Popup Chart Formatting
Currently, the popup chart has very limited set of formatting options. For example the biggest missing option is that the chart doesn't show the chart labels nor does it give you the option to change/format the labels.
Furthermore, you can't change the position (left right center), format (font etc.) and location (top bottom) of the title and/or caption.
It would be nice to have these features in AGOL 🙂
I have the same issues. There really should be at least axis formatting available, otherwise the information is hard to communicate. Better title and caption formatting options would also be very nice. ArcGIS Pro is able to do this, but the formatting doesn't carry over to web maps.
One thing that was not mentioned is a way to format the mini-popup when hovering over the chart. It would be nice to be able to add units and choose whether or not to include the field name in the popup.
