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.

Do you have links to any sites that can provide free, large, test data sets. Both large in diversity and large in total number of rows.
Good question Ron. I suggest checking out kaggle.com, data.world or create your own with randbetween(). You can also get a complex business data-set from Microsoft Power BI website. It is contoso retail data.
Hi Chandoo,
I work with large data sets all the time (80-200MB files with 100Ks of rows and 20-40 columns) and I've taken a few steps to reduce the size (20-60MB) so they can better shared and work more quickly. These steps include: creating custom calculations in the pivot instead of having additional data columns, deleting the data tab and saving as an xlsb. I've even tried indexmatch instead of vlookup--although I'm not sure that saved much. Are there any other tricks to further reduce the file size? thanks, Steve
Hi Steve,
Good tips on how to reduce the file size and / or process time. Another thing I would definitely try is to use Data Model to load the data rather than keep it in the file. You would be,
1. connect to source data file thru Power Query
2. filter away any columns / rows that are not needed
3. load the data to model
4. make pivots from it
This would reduce the file size while providing all the answers you need.
Give it a try. See this video for some help - https://www.youtube.com/watch?v=5u7bpysO3FQ
Normally when Excel processes data it utilizes all four cores on a processor. Is it true that Excel reduces to only using two cores When calculating tables? Same issue if there were two cores present, it would reduce to one in a table?
I ask because, I have personally noticed when i use tables the data is much slower than if I would have filtered it. I like tables for obvious reasons when working with datasets. Is this true.
John:
I don't know if it is true that Excel Table processing only uses 2 threads/cores, but it is entirely possible. The program has to be enabled to handle multiple parallel threads. Excel Lists/Tables were added long ago, at a time when 2 processes was a reasonable upper limit. And, it could be that there simply is no way to program table processing to use more than 2 threads at a time...
When I've got a large data set, I will set my Excel priority to High thru Task Manager to allow it to use more available processing. Never use RealTime priority or you're completely locked up until Excel finishes.
That is a good tip Jen...
