I am, like everybody these days, trying to make a real-time dashboard for a IOT peice of hardware. This is shockingly hard to do for as popular as it is.
I am using Temboo to stream data via azure to powerbi. This is working great! However, there are some limitations in PowerBi that I can't seem to understand. To the point where I feel like I just must be doing something wrong. They are:
1. I have streaming data being plotted against a timestamp, but can't chang the limits of the axis in any kind of relative way. IE, I can't have a plot show the last 24hr of data. I can only have it show a specific time range of data. Is there a way to either tell it to show a certian count of the data, or setup a user feature that sets the filter? That would be something like a slider at the bottom that lets user zoom in as they like.
2. I can't filter based on the last reported data. So if I want to show the most recent datapoint sent to Powerbi I am out of luck. This would be usefull overall to be able to see the current value of some input. But I can't seem to figure out how to do that.
Those are the two biggest issues. I can imagine a solution where I sent other data from my hardware that tells powerbi what to show, but that would be not ideal. Before I do that, I wanted to just ask if anybody had already figured these things out.
