Often my work involves processing web page data in excel sheets. This includes extracting the hyperlinks from cell contents. There is no formula for extracting hyperlinks though, you can right click on cell and choose “edit hyperlink” to see which address the cell is linking to. But that is a tedious process especially if you are planning on using the hyperlink for something.

Here is a handy user defined function in VBA for getting hyperlinks from a spreadsheet cell:


Function getURL(forThisCell As Range) As String
'VBA UDF for getting URLs from a cell if any
retVal = ""
If forThisCell.Hyperlinks(1).Address <> “” Then
retVal = forThisCell.Hyperlinks(1).Address
End If
getURL = retVal
End Function


Bonus tip: You can create hyperlink on a cell using “hyperlink()” spreadsheet function. The syntax is simple. =hyperlink("http://chandoo.org/wp","Pointy Haired Dilbert") will create a link in the cell to this blog.

You can sort data across columns instead of rows by changing sort options. If you ever had to sort across columns now you know a simple way to do this

Follow these steps for changing sort orientation:

• Select the table you want to sort (just the data, not the headers as when you change sort orientation, you cannot set header rows)
• Go to Data > Sort
• Click on Options
• Set “Sort Orientation” to “left to right” instead of “top to bottom” as shown below:
  
• Click OK

Bullet graphs provide an effective way to dashboard target vs. actual performance data, the bread and butter of corporate analytics.

Howmuchever effective they are, the sad truth is there is no one easy way to do them in excel. I have prepared a short tutorial that can make you a dashboard ninja without writing extensive formulas or installing unknown add-ins. So get out your shinobigatana and join me in a fresh excel sheet arena.

Before we create our first bullet graph, let us spend a few moments understanding these graphs. Stephen Few proposed bullet graphs as way to provide crisp view of “target vs. actual performance” numbers. Shown below is a sample bullet graph and how you would read it.

Read up more on this at PTS blog and on a Gauge chart that actually works.

Let us create your first bullet graph

Our technique of involves conditional formatting and simple formulas applied to a cell grid. Just follow these 4 easy steps:

Step 1: Prepare your data for charting

Since we are going to plot bullet graphs on a cell grid, we first need to normalize our data. I have chosen to plot each bullet graph on 20 cells in a row as shown in the raw grid shown to the right:

Assuming we have fictitious sales data like this:

You can normalize YTD sales figures using a simple formula like this : ROUND(YTD-sales/target*20,0)

Now that we have our data steaming hot, lets brew the graphs

Step 2: Lets make the raw grid formatted based on data

Now we will take the raw 20 cell grid in each row and conditionally format these cells so that we have background of the bullet graph drawn on them.

For eg. If the normalized sales data for Bad range is 7 and for OK Range is 15 then,

We will highlight first 7 cells lighter shade of gray, next 8 cells gray and last 5 cells with darker shade of gray.

I have shown the conditional formatting applied to these cells below:

When we are done, a sample row looks like this:

We have our cell grids ready now, lets shoot some bullets.

Step 3: Plot bullets on our graph canvas

Our final step involves print a bullet symbol (either – or + or | ) in each cell depending on one of the following conditions:

1. If the cell position (1,2,3 … 20) is equal to Year ago value and cell position is less than YTD value print a + symbol
2. If the cell position is equal to Year ago value and cell position is more than YTD value print a | symbol
3. If the cell position is less than YTD value print a –
4. Else print a blank

See the formula below:

Step 4: Show off your bullet graphs, awe your boss or colleagues, bask in your Ninja glory

Unfortunately, I cannot tell you how to do this. I can only teach you to be a Ninja, but you have to be one to charm people with your tactics.

Shown below is another variation you can try. Also, you can experiment with the symbols printed (instead of + - | you can try other ASCII characters, for more download the excel sheet containing bullet graph templates)

In response to Making Incell charts better article, reader Tony mailed me an excel sheet in which he has modified the charts to display colors and negative values. This is pretty cool. Take a look at the chart below:

MS Excel Incell charts with colors and negative values

The trick lies in displaying the charts in 2 rows, one for positive values and another for negative values and then coloring positive row with green and negative row with red. See aside.

What is your favorite charting trick?

I am fascinated by board games. They provide immense fun, anyone can enjoy them, they are unpredictable and best of all they are great value for money. That is why whenever I get sometime I experiment with simulating games to know them better [read Why Monopoly board game is not as random as it appears]. So, out of curiosity I have created an excel sheet that can generate bingo / housie (housey) tickets - 24 of them at a time. To get new set of tickets you would hit F9 (recalculate).

  Download Bingo / Housie ticket maker excel sheet

Note that these are Bingo UK / India / Australia variant I am talking about, not the US 5*5 type of bingo tickets.

Read on if you want to know how this is done:

According to Wikipedia:

A typical housie/bingo ticket .., contains fifteen numbers, arranged in nine columns by three rows. Each row contains five numbers and four blank spaces. Each column contains either one, two, or very rarely three, numbers:

* The first column contains numbers from 1 to 9,
* The second column numbers from 10 to 19,
* The third 20 to 29 and so on up until the last column, which contains numbers from 80 to 90.

I have removed number “90″ from the list in order to reduce some complexity in generating the tickets.

The problem is now to “generate 15 random number between 1 to 89 and fill them in 15 random spots in a grid of 3 rows by 9 columns such that each row has exactly 5 numbers”

Now I could write a function in VBA to do this, but I wanted to do this only using formulas. So I started breaking the problem.

The first challenge is to select any random 5 cells in a 9 cell row

Once we select any random 5 cells in a 9 cell row, we will fill them with bingo numbers. Now, excel has a function to generate random numbers between 1 to 9 (=round(rand()*9,0)), but this is not good for us since each time we call this function we will get a random number between 1 to 9, where as we need a 5 random numbers without repetition between 1 to 9. The function is memoryless and could repeat numbers when called 5 times.

Instead we can list all the possible “5 cells with numbers and others are empty” combinations of a 9 cells region and select a random combination every time. There are essentially ⁹C₅ i.e. 126 ways in which you can select any 5 cells out of 9 cells (without repetition of course).

So I listed all these combinations in a table and then randomly selected one of the combinations. You can see the first five such combinations in the image below:

Selecting any five cells out of nine cells

Now I created a 3*9 region and filled the cells with 1s or 0s, “1″ when the cell in bingo ticket is supposed to have a value and “0″ if the cell is empty as shown below:

Next challenge is to show random values in each cell

The trick here is that first column in our 3*9 bingo ticket has any number(s) from 1 to 9, second column has any number(s) from 10 to 19 …

Again, the challenge is the numbers should not repeat, otherwise we could simply use rand()*10, rand()*10+10, rand()*10+20 ... to generate the numbers.

This time it gets even more trickier because each column can have either no values, or 1 value or 2 values or 3 values.

The ticket generation logic now looks like:

• If the column has no values in it, then we will leave all the cells in that column of bingo ticket empty
• If the column has 1 value, we will generate any random number from that column’s range of possible values (1-9, 10-19,20-29,…80-89) and place it in the cell that is supposed to have a value and leave other cells empty.
• If the column has 2 values, we will generate 2 random numbers without repetition from that column’s range of possible values and place them in cells that are supposed to have them
• If the column has 3 values, we will generate 3 random numbers without repetition from that column’s range of possible values and place them in cells that are supposed to have them

As you can see, it is easy when the column has no or 1 value in it. But when the column has 2 or 3 I used the combinations trick described earlier.

First I created all 2 number combinations and 3 number combinations. Since the numbers on Bingo ticket are always sorted from top to bottom in a column, I just had to list down 45 combinations (¹⁰C₂) for 2 numbers and 120 combinations (¹⁰C₃) for 3 numbers.

The rest of the details are small enough that I can leave them to your imagination. So when the ticket is generated, it looks like this:

Remember to download housie / bingo ticket generator excel sheet and print your tickets at home. Just F9 to generate new set of tickets. Un-hide the rows from 43 if you want to see how this is done.

I can never get tired of in-cell charts, whenever I get sometime, I try to experiment something on them. Here is an idea to design true incell column charts without using any add-ins or installing fonts. These charts can be fun to have on your project report or annual news letter or memos, they take as much time as munching a handful of M&Ms.

  Download excel chart containing incell bar chart example

1. First we will create in-cell chart using rept() the usual way

This is the simple step. For a sample data, we can use rept() excel function to repetitively print a symbol. Thus, by repetitively printing “|” (pipe) we can create incell bar charts.

REPT() example is shown below:

=rept("|",10) will print ||||||||||

2. Next combine several incell charts to create a column chart

We can combine various incell charts using excel’s concatenate() function or & operator. Better still you can use the concat() UDF. The trick here is we will delimit each chart with an ENTER key code by using char(10) as the delimiter. When used along with “wrap text” cell format this key code will force cell contents to a newline where the char code 10 is inserted.

3. Finally rotate the cell contents by 90⁰ to make the charts vertical

Just select the cell contents, hit ALT+1, and set the alignment formats so that the text is vertically aligned in the cell, and turn on wrap text.

That is all, you will now have an incell bar chart that is vertical like the one below:

Pretty cool eh?

Jon @ Peltiertech has taken a critical look at the partition charts suggested yesterday. You can read his review of the partition charts here. One of the commenters on his site said,

Jon, the partition chart is not that bad. It just needs to be defragmented…

So I de-fragmented my partition chart, this time it no longer provides any spatial trend cues or anything, instead its a cool little replacement for a pie chart, more so when you have just 3-4 pies and got bored of looking at pies.

Here is how in just 3 steps you can do this type of de-fragmented partition chart

1. First create a grid where the chart can appear

This is the easy step, select a range of cells (preferably in multiples of 100, I took 300 cells, spaced over 25 columns, 12 rows) and adjust the row-height and column-width till the range looks fine enough. Take a look at this one on the right.

2. Now set the Conditional Format over the range

Lets say you want to show 3 pies, one for 30%, another for 48% and the last one for 32% (well, just kidding, you can only 110% of your work, not 110% of your pies) so 22%. The conditional formatting formulas can look like this:

Your formulas should look like this:


if cell's row-number * width + column-number is with in pie-1's range, turn the cell on to color-1
else if cell's rownumber * width + column-number is with in pie-2's range, turn the cell on to color-2
else turn the color-3 on


3. Remember to trash your pie charts

Well, not really, save the good old pies. There is no step 3. So I saved you … umm… 33% of work. So why dont you leave a comment and tell me what you think about this ?
