So am trying to create a graph that shows (hopefully) the decrease in our open items over time in a particular project.
Did a search and found a few articles that were for similar issues that suggested creating a two dimensional filter chart, and I have my filter defined but the X-Axis options don't include "Date" or anything similar. How would I create this seemingly simple chart?
As Trudy mentioned, you will probably need a 3rd party app to pull the data in a proper visual format.
There are a lot of reporting options in the Atlassian Marketplace. You can look around the Reports category and do your research.
However, as a Marketing Manager of Custom Charts for Jira, I can show you our solution to the 1 & 2D line charting: https://ossapps.atlassian.net/wiki/spaces/CCFJ/pages/963182593/1D+Line+Chart
You can check the supported fields and assess whether it resolves your issues. Hope it helps! :)
Hello @Kevin Jackey
Welcome to the community.
I don't think you can actually make such a chart with native Jira functionality. Jira does not provide much functionality for making custom line and bar charts. You will need to look into third party apps that extend the reporting functionality.
