Ever wanted to make an area chart with up down colors, something like this? Then this tip is for you.
How to create area chart with up / down colors?
Simple. You need,
- Data with positive & negative values.
- optional: A cup of coffee or a cold beverage of your choice.
Start by creating a regular area chart. You will get this:
Now, select the are and go to format settings (use shortcut CTRL+1).
Go to fill color for the area and change it to gradient fill.
Set it to one of the default gradient fills, you will see a screen like this.
The last step: Setting two color gradient
We are nearly there. Take a victory sip out of that coffee cup or cold beverage. First calculate the mid point for our gradient stops. This will be =maximum up value / (maximum up value + maximum absolute down value)
For example, if your data has +5 has maximum positive value and -5 as maximum negative value, then the gradient stop will be 50% since 5 divided by (5+5) is 50%.
Take another sip and set the gradient stops as shown below.
- Create 4 gradient stops (most of the default gradient settings have 4 stops)
- Set stop 1 & 2 to positive color (say blue)
- Stop 3 & 4 to negative color (say red)
- Adjust the position of 2 & 3 to the gradient stop calculation you have done earlier.
- Make sure Gradient is linear with 90 degrees
Done. Your area chart with positive / negative colors is ready. Admire its beauty while finishing your beverage.

Thanks, Chandoo, for tutorials. Learned a lot.
Unfortunately could not learn about the running biker.
The link "Target vs. Actual with Biker on a hill chart" has a link to another tutorial.
I would like to see the biker! 🙂
Thanks for letting me know. I fixed the URL error. Here it is - Visualizing target vs. actual progress – Biker on a hill chart
Thanks, Chandoo.
Now I am enlighted!
This only works if the highest value and lowest value are the same. Which makes it kind of pointless. If the goal is to have one colour below 0 and another above, when negative might only go down to -10 and positive up to 50, this will never work. Actually found it to be a waste of time.
