Now my question. What is the easiest way to represent the data in a time series chart?

For some reason I had a similar problem with NPE and charts in 8.2.2


If you use a persistable entity to store the data in it should work 


Hello everyone, hello phil and Merry Christmas.

The children are in bed and sleeping. When I passed my home office, I had an idea, changed the microflow and got the following result :)



Yes!!!! :)

But I do not know exactly if this is the right way, because the browser freezes after about a minute ..

However, there are also 3 x 9400 data sets, since I have been saving the weather data every 10 minutes since mid-October. That is a lot of data for such a visualization

I wish you all a Merry Christmas :)


I think you can use line chart and put this microflow inside, for the left you may choose what value to display.


Hello quang nhat tran, 

thanks for your answer. Unfortunately I always get the same error.

“Microflow should have on parameter of type wetterdaten.Dashbord”

I've tried a lot now. but unfortunately I can't figure it out. But when I display data directly from the local mendix database everything works great. It is apparently due to the non-peristable entity "SelectResultWetterdaten". The data for this entity are generated from the microflow. What am I missing? I am thankful for every help.


Merry Christmas

Andreas :)
