Let’s learn how to create a color changing line chart using Excel. This is what we will create.
Looks interesting? Read on.
Why color changing line charts?
I will be honest. These charts offer no new information. The height of line already encodes the information we need. Color is merely an eye candy. But sometimes you may want some eye candy. If so, you can use this tutorial.
Let’s look at the data:
Let’s say we have some data for 3 months starting 1-SEP-2015 in a table like below. We need to add 3 extra columns – Before, Line & After as shown in the below picture.
What are these 3 columns?
- Before: This is value – 1
- Line: this is simply 1
- After: We first calculate the maximum possible value (let’s say 160) and then subtract value from it. ie 160-value.
Create a stacked area chart from Before, Line & After data:
Select all three columns (before, line & after) and create a stacked area chart.
This is what we get:
Fill plot area with red yellow green gradient
- Select plot area of the chart and fill it with a Red-Yellow-Green gradient (see below)
Fill colors in before, line & after series
- Select before series and fill white color
- Select after series and fill white color
- Select line series and fill it with no color (ie make it transparent)
This is what we get:
Adjust vertical axis maximum
to 160 (or any other value as used in your calculations earlier)
At this stage, our chart looks like this:
Clean up and format the chart:
- Adjust horizontal axis labels
- Set up a chart title
- Remove legend
Now, our color changing line chart is ready:

Would you use such a chart?
I find very few uses for this chart. Also, when creating this chart using area chart technique, we loose the ability to add grid lines (as they are covered by the white color filled areas).
What about you? Would you use color changing line charts? Please share your thoughts and suggestions in the comments section.

Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!
Whyyyyyyyy?
The idea is to tell how to make a bubble chart. I got an e-mail from a reader recently asking how the scatter bubble is made. So I thought a 15 second tutorial would be a good idea to show this.
Did that email go "Dear Chandoo, I know that you scorn bubble charts, but if I don't do one in Excel for my boss then he'll fire my sorry ass, and my children will have to be sold for medical experiments in order for me to be able to afford the upgrade path to Excel 2010"?
If so, fair enough...it's all in the greater good 😉
Chandoo,
I am using excel 2003 and it is not working. The x axis is not the one that I enter in x axis column. Please help! Thanks.
Sorry, after few attempts, I managed to get the right result. I shouldn't select the title (header) of the table and select only the data to produce the right bubble chart.
What's wrong with bubble charts? Is there a better method for displaying scatter plots with lots of overlapping data points? Don't tell me you'd rather jitter!
@Sanwijay: Cool.
@Precious Roy: There is nothing wrong with bubble charts. Infact, it is the only way to show 3 dimensional data (x,y and sizes) without confusing your audience. Jeff is worried that people might misuse the chart. As with any chart, bubbles also have a place and time for using them.
I recommend using bubble charts to show relative performance various products in several regions and similar situations.
Also, human eye is notorious in wrongly estimating the bubble sizes (as we have to measure areas). See http://chandoo.org/wp/2009/07/28/charting-lessons-from-optical-illusions/
We can partially improve bubble charts by adding data labels, but if you have too many bubbles, the labels will clutter the chart and make it look busy.
I can't seem to find a way to plot more than ten bubbles on a chart and need to know how to add more
@KW.. why would such a thing happen. I am sure you can add more bubbles that that. Can you tell us exactly what you are doing...
Example table:
A B C (size)
Me: 25 30 15%
Him: 30 22 11%
Her: 12 30 20%
I am trying to make a bubble chart where the Y axis is A, the X axis is B, and the size of the bubble is C. There should be only 3 bubbles. I keep ending up with six (with the labels being only "Me" and "Her"). My goal is to have three bubbles, one representing each person. Clearly I am doing something wrong. Can you help explain...?
Hi,
I wanted to add data labels to the bubbles. Each bubble represents a different company name. Excel allows me to add the size, legend, x axis values and y axis values. How do I add instead- Company A, B, C, D for the bubbles?
youon you have to choice every data for every company..
ex:create bubble for A company,after that click right> add data label> adjust data labels :format data labels and choose : series name.
i hop u will succeed .
[...] we create a bubble chart with 2 bubbles. 1 for the actual mustache & 1 for target [...]
If we want bubble size to be controlled by one column, but the bubble labels to be controlled by another column, how can this be achieved?
many thanks!!!!
