It seems spreadsheets & dinosaurs on a collision course. How else can you explain Jon’s XKCD Velociraptor problem solved with Excel and now this. Debby, an alert reader of our blog sent me this email yesterday.
I need an algebraic formula to solve this in Excel
I have 5 heads, 5 bodies, 4 arm sets, 4 leg sets and 3 tails. I need to see if I can create 1000 dinosaurs from these, and if that’s too many AND I need the 5 digit groupings to prove it and create them.
basically Xa*Xb*Xc*Xd*Xe=1000 – I’m not supposed to go over 1200. […] And then I want the 5 digit combinations if possible – right now they are trying to do the combinations by hand – would be awesome if we could do it in Excel.
Ladies & gentlemen, let’s fire up Excel
There are two problems to solve.
(1) How many dinosaurs can be made?
(2) Listing of all such dinosaurs.
The first one is easy.
We just multiply the number of heads, bodies, arms, legs & tails. I know this sounds biologically impossible. But in math everything is possible. So we get =5x5x4x4x3 = 1200
That means, given the body part variations, we can generate 1,200 dinosaurs. Some of them may be hideous, but 1,200 of them nevertheless.
Making 1200 dinosaurs in Excel
This is very simple. We just use the MakeDinosaur() formula in Excel.
Of course, I am kidding. There is no MakeDinosaur(). Instead, we can use the all powerful INDEX().
Let’s say, we have listed the various parts in a range like this:
Now, each of those ranges are conveniently named as heads, bodies, arms, legs and tails.
Next, in an empty column, we list 1200 running numbers. Side note: we could do away with this step and use ROWS() function. But dinosaurs don’t mind helper columns.
Let’s say, these running numbers are in H4:H1203.
We now use our T-rex sized INDEX formula.
=INDEX(heads,(H4-1)/240+1) & INDEX(bodies,MOD((H4-1)/48,5)+1) & INDEX(arms,MOD((H4-1)/12,4)+1) & INDEX(legs,MOD((H4-1)/3,4)+1) & INDEX(tails,MOD((H4-1),3)+1)
This generates all combinations of dinosaurs.
Let’s dissect the t-rex. Shall we?
- The formula is a concatenation of five INDEX functions.
- Each fetching one body part viz head, body, arm, leg or tail
Head portion:
Formula: INDEX(heads,(H4-1)/240+1)
What it does? There are 5 head choices and 1200 possible dinosaurs. That means, each type of head is attached to 240 (1200/5 = 240) dinosaurs.
So, we simply take the number in H4, divide it with 240 and figure out which head to use.
Body portion:
Formula: INDEX(bodies,MOD((H4-1)/48,5)+1)
What it does? So we now have 240 possible dinosaurs with a given head. And we have 5 types of body. That means 48 dinosaurs per each type of body given a head type.
We could use INDEX(bodies, MOD(H4-1,240)/48 +1) to get the corresponding body number.
Alternatively, we can use the simplified version INDEX(bodies,MOD((H4-1)/48,5)+1)
Why does it work? That is for you to figure out. There is a reason we are not extinct yet.
Remaining parts:
We use similar logic to fetch other body parts.
Download the dinosaurs
Download the 1,200 dinosaurs. Be careful, #14321 is a bit loony. She almost bit my shift key.
How would you make ’em dinosaurs?
Of course, we could use VBA, other formulas to make these nasty reptiles. What would you do if someone asks you create a few dinosaurs? Share your recipe in the comments.

8 Responses to “Top 5 keyboard shortcuts for Excel Charts”
As far as I remember (checked, again, 2 minutes ago) in my "Excel 2013" in order to select various chart elements I need to use the Arrow keys and not the TAB key.
Practically, the TAB key does nothing (within a Chart).

Thanks for pointing this out. This is how I remember it too, but when I was recording the video yesterday, only TAB key worked. MS must have changed the keys in Excel 2016. I have edited the post to include both keys.
The key navigation on charts is different in 2016.
TAB cycles through a layer of objects (SHIFT+TAB cycles backwards)
ENTER move down a layer
ESC moves up a layer
So on a column chart with title/legend/data labels if you select the plotarea the TAB will go through Title > Legend > Plotarea.
ENTER at plotarea will then select Vertical axis. Tab will take you through
Horizontal axis > gridlines > Series > Horizontal Axis.
ENTER with series selected will then allow you to TAB through individual data points and data labels.
If you ENTER on datalabels you can TAB through each data label.
ALT + F1 : to create default chart
ALT+E S T = CTRL + ALT + V, T : I find that easier to remember
I second what Michael already said about TAB and arrow keys. I can't help but think if this is related to the "," or ";" as separator. I prefer to use the chart tools - layout- drop down box, anyway.
Got to be F11 for instant charting. Highlight your data , hit F11 and voila! ?
Ctrl+1 is the most important chart shortcut. In fact, it works for any Excel object: whatever is selected, Ctrl+1 opens the task pane or dialog to format that object.
Somewhere along the line, maybe when Excel 2016 came out, the arrow keys stopped working to cycle through the elements of a chart. But what works is holding Ctrl while clicking the arrow keys. I haven't gotten used to the Tab and other keys, but as long as Ctrl+Arrow works, I'm good.
And F4 used to be so helpful when formatting a lot of charts. But since Excel 2007 came out, it has been mostly useless. It used to remember a whole set of changes at once, so I get that the newer modeless dialogs make that impractical. But now it only seems to work with formatting of lines and borders, and maybe fills. I find myself writing a lot of VBA one-liners in the Immediate Window to handle these tedious formatting tasks.
after clicking on a chart, is there a shortcut key to copy it?
Thank you for the Alt E S T - tip. This is more than a time saver. Because of dynamic charts or de-activated external references to data when you make the charts, you often have empty charts that are otherwise impossible to format. So this shortcut helps adressing that. I will work with it more and see if there remain some obstacles.
