Using the tool

3. How do I select a new country to look at?

From the home page select a country from the country list.
From the chart page, select your country of interest from the 'Country' drop-down.

4. What data can I view in graph form?

For each country, a drop-down list of data types available is given in the 'category' box. (Please note that new data types will be added during the initial Beta phase.)

You can view the following data (where available):

  • Parliamentary election data - How many votes parties received and how many seats they won by actual numbers or percentages, for parliamentary lower houses and, where available, for parliamentary upper houses.
  • EU election data - How many votes parties received and how many seats they won in European Parliament elections.
  • Presidential election data - Actual vote numbers and percentages for presidential candidates in first and second rounds.
  • Voter turnout figures for each type of election - the actual number voter and turnout (voters as a percentage of the overall electorate).
  • Ministries data - a full roster of the leaders of all cabinet ministries and other cabinet posts identified by name, political party, gender and age and overall summaries of cabinet composition.

Depending on the nature of the data, charts are available both as stacked bar charts and as line graphs.

5. How do I adjust the selection criteria for to get a chart that shows exactly what I want?

Use the 'parties/candidates' tab to select and deselect parties or candidates by name. Deselected parties/candidates will disappear from the graph until you reselect them. Use the 'adjust' tab to select and deselect other criteria:

  • show election results as seats or votes
  • select year range
  • hide or show parties within a certain range of votes or seats
  • hide or show specific ministerial positions

Use the % and # buttons above the chart to toggle between percentage and actual number.
Use the line chart and bar graph buttons above the chart to toggle between these two options (where data permits).

Zoom in by selecting the area that you want to see in greater detail. You can then press the 'Reset zoom' button to zoom out and select other areas of interest.

6. How can I export the whole data set?

You can export the entire dataset for a country by clicking on the 'Export all country data as XLSX' link in the horizontal toolbar at the top. The full datasets are annotated with footnotes (added as 'comments' within the XLSX file) and many country datasets also include additional available information such as referendum results, or local and regional election results.

7. How can I export a partial dataset?

You can export a partial dataset i.e. only the data type you are currently viewing, by clicking on the 'Export this data as CSV' link in the horizontal toolbar at the top.
