The trick is to use the REPT() function to display the dot plot either horizontally or vertically. Select the data in columns B and C > Insert tab > Scatter Chart. Frequency dot plots We made an add-in for JMP a couple years ago (http://blogs.sas.com/content/jmp/2013/08/21/jmp-add-in-for-statistical-dot-plots/) based on that paper. Instead of using zeros for the dummy series that uses the categories for its X values (the first series in the chart), you would start with three series, plotted as stacked columns, then the dots are plotted on top as above. Instead, they used regular class intervals to produce plots that are similar to the line printer asterisk histograms from way back. It’s a long tradition in statistical graphics going from Tufte back to Tukey and Cleveland to advise against using bar charts. Do you have a team of individuals working together with you to create the dot plot? I’d really love to share it. We will see how we can create a dot plot using 3 data series of some fictitious data.

The chart below show results of a hypothetical clinical trial, where the X values (categories) are three different cleansing approaches, and the Y values are the individual responses, where a lower value indicates fewer incidences of infection. For the sake of this article, we will be considering 2 prominent types of dot plots, namely; the Cleveland dot plot and the Wilkinson dot plot. The result is a set of gray dots added to the chart (below right). I come from the life sciences where Excel is often used to produce these kinds of plots. This freedom is also extended to institutions collecting data plot data for commercial purposes. In excel 2013 every series is changed to xy scatter when you select one series and change it resulting in loss of the catagory lables. The same routines will be helpful to show overlapping points in the “Technical” dot plots in my example above. Step 2: Insert data in the excel sheet.

To select multiple areas, select the first area, then hold Ctrl while selecting additional areas. The chart appears to contain no data, because the zero values produce bars with zero height. The X and Y ranges for each set of dots may be next to each other: or the X and Y ranges for each set of dots may be separated from each other: You also need a small table with the category names and zero values. This kind of dot plot is sometimes called a Wilkinson dot plot. simple histogram binning instead of using methods that follow the rules for the hand-drawn examples. To illustrate how to create a dot plot using Excel, we will be considering the following example. This dot lot was created by Leland Wilkinson. I found the data and am following the protocol, but can’t exactly get the plot in Wilkinson’s paper.

At the time of publishing this dot plot algorithm, he was an Adjunct Professor of Statistics from Northwestern University, Evanston. Excel remembers that the previous added series was changed to an XY type with markers and no lines on the primary axis, so it uses these settings for the new series. These various graph styles are used in data analysis, but the type used for a particular project depends on the goal of the data analyst. The procedure is different depending on which version you have. Dot plots are one of the simplest statistical plots, and are suitable for small to moderate sized data sets. Change the series from secondary to primary axis. The data will have to be counted one by one, which may not be feasible when dealing with a large frequency. I find this inferior, because the dots are unconnected and seem to be strewn across the chart. You can represent a histogram as a line chart, below left, often called a “Probability Polygon”.
