With a cross tab matrix that has a lot of row fields, the matrix has a horizontal scroll bar enabled, but for some reason the scroll does not function in either the Desktop or Online tools.
This is not a perfect solution but a good work around
You can increase the size of the sheet to include all the table .
Bellow link explain how to do it
I think we figured out what's happening. It looks like Power BI is treating the matrix 'rows' like 'freeze panes' in Excel. I.e. all the variables you put into the 'rows' (which actually become columns in your matrix, but lets not go there for now) are fixed and not scrollable because they are frozen. If you put variables into the 'values' part of the matrix, these then become scrollable.
But only the 'values' will be scrollable, not the rows (which are frozen).
This is a shame. In my line of work (healthcare) we frequently use many columns of categorical data for statistical analysis, and its pretty crucial to be able to see your data in column format. Categorical data doesn't really work in the 'values' section of the matrix visualisation.
EDIT - I think this description actually echo's what WillT says above. The terminologies used are really confusing (for me anyway). Microsoft call the columns in a matrix 'rows', and 'values' are also columns but they appear to the right off all the other columns ("rows").
+1 experiencing this problem.
Vertical scrolling works in a matrix, but horizontal does not.
"when you have enough row groups in a matrix so that they don't all fit in the viewport, the scroll bars are disabled. This is because scrolling normally only affects the values area of the matrix."
Not sure what this means. Why would you disable scroll bars if your data doesn't fit in the viewport? The entire purpose of scroll bars is to show data that doesn't fit in the viewport.
Showing the data as a table does remedy the scrolling problem, but it's an unsightly way of presenting data that has repeating values in a column.
Agreed, not sure what the upside of not allowing this would be. The matrix display is so much better, but the ability to scroll horizontally is vital. Why even create it if you are going to leave out such an obivous feature. Please fix ASAP, there are so many of these formatting quirks out there that might seem trivial to a software designer but can absolutely ruin a project. Spending hours trying to google a workaround is not an efficient use of my time.
The point about choosing a default location on a scrollbar is also a must implement.
I encounter the same issue..
By choosing a table, the problem is partially fixed: horizontal scrolling works, but the visual representation of the info/data is clearly different.
I have many data points in the rows for product charterstics that we need to display. I cannot scroll to see the data. It would be nice to choose where to freeze the view.
