.
- Make sure the data table can be read in relation to chart.
Adding a data context can clarify things and support any points made in the chart. It can help viewers quickly comprehend what they’re seeing and reinforce key takeaways from your message.
For instance, if you’re using a logarithmic scale chart to compare website traffic patterns over time, including a data table to explain what each line represents will make it easier for the audience to identify which site they’re looking at and how each is performing.
I remember working on a project where we created a logarithmic scale chart comparing sales figures across different regions. We presented our findings at an important board meeting. Ultimately, half of them didn’t understand what they were looking at since there was no context. Adding a data table in later presentations made our findings more accessible and understandable.
Next up: Including a Legend…
Including a Legend
Open the spreadsheet with the logarithmic chart.
Click on the chart you want to add a legend to.
Go to the Chart Design tab, then click Add Chart Element. Choose Legend.
A box will appear with location options: top, bottom, left or right.
Choose the location and format of your legend. Customize its properties in Excel.
The legend lets readers match colors and symbols from the graph to the variables or categories. It’s helpful for complex graphs and charts, as it leads readers’ eyes through each part of the graph.
Adding a legend makes it easier to tell the difference between the multiple lines plotted in the chart, if there are bars or lines used as points.
Pro Tip: Don’t include too many variables in each axis of the chart, as it may confuse readers even with a legend. Keep it simple, but don’t miss the insights into the trends and patterns in the data visualization!
Polishing Your Chart for Presentation
Polishing Your Chart for Presentation requires refining the details. Here are some tips to help you get started:
- Pick a clear font that suits your design. Avoid fancy or overly stylized fonts, as these can be difficult to read, especially in small sizes.
- Use consistent colors throughout your chart. Highlight important data points with bold or contrasting colors. Make sure the colors are easy on the eyes and viewers can differentiate between data series.
- Add labels to each axis. This will help viewers understand the data and how to interpret it.
- Add annotations or callouts to draw attention to specific data points or trends. This could include arrows, circles, or text boxes.
- Review your chart from a viewer’s perspective. Ask yourself if it effectively conveys the information. Make any adjustments until you’re satisfied.
Additionally, limit unnecessary distractions like gridlines, optimize margins, add a title, use appropriate units, and explain unfamiliar data. This should help create an effective chart presentation that communicates insights without losing its message.
