Awesome chart to visualize Salary Increases for 3,500+ people [Tutorial]

Game for some charting awesomeness?

Off late, I have been doing a lot of data analysis and visualization on performance ratings, salary hike, gender pay equality etc. Today let me share you an awesome way to visualize massive amounts of data.

Scenario: Your organization of 3,686 people recently went thru annual performance ratings & review process. At the end of it, everyone was offered some salary increase (from $0 to $24,000 per year). You have 7 business groups. How do you tell the story of all these salary hikes in one chart?

How about the one above?

Employee Performance Panel Charts – Excel vs. R [video]

Recently, I had to make a bunch of panel charts. After wrangling with Excel (and a tiny bit of VBA) to create them, I wondered if we are suffering needlessly by being too loyal to Excel. I switched to R and could create these panel charts in almost no time (well, first I had to learn how to pivot the data using dplyr). Today, let me share the experience.

Start your bar charts from zero – Excel geeks screaming at you from mountain top

Here is a simple but vital charting rule.

Start your bar (or column) charts from zero.

To illustrate why you should do this, let me share a personal example.

Over the weekend, the Jon Peltier visited Wellington. He is staying with Jeff (who occasionally guest blogs on Chandoo.org). On Sunday, we all decided to hike up a small mountain near my house for a leisurely family picnic.

While on the top of the mountain, Jo (my wife) took a few pics of us three Excel geeks.  As we were standing on a sloping mountain face this is how the pictures look.

Looking at the picture on left, you would confidently say that I am way shorter than other two. But picture on right tells a different story.

Modelling Inventory Run Rate & Cash Flows using Excel

Imagine you run an office furniture company. You want to stop reordering two brands of furniture – Relaxer (a type of chair) and Boca Top (a type of table). You currently have 20,000 Relaxer chairs and 5,000 Boca Tops. These are valued at $200,000 and $100,000 respectively. When sold, they will yield $100,000 and $25,000 gross profit. You are hoping to sell them off in 2 or 3 years. You forecast that we can sell off these as per some yearly schedule.

You need to analyze this and prepare a cash flow model.

Let’s learn how to answer such open ended questions using various analysis techniques in Excel.
