Let's be real - staring at raw numbers won't tell you where your business is headed. That's where trendlines come in clutch. They're like having a data crystal ball, showing you the hidden patterns in your numbers. And guess what? With AI tools like Excelmatic, this whole process just got way easier.
Why Trendlines Are Your New Best Friend
Whether you're tracking sales, website traffic, or customer growth, a line of best fit helps you:
- Spot trends before they're obvious
- Make smarter predictions
- Present your data like a pro
The best part? You don't need to be a math whiz anymore. Modern AI tools can handle the complex calculations while you focus on the insights.
Getting Your Data Ready
First things first - let's get your data into Google Sheets:
- Open Google Sheets (it's free with your Google account)
- Either type in your numbers or import from CSV/Excel
- Pro tip: Clean up your data first - remove duplicates, fix formatting
Creating Your Scatter Plot
Here's where the magic starts:
- Highlight your data range
- Click Insert > Chart
- Change the chart type to "Scatter chart" (this is key!)
Scatter plots show each data point individually, making trends easier to spot than with bar or line charts.
Adding That Sweet Trendline
Now for the main event:
- Click on your chart to open the editor
- Go to Customize > Series
- Check the "Trendline" box
Boom! Your line of best fit appears instantly. But we're just getting started...

Reading Between the Lines
Your trendline tells a story:
- ↗️ Upward slope = Positive trend
- ↘️ Downward slope = Negative trend
- ➡️ Flat line = No clear trend
Check the R-squared value too (find it in trendline options). Closer to 1 means your line fits the data well.
