Let’s say you work in super hero factory as floor manager. You are looking at the recent time sheet data submitted by your underlings and want to know who works more. So you did what any self respecting floor manager does. You made yourself a large cup of hot chocolate, whipped open Excel and created a column chart.
But now, you want to add a line to it at 6:00 PM (or some other arbitrary point) so you can clearly see which superheros are over working.
So how do you go about it?
Adding a line to column charts – Tutorial
This tutorial assumes you have a column chart. If you have a bar chart, you should use vertical error bars in step 6.
- In a cell, enter the value for your line. Say this is in C15 (and it has 6:00 PM)
- Add this extra point to your chart. At this stage you will get this.
- Take a sip of that scrumpdillycious hot chocolate.
- Convert the new series to as XY chart. Just right click on it and select “Change series chart type”.
- Add error bars to this new dot
- Excel adds both vertical & horizontal bars. We just need horizontal line. So remove vertical (Y) error bars.
Note: if you are adding the line to bar chart, remove X error bars instead.
- Set error bar value to 7 (same as number of categories – 1)
- Format the error bar
- Set error bar to plus side only
- Remove cap
- Set the line color and thickness
- Remove marker symbol (set it to no marker) so we have only line
- Chug the rest of your hot chocolate, we are done!
