What errors do you mean? In the console there are no errors related to this.
If you are using a single the same microflow for the series, than it is expected that each series will have the same result…..
Maybe add an image of the settings of the widget…
To see my new microflow refer below –
the graph is same for both the months? Whereas it should be different depending on the data so entered. I tried building another microflow for the same. It still shows same result for both months despite data being different?
