I have followed the dynamic series documentation found here https://docs.mendix.com/howto/extensibility/charts-dynamic-series. Instead of the data source using the database i have created a microflow to get the data needed. When i run my project and set a break point in the data source microflow the breakpoint is never hit. I have selected the dynamic option on the data source tab for the Series Item, selected a microflow that returns a list of Value objects and selected the series object in the dynamic series tab. Is there something else that needs to be done to allow the microflow to be called?
Have you seen the test project? There should be a sample for each chart in this project.
