I also see a LOT of personal preferences driving vertical vs. horizontal decisions. Today, let’s check out how lots of small edits–small deletions, in this case–add […]. Ann K.

Emery | Removing Redundancies from My Old Graphs, http://annkemery.com/avoiding-diagonal-text/, wanted to display some key demographic characteristics, We also used a population pyramid to compare the distributions of males and females, we needed to display the proportion of hospital procedures (“Product A” and “Product B”) that were performed by this hospital (“the ABC Org”), we needed to display how many people agreed or disagreed with each statement on a survey, we needed to make a one-page handout that summarized whether program participants were more knowledgeable about New England history, Martha’s Vineyard, or whaling after completing an educational program at a museum, Re-envisioning a University’s Monthly Report: Two Reports with Two Different Purposes. We chose to give the timeframe more weight than the scaled survey responses. Bar diagram can be horizontal or vertical, where a horizontal bar graph is used to display data varying over space whereas the vertical bar graph represents time series data. Copyright © 2020 | All Rights Reserved | Web Design by. This is a particularly effective way of presenting data when the different categories have long titles that would be difficult to include below a vertical bar, or when there are a large number of different categories and there is insufficient space to fit all the columns required for a vertical bar chart across the page. Great, logical way to think about it. Let’s look at a few examples. Data visualization best practices, practical how-tos, tutorials in multiple software platforms, and guest experts. 331. It’s a small detail that gets viewers a bit closer to the numbers. Your email address will not be published. I also see a lot of inconsistency within documents. Transform your reports with these practical tips. Let’s look at a few examples of horizontal bar charts and vertical column charts from real projects. I tend to prefer bars, probably because I’ve seen too many smushed columns with diagonal text. Bar graphs are the pictorial representation of data (generally grouped), in the form of vertical or horizontal rectangular bars, where the length of bars are proportional to the measure of data. do_vertical_align( jQuery( '#f-post-el-49' ) ); do_vertical_align( jQuery( '#f-post-el-26' ) ); do_vertical_align( jQuery( '#f-post-el-36' ) ); Most “professional” reports are too long, dense, and jargony. One question: Do you have a reason for including the axis/scale on all of these charts, in addition to the data values presented with each bar/column? However, it is also possible to draw bar charts so that the bars are horizontal which means that the longer the bar, the larger the category. Then, within those columns, we displayed the ordinal survey responses. Graphs exist to showcase our numbers so I want graphs to subtly remind viewers whether numbers are ordinal, categorical, etc. We also used a population pyramid to compare the distributions of males and females. Another name for ordinal variables is sequential variables because the subcategories have a natural sequence. I chose horizontal bars over vertical bars because I arrange ordinal variables from left to right across the page. More consistency means readers spent less time interpreting the graph (and therefore have more mental energy left to actually think about the implications of the data and act on it). Horizontal Bar Graph. Agree/disagree scales are ordinal. I see a lot of vertical column charts where the labels are so close together that the text gets twisted diagonally (http://annkemery.com/avoiding-diagonal-text/), which takes our brains longer to read than plain ol’ horizontal text. Grouped bar charts can be used to show several sub-groups of each category but care needs to be taken to ensure that the chart does not contain too much information making it complicated to read and interpret. The information could also be presented in a series of pie charts. This is a good way to present data with long labels that would be hard to display below a vertical bar. My answer: It depends on what type of variable you’re graphing. civic amenity sites) and these are usually coloured or shaded differently to distinguish between them. Let’s pretend they’re scores on an academic exam that range from 0% to 100% correct. Pre-post comparisons are comparisons over time… and time is an ordinal variable… so we selected vertical columns. […], […] I display patterns over time from left to right across the page.
