Questions & answers:
I don’t see the Issue Matrix panel in an issue where I expect to see it. How can I troubleshoot this problem?
If you are unable to see the Issue Matrix panel in an issue where you expect it to be, you can troubleshoot the problem using the Preview feature. Follow these simple steps:
Note down the issue key of the specific issue where the panel is missing.
Go to Project Settings> Apps > Issue Matrix Configuration.
Find the relevant matrix in the list and click Edit.
Scroll down to the Preview section and enter the issue key of the specific issue.
The Preview feature will show a message explaining how to fix the problem.
How are long column headers or long content in a column visualized in the Issue Matrix panel?
The matrix table takes all the space of the left column in the issue view page (usually around 1000px wide in 1440p resolution) and tries not to show any horizontal scrollers.
When multiple columns (10 or more) are configured, they will be very narrow. The reason is that Issue Matrix will try to show them all in its panel without resorting to a horizontal scroller. This means that values like 100% for the column width in the Issue Matrix configuration will have no effect.
The column width value in the configuration serves as a minimum value for the width of the column (if possible). Suppose the configured value is too small, but the column's content is too large. In that case, Issue Matrix will expand the column to display the entire range of the field. Truncating or displaying the value over the next column is not the desired user experience.
The table header is also considered when expanding the column width. If you specify the column to be narrow (e.g., 10px), but the header contains words extended further than that value, the column will be expanded again to display the title correctly. You may try renaming a column to make it narrower.If a column needs more space according to the above rule, it may expand and occupy some of the space of the other columns. That means some columns will be narrowed (even if they have a bigger width value in the configuration) to display the other columns. Each column has a minimum width of about 16-20px (so that there is enough breathing space between columns), so setting smaller values in the configuration will have no effect.
