Excel 2007: How To Add a Trendline to a Chart

Posted February 12, 2007 by Rob Rogers in Microsoft Excel

Trendlines are useful for revealing patterns or trends in your data. They are mostly used in XY scatter charts but are also useful in line, area, and bar charts. To add a trendline to your chart, follow these instructions…

1. Select the chart.

2. Select the series you wish to use to create the trendline.

3. Go to Chart Tools, select the Layout tab and click Trendlines.

4. Select the type of relationship you are expecting the data to reveal, your choices are Linear, Exponential, Linear Forecast, or Two Period Moving Average. You can also select More Trendline Options to reveal even more types.

5. Right-click the newly created trendline and select Format Trendline. Use the Line Color, Line Style and Shadow sections to modify the look of the trendline.

6. Click Close.

    Not e: this only works with 2D charts. Excel won’t let you add a trendline to a 3D chart type

    Why is the help so much worse than previous versions.

    Its pretty sad really. I’ve noticed this with MS products over the last few releases. Google out performs help on all levels from low end user apps to server products.

    A excel help search, brings up the mathmatical theory behind trend lines!

    thanks for posting this though cheers

    I don’t have trend line button on the ribbon tab.How to get the trend line in there?

    • TBright163

      I think you have to select the axis you want to use to add the trend line to, then you can select the Layout menu and find the trend button.

  • Joe Camilleri

    I have 2 major problems with SOME date/value charts in Excel 2007
    (a) the moving average plots before the last data point, e.g. in range of 10 dates/values, the trendline for a 3 deep MAV is plotted along points 2 to 8 only.
    (b) if the data series is vertical and in descending date order, so I can only get a left-to-right history in the plot if I ‘reverse’, which then shifts the value scale (y-axis) to the right of the chart. How can I have both the axis on the left hand side and the left-to-right history?

    Grateful for any help from anyone.
