1] Creating a chart
Enter the data for which you want to create a chart.
Next, select the data and choose ‘Insert’ tab.
Scroll through the category of ‘Recommended Charts’ and click any chart to get a preview of the data (If you don’t see a chart you like, click All Charts to see all the available chart types).
2] Adding a trendline
After having created a chart, select it, and hit the ‘+’ icon visible adjacent to the chart.
Scroll down the list of options and select ‘Trendline’.
Click the side arrow to view more options and choose the desired option.
Please note that Excel displays the Trendline option only when you select a chart that has more than one data series, without selecting a data series.
3] Formatting a trendline
Again, press the ‘+’ sign, choose ‘Trendline’, scroll down and select ‘More options’
When the Format pane becomes visible, select the trendline option in the dropdown list.
By default, Excel inserts a linear trendline. However, you can add other variations of your choice like,
- Exponential
- Linear
- Logarithmic
- Polynomial
- Power
- Moving Average
Set a value in the Forward and Backward fields to project your data into the future. Formatting a trendline is a statistical way to measure data.
4] Add a moving average line
If you feel like formatting your trendline to a moving average line, you can do so. For this,
Click anywhere in the chart.
Switch to the ‘Format’ tab, and under its ‘Current Selection’ group, select the trendline option in the drop-down list.
Next, click ‘Format Selection’ option.
Then, from the Format ‘Trendline‘ pane, under ‘Trendline Options‘, select Moving Average. Specify the points if necessary. (Kindly note that the number of points in a moving average trendline equals the total number of points in the series less the number that you specify for the period).
