Hi Chris,

the screencast is really amazing. I learned some very helpful tips. Please do others like this one.

Now, there is only one thing that you did not include in your graph (which is a long time doubt I have): the gridlines crossing OVER the bars. I have seen several graphs by Tufte and Phew that show white gridlines crossing over grey bars; I love that! Isn't it possible to do it on Excel?

As for the graph itself, there is one thing I did not like. IMHO, there should be one additional piece of information, something like "probability of death". Not sure if this one would make. My problem is that the graph might be used to say, for example, that prostate cancer has a worrying number of new cases, and deaths might increase. However, since we do not have information regarding old cases to compare to deaths, the simple design might lead us to think deaths will highly increase as a consequence of high number of new cases. Sounds reasonable?

Anyway, thank you very for the screencast.

Nice job Chris. I had to laugh a few times as you were getting some push-back from Excel. Sometimes the first cut is better, or more entertaining, than a polished one... Showing how to format the number so MEN and WOMEN are labeled at zero was very helpful. The NYT did a very nice job setting this chart up. Keep up the great work!

Easier workaround that space guesswork (to centrally align the category labels), Chris, is to add another column where you can put in the number of spaces required; and use the formula =CONCATENATE(REPT(" ",no. of spaces,category label). Some hit and trials will give the result.For a long list / to start with something scientific before hit and trial, here is the solution:
- Figure out the length of longest label(LEN function).
- For each label, use the formula =(length of longest label- length of current label)/2
- Logically this should put in the correct number of spaces in front of each label.. however due to some reason, (may be the width of space character), the alignment seems slightly leftwards. So I add "1" to the formula above.
- In most cases, this would render center alignment. In the skewed cases, one can overwrite the formula with a higher/lower number and achieve desired result.

Wonderful screencast.

Small correction - Apologies.
Read the formula =CONCATENATE(REPT(" ",no. of spaces,category label) as
=CONCATENATE(REPT(" ",no. of spaces),category label)

Great screencast! Thanks for sharing it. I've been using Excel for awhile now but I've never had much of an opportunity to incorporate graphs. When I do, its often a frustrating experience.

Nicely done. Excel graphing masters have their own special kung-fu.

Side note: Assuming you're using a Mac notebook (sounds like it), try using the "fn" key in conjunction with "delete". This should make Windows delete as you expect.

Gridlines over the top is easy if you roll your own using a Line or XY (Scatter) series.

There's a limit to the different types of series that can be combined, but quickly glancing at the design, it doesn't immediately seem to me that you've reached it yet.

A question for you typography experts: what widely-available free font most closely mimics the lettering in New Yorks Times graphics?

Very nice graph, learnt a couple of neat tricks there.

Presuming that we'd be creating this graph to be printed out, or exported as a graphic, I'd be tempted to use either a text box or do something with the camera object here for the series labels.

It might require some altering of cell heights, but I'm sure something could be achieved.

I've only just started making screencasts professionally, but this is one amazing example. Something to look up and aspire to.

For the headline face, NYT is using Franklin Gothic (Bitstream, not ITC); for the body text, Helvetica. Their online features (at nytimes.com) seem to be using Helvetica for all text.

Great screencast.

Nice work Chris. I thought this chart looked sharp when I saw it on reddit the other day. There have been a number of nice graphics and interactive "infographics" coming out of the NYT lately. Any idea what they use to produce these?

Can we look forward to a script/screencast showing how to reproduce this in matplotlib/python?

-Pete

Thanks Chris and Doug. I had a Franklin-a-like already, and I've downloaded the Powerpoint 2007 Viewer to get the new Vista fonts, and used Calibri for a Helvetica substitute.

This is a great tutorial, I learned a lot on this. I've always been turned off by Excel's charts but never spent the time to learn how to make them better.

Wrote it up on my blog too: http://richardsona.squarespace.com

Well done, guys.
I was somewhat intrigued by Daniel Waisberg's wish to have the gridlines OVER the bars. Dereks' suggestion to make a combichart with your own gridlines is one possible solution but I don't think so easy as he said for most of us. I see two possible ways to get these gridlines on top of the bars (although I would like to add that I don't think it's very necessary to do so). I share both ideas here, for discussion purposes.
1. You can use a stacked bar chart with a thin "white" lining around the fill. This requires a bit juggling with the spreadsheet with conditional numbers (for the length of the bars; if it exceeds the default value between the grid values, it needs to be cut off).
Note: I fear this is not easier than derek's suggestion. It also requires some forward thinking about the grid, the default value taken as a variable.
2. An overlay chart. Essentially you split the chart in (a) the bars and (b) the value and category axis, including axes values and grid lines. Make sure the plot area is transparent, and that the dimensions are EXACTLY equal. Now position (b) on top of (a) (Select chart (b) and use ALT+mouse to snap it into position over (a) accurately).
Note: this method is a bit inflexible in the sense that resizing is elaborative. Moreover, in this particular example of a combined chart it may not be so easy to do.

I hope this makes sense.

Well, I meant for someone with the skills to reproduce Chris's graph. At that level of play, the drawing of arbitrary lines over the top usng a XY (Scatter) graph range should be peanuts.

Unfortunately I can't get the Quicktime screencast to work, so I don't know in enough detail how the trick was done to advise how to take the next steps. It would be something like this: create a range of cells with the following values:

<pre>X-value Y-value
-150,000 0
-150,000 12

-100,000 0
-100,000 12</pre>

...and so on. Fix the secondary x and y axis scales to the appropriate values (if they're not already being used for something else--if they are, have a think aboubt designing your way around the problem). Format the line so it is the same as the background colour (white). Now they will only be visible when they cut across the bars.

Build-your-own axis scales (which is very similar to this) is also a highly useful technique; I would go so far as to say it's the most powerful single piece of Excel hackery there is. Both are described in the Juice article "<a href="http://www.juiceanalytics.com/writing/2006/08/tufte-charts-in-excel/">Tufte Charts in Excel</a>" by Zach.

Make sure you install those Windows updates that they were bothering you with during the screencast....

I bet that is a very good illustration of how to produce a good presentation, particularly in a business point of view.

All marketing managers should learn to produce these types of presentations!

<i>Make sure you install those Windows updates that they were bothering you with during the screencast....</i>

They're not bothering me with any updates, either in Opera or Internet Explorer. Both browsers, after taking a long time to download the very large screencast, report:

"QuickTime is missing software required to perform this operation.
Unfortunately, it is not available on the QuickTime server."

I don't see any suggested action arising from that message.

I am not an Excel guru but I did manage to get the grid lines to show through the bars in the graph.

Below is a link to a screen shot of the effect using Excel 2007.

Here is a close up of the chart with both data series using transparency.

Shawn, you're using a feature that is new in Excel 2007, but you've misunderstood the effect that is being sought. It is not to have a black gridline visible under a translucent bar (though there are ways to acheive that effect pre-2007 also).

It is to have a white gridline visible *over* a solid bar, but invisible on the white background. That is acheived by a custom line series, but not, I believe, by built-in gridlines even in XL2007. They're still underneath the data series.

Cool... my recollection of font usage:

AIC Franklin Gothic -heds & subheads, 12pt. (1 col.), 14pts. (2cols.), etc... also used for smaller uppercase (7pts.)

Helvetica & Helvetica-Light: body text (9pts.)
Helvetica-Bold (8-9pts.): bolded upper & lower case text.

Helvetica Light-Oblique: source line (7 or 8pts?)

AIC Imperial: credit (5.8pts?)

I can't get my second graph to flip and display in reverse. It does one of two things:
1. the order of the Y axis values sorts in the opposite order;
2. only one of the data series moves to the opposite side. the one on the secondary axis stays put.

Any suggestions?? Thanks!

That was a great talk! I really liked the slides, the pictures were great and there were some very quotable statements. I think especially the points about reporting vs. analysis and data/analysis vs. presentation were good and are often overlooked. The remarks about BI being a social rather than a technical problem, and about "chart-based encryption" were also spot on: it's unbelievable what visual nonsense is being produced.

Your examples were also interesting, because they were unexpected. NameVoyager and WeFeelFine.org aren't exactly what I would consider business visualizations. But they clearly illustrate what good visualization should do (though they are certainly more on the presentation than the analysis side, which also makes them so appealing: they tell a story, or at least give you the building blocks for one).

What I missed was some kind of big final example at the end that would apply what you said to some real business cases. I am all for visualizing blogs and baby names, but how do these things apply to the typical BI or CRM application? And what does analysis vs. presentation mean in a practical example?

I can't understand business these days.

Microsoft expanded the graphic "blings" in Excel, because business asked for all these realy wierd pyramid columns in pastels. Pastels!! Business asking for pastel colors for presentations??? I thought presentations were to upset the audience, not put them to sleep.

What's the relevance of cows? Is it related to a new advertisong campaign? Analysis is how you can distort the facts to pursuade the audience.If you have to wake up the audience with spectacular displays, why not just bring a wide screen HD tv set and do a surroung presentation with cows mooing in the background (7.1 sound).

You could perhaps have a parade around the perimeter walls of the conference room, with a real brass band. Get everybody to join in. Signifies agrrement with the latest management program.

The slides and discussion really resonated with me. For 10 years I I labored with the presentation of 1,000s of slides to execs about customers and statistics at The Coca-Cola Company, Thursday's discussion finally answered my question, "what am I doing wrong?" The problem was or is a social one. My perspective is changed.

Thank you for providing the enlightenment.

Zach:

Good job.

I'm shamelessly thieving your approach with your PowerPoints and dropped $11 on iStockPhoto to get the appropriately resonating photos for an upcoming conference presentation.

The "chart-based encryption" joke was made funnier since you had no way of knowing if any of the webinar audience "got it." As an East Coaster transplanted west, I've had my share of lines during talks that were pure comedic gold be met earnest non-comprehension . (Another reason we're so well liked...)

Great stuff; I've already dropped the herding cats vs. herding cows distinction on a co-worker.

Please come and give this presentation at my company. I and my coworkers have given similar ones for years now, but they don't seem to carry the same weight as the ones that better-paid outside contractors give.

As an outsider you'll have instant credibility with my senior management, which I and my coworkers lack because we're part of - you know - a cost-center.

To ensure that everything you say to my superiors is taken as seriously as possible, I will disavow any knowledge of having made this post...

[...] I was interested to read what Zack at Juice Analytics had to say on the matter. To paraphrase, reporting is for things we know well and are predictable where as analysis if for things that are unknown and erratic. Now I’ve only looked at the slides (check them out there good!) so I may have missed the context, but that’s not really the point. [...]

interesting presentation. I am especially drawn to the Mindset|Skillset|Toolset paradigm and would be interested in the audio recording, an expansion of these ideas or maybe some reference to follow-up on.

I've always thought that if you provide the tools, the mindset will follow. Sometimes is does and and sometime there's a lot of kicking and screaming.

I'm in an org where the tools are there (multimillion dollar BI/Datamart/Reporting "solution", but the mindset is non-existent and I'm wondering how to overcome this.

The concept of BI as a social problem is compelling and I would like to know more about your thoughts on this.

Great to see that you picked up the idea, and made this challenge around it! Being able to do more than the old pie and bar charts in Excel makes these techniques accessible to a lot more people, and hopefully shows them how much more can be done with visualization than the simple things Excel offers directly.

I agree with some of the comments in the other posting, there are some issues with perception here. Especially when only showing one number, filling the cells from the bottom (like a bar chart) is probably a better idea. However, when comparing several numbers, having areas as square as possible is preferable (squarified treemaps have shown this quite clearly). But this shows that even for simple graphics like this, there is still quite a bit of work to be done to understand how to use them most effectively.

Anyway, great blog, and you have really active readers/contributors!

[...] Nice ways of getting square pie charts. We&#8217;ll have to start using them. [...]

Fantastic. And LOVE the video.

The challenge now is for someone to build in the functionality for showing two different ranges in the same chart.

I answered my own question and emailed in a solution (building on the previous work) that allows multiple values in the same chart. It is also here: http://beglen.googlepages.com/square_pie_DBB.xls

Looks nice, I think this is a terrible chart, for reason as made before, but it does look nice. I could not view the video sadly, in FF or IE :-( - could you put in on youtube?

This excercise flashed my memory back ages ago when someone showed me how to make a squared circle. But that's maths, not Excel.

Surely to show 2 values in the same chart you'll have the 1 colour which is the lower number, then the 2nd colour which is the higher number, the 2nd colour only needs to be stacked ontop of the 1st colour to show the comparitive difference?

[...] Toch lijkt deze uitwerking niet echt een goed alternatief: Optisch lijkt de eerste &#8220;taart&#8221; (of kunnen we deze grafiek beter &#8220;cake&#8221; noemen?) voor meer dan 56% gevuld. Een andere invulling (bijvoorbeeld hele regels van onderaf naar boven) vangt dit wellicht op. Ook het invullen van meerdere segmenten kan onduidelijk worden. Mocht je toch een vierkante taart willen maken in Excel, op Juice Analytics staan enkele in Excel uitgewerkte voorbeelden. [...]
