Circular statistical graphic | pie
By Eric Melse | Feb 16, 2022
This post shows how to include a Stata pie chart into your report. First, for this example some fictional data is entered that is used to create a circle diagram, a circular statistical graphic that is divided into slices like a pie or pizza (Smith 2017).
* Preliminaries net install cleanplots, from("https://tdmize.github.io/data/cleanplots") replace set scheme cleanplots clear all * Load the example dataset (manual input) input sales marketing research development sales marketing research development 12 14 2 8 end label var sales "Sales" label var market "Marketing" label var research "Research" label var develop "Development" * Use the first asdocx command and create the MS word file, after that, * asdocx adds results to this file asdocx, text(Example of using a pie graph in asdocx) fs(12) /// font(Arial) save(Example_asdocx_graph_pie.docx) replace asdocx, text(\par) append * Include a pie graph to MS Word using asdocx asdocx, text(Figure 1. Pie graph example using scheme cleanplots (Mize 2021).) asdocx graph pie sales marketing research development, /// plabel(_all name, size(*1.5) color(white)) xsize(4) /// ysize(4) legend(off) plotregion(lstyle(none)) /// title("Expenditures XYZ Corp.") subtitle("2020") /// note("Source: Financial Report (fictional data)") append pagebreak(after) * Include a pie graph to MS Word using asdocx asdocx, text(Figure 2. Pie graph example using own colors.) asdocx graph pie sales marketing research development, /// pie(1, c("244 189 0")) pie(2, c("255 201 14%70")) /// pie(3, c("98 176 255")) pie(4, c("98 176 255%70")) /// plabel(_all name, size(*1.5) color(black)) xsize(4) /// ysize(4) legend(off) plotregion(lstyle(none)) /// title("Expenditures XYZ Corp.") subtitle("2020") /// note("Source: Financial Report (fictional data)") asdocx clear // finally, delete stored files
The file created by asdocx can be accessed from here Example_asdocx_graph_pie
The first graph looks like this.
The second graph that uses own color is shown below.
Pie charts are extensively used as a business graphic, typically in annual reports. However, for statistical usage the pie chart is criticized by many on the one hand (data-to-viz, Hamberg), as well as defended (Aleksejeva 2015, Emery 2015, Few 2007, O’Reilly, Viguier 2018).
Whatever your position on the subject might be, should you need it, asdocx does support the inclusion of a pie chart.
Also note that a better alternative for the pie chart might be the so-called donut chart, which is created starting from a pie graph and then using Stata’s graph editor (Musau 2021).
