Here is where we learn that the third bar from the right is "100x" and the short bars on the left are in the range of 200 - 300.įor a graph to be effective, pattern perception and table look-up have to tell the same story they have to be fully complimentary. Table look-up is where the user reads the labels and axes to gain a quantitative understanding of the data underlying the graphical display. So pattern perception tells us that the third bar from the right is biggest the smallest bars cluster on the left half of the graph some bars are darker than others and there's some extra labels over them etc. When a person reads a data graph, they are performing two distinct operations: what Cleveland calls "pattern perception" and "table look-up." Pattern perception happens first and is an interpretation of the geometric arrangement of the graph (relative distance, size, position, etc.). I do like, however, that you used shades of color rather than different colors to do the highlighting people often forget that a sizable portion of their audience will be unable to see distinctions based only on color. Highlighting the three bars helps to bring the viewers attention to them, but does not fix the underlying problems with the graph design. TalKohlberg (#39) It's always fun to discuss such matters and see new approaches thank you for the opportunity. Your comments are a testimonial to what our community is all about. Alas, there is no native support for dot plots in excel and you have to do some bit of circus to get them right.Īgain, thanks to Naomi, Tom, Christian, Rajdeep, Dan, Hui, Sanford, Nimesh, Mark, David, Bill, Michael, Jason Sanford and all others for sharing what you think about this issue.
(5) Dot Plots: I think these are even better than bars.
#Ms excel y axis break full
You should go thru Jon's tutorial on full axis split in excel here:
#Ms excel y axis break how to
(Good work by Tom showing how to get full split thru R). I was too lazy to work out the mechanics of complete split thru excel. axis split: I agree with Naomi that it has to be a complete split. profits etc.) But if you have been using this approach and your readers already know it, then you are golden. Usually secondary axis works best when you have 2 diff. (3) Secondary Axis: While this approach is creative, I would avoid it as it can be confusing. Of course, if I want to make a chart for the above data alone, I would rather go out and party as the sales skyrocketed during holidays. The data set I used is almost meaningless. Tables: My intention in this post is to discuss how we can chart when data has wild ups and downs. Your audience need to be in right mindset to digest logs. I have never really seen a log axis graph that is effective outside scientific publications. Thank you for thoughtful discussion Naomi.
Related discussion on forums – Lots of small values but few extreme values – how to present it?Įxcellent points everyone. How do you go about charting then? Share your ideas and implementations using comments. But I am sure you get such data once in a while. I seldom deal with data that has this kind of outliers.

Go ahead and download it here:Įxcel Charting options when you large and small values What would you do? I have put all these 4 chart examples in a workbook so you can see the underlying technique. Let the bars reach sky: You can of course, set axis max to an arbitrary value, just so that all the small values are clearly displayed and let the higher values literally cut thru plot area. Read broken y-axis to know how to do this.Ĥ. I have used 2 charts and aligned them neatly. Split the axis in to two: This is the most trickiest technique. Use log scale for vertical axis (axis option > check logarithmic scale)ģ. Now, how do you go about making a chart?Ģ. That is, you have data like the numbers shown to right, with a surprising bump during Christmas time. How do we effectively plot all of them in a chart? We have a lot of small numbers and a few very large numbers. Here is an interesting charting problem we come across once in a while.
