Merlin – Do a bit of magic in Merlin reports – PART XX

Those of you who have checked our new post series about “Merlin report templates” know by now…

Now let’s do some magic with the reports.

Work Chart

If you like to report  expected or actual working hours per resource in a chart and/or table, this is a custom report doing so.

You may check contained ‘’, “WorkChart.wbl” to see how we iterate in project’s master resources, ask for their working units, compare them with total work hours and output this information in the table. In the pie chart, working hours are forwarded and the pie chart calculates respective percentages. There are methods in the Python part gathering the x- and y-Ticks and some javascript functions drawing the graph. You may furthermore disable outputting resources’ work in the table and define the first 8 colours to be used for the pie chart.

Feel free to modify this custom report further as you require for your needs.

An output sample:

Showing expected work hours by resource.


And the report options:



  • Extract the zip first
  • place the contained mrept package under the following path of your mac: ~/Library/Application Support/Merlin/Reports
  • (in case you have no “Reports” folder please create it first and pay attention to name it exactly as “Reports”)
  • restart your Merlin and
  • call File > New Report… to find the new report called “Work Chart”.
