Issues with x/y axis in Recently Created Chart

[TimothyK]

We recently upgraded our version of JIRA to 7.2.7 and we are now seeing issues with our recently created issues charts.  The XY Axis are showing wingdings and other symbols making it very difficult to read the charts.

Please take a look at the KB: JIRA UI shows unreadable text or nothing on CAPTCHA and some gadgets due to missing fonts

This is a known issue that can effect some linux/unix operating systems that Jira might be running on.  Basically it boils down to some specific font packages could have been removed/uninstalled by operating system updates.   The KB has steps you can take to reinstall the packages that Jira is expecting to be present.  This should fix the problem, but if it does not, please let me know.
