Using the latest.. we are able to get the columns to wrap on the Matrix preview grid.. but it does't save our manualy set column width. If you leave the page and come back the settings are lost. Is there a setting buried somewhere we are missing or is this not in the product yet?
I just verified that I can manually set column width on Matrix preview successfully without this issue in the latest version of Power BI Desktop(2.45.4704.442 64-bit (April 2017)) on my side.
Have you tried removing the original Matrix preview, then add a fresh new Matrix preview to see if it works?
If the issue persists, could you share a sample pbix file which can reproduce this issue? So that we can help further investigate on it. You can upload it to OneDrive or Dropbox and post the link here. Do mask sensitive data before uploading.
We think it should work both ways. We just stumbled upon this because one of our pages has 2 different grids on it with the different configurations. The majority of our reports just have the Rows and Values so we would like word wrap to work in any configuration.
Just to let you all know this has been fixed and will be resolved in a future update 🙂
The 'Values' area of the field well is for the measures you want to see in the matrix. They're repeated for each entry in the fields you put in the 'Columns' area. So, for example, if you put 'Sales' and 'Profit' in the Values area, and 'Year' in the Columns, you'll see Sales and Profit repeated for every Year in your data.
You don't have to put anything in Columns - in that case you just see each field in Values once. That's what you're seeing in your example, and it's where the bug was 🙂
Additional to this - I cant see it referenced explicity in the thread but I have seen a variation of this behaviour which is euqally as frustrating.
Where you have resized columns within the matrix but then click on a column to sort (either deliberately or accidentally!) then the previous resizing is also lost. I have had quite a few annoying experiencing of resizing columns in a big table only for one mis-placed click to lose effort spent formatting it nicely! This especially seems to be problematic around the rightmost column that you try to resize where it is againt the right edge of the visulalisation almost evertime i go to resize this it looses the previous work
