Update your support docs
Each time I try to find an answer about how something works in your support articles they are overwhelming vague and ultimately useless for troubleshooting.
For example, I am now trying to configure a dashboard card and I have read everything you have written in your support forum about cards and dashboards and there is no useful guide to how to set up the axis and manipulate the graphs. I think you should try to put more explanations in for how the charts, fields and categories behave and how to set them up. I don't find this intuitive to use at all so some good documentation would save so many frustrations.
My suggestion is that when you get users submitting questions you should consider that it is something that should go into the guide. If I have to ask you the question of how something works I'm very sure there are other confused people out there.
