*UPDATE* The Power BI Update team has resolved this problem. To read about how Power BI Works now, check out my blog post Time to Use Custom Visualizations in Power BI.
After looking at some of the neat custom visualizations with Power BI, like the fish or something like the synoptic panel, I was sold. Time to start using these neat visualizations in my reports in Power BI. I rather regret the decision. Why? I’ve provided my reasons here.
Warning Messages Every Time the Power BI Report is Viewed
Neither I nor the client is interested in seeing a message which looks like something sketchy is in the report. Reports are supposed to answer questions not leave people wondering what is wrong every time they look at the report. The message looks like some kind of a legal cover just in case the code is really bad. Worse the report is broken as the visualization will not show until the yellow button is clicked. Yes I can click on the button and the message will go away and look like the first report image shown above with the fish, but not for long. Like this meme, the message will never go away forever, but appear every time I or someone else opens the report.
Good Luck Getting Rid of the Custom Visualization in Power BI
If you were smart enough to add the custom visualization to the Power BI using the Power BI Desktop, you are in luck. I don’t have that kind of luck. I loaded it to the web application. Why does it matter where you loaded the visualization? Because you can’t get rid of it in the web version. Check out this link from Microsoft and scroll down to this part “Once you import a custom visual you cannot remove it from the report.” Even when I got rid of any use in the report to the custom visualization the link to the custom visualization is still there. The warning message never goes away. If you added the custom visualization to Power BI Desktop, you are in luck as Teo Latchev has posted instructions for you to get rid of the visualization in Power BI Desktop. It’s not a straight-forward process, but at least there it is possible.
So Long and Thanks for All the Fish
Until I have the ability to change my mind with design issues, which I though was sort of a prerogative, I’ll be staying away from custom visualizations. If I can’t turn the warning message off, I probably will never use custom visualizations. Hopefully you will read this before you had to do what I did, deleted the report and started over.
