We often have additional statistical information on our data points, like min/max, standard deviation (error), percentiles, etc.
It would be nice to be able to render at least error bars showing the confidence interval for our data points.
Standard deviation could be provided on a separate column which we could drag into the visual.
It would be nice to have this basic feature in the base product without having to install custom visuals. (I could not find a custom visual for this either.)

RE: Error bars
Error bars would dramatically increase the usability of PowerBI at our institution.
RE: Error bars
An idea for integration would be to use the conditonal formatting pop-up that already exists within tables as a template for error bars as well.
The inability to show uncertainty within the standard visuals is very limiting, but I can see how it would alienate others as well. Hiding them in its own menu would be a good compromise.
RE: Error bars
Very surprising to me that this feature isn't already included! PowerBI already has the data - users should be able to set their confidence interval and have error bars appear on charts.
RE: Error bars
Desperately need this feature!
RE: Error bars
Still waiting, would greatly appreciate if you could add this option to basic charts
RE: Error bars
Need this.
RE: Error bars
Has anyone produced a custom visual that does this yet? This function is really needed when displaying statistical data. It needs to have the ability of entering your own value rather than just calculating SD.
RE: Error bars
Agree this would be good - and something along the lines of how you add them in Excel would work. Someone could create an r visual to do this, but it could be added to the existing bar and line graph visuals.
One approach is already available but it calculates SD rather than allowing you to enter error bar values http://community.powerbi.com/t5/R-Script-Showcase/Bar-Chart-with-Error-Bars/m-p/71763/highlight/true#M55
RE: Error bars
The Excel way would be OK, but we also need to be able to plot a line with a confidence band around it - like the projection feature
RE: Error bars
This would be tremendous. I am constantly working around the absence of confidence bands in other tools. Ideally, I'd like to show a time series with an area (for confidence) and line for predicted/observed as well as a slider/slicer to filter.
