OriginLab continues to add support for map analysis and map-based charting, something that has been a focus for the last several versions. With our newly-released Origin 、 OriginPro 2022b, we have added a new “Bar Map” graph template that plots a simple column or bar chart at user-specified geographic locations, on an easily-added map background.
View a video: “Create a Bar Map Plot” on YouTube.
The “Bar Map” template will plot either as a column chart or a bar chart depending on your preference (Plot Details > Map tab > Orientation group) and you can use controls on the same tab to set column/bar width and height.
The same data can just as easily be plotted as a “Pie Map” — with a pie chart replacing the column or bar chart. In case you missed it, pie maps were added in the previous version, Origin 2022.
What do I need to get started?
Bar maps and pie maps share a common and straightforward data requirement:
- Longitude and latitude coordinates (designated as X and Y, respectively) for a number of places of interest — cities, countries, etc. Most longitude values will be on a -180 to 180 scale but Origin’s world map can work with a 0 – 360 scale, as well.
- Two or more designated Y columns containing measurements of some quantity of interest. These columns should contain measurements that you want to compare/contrast for each of your longitude and latitude coordinate pairs.
- Once you’ve plotted your Y columns against your longitude and latitude pairs, you’ll use the Insert menu to add a map background (Insert > World Map/Map of China/Continental US, etc.).
- You can also plot over an imported GeoTIFF image, as in the case of the “Protein Consumption” map in the opening paragraph. Adding a GeoTIFF background is not complicated and is demonstrated in one of the Origin 2022b sample projects available by pressing F11 and searching the Learning Center Graph Samples tab for 2022b.

If you don’t already own Origin or OriginPro 2022b and would like to try making your own bar or pie map , you can download a Trial version of the software and obtain a license to evaluate the software for 21 days.
