Bar and donut charts of your Jira issues, grouped by any field including your custom ones. It reads the whole result set, and tells you when it couldn't.
Jira's search API hands back one page at a time. A chart gadget that asks once and draws what it gets is drawing the first 50 or 100 issues and labelling it with the name of the whole query. Nothing on the chart says so. The bars have the right shape, the legend is right, the title is right, and the total is wrong.
That is the worst kind of wrong, because nobody double-checks a chart that looks fine. Somebody reports "we have 43 open bugs" in a planning meeting, and the real number was 430.
This one walks the whole result set and says on the chart whether the count is complete. If a query is too large to finish in one refresh, it tells you how many issues it did read instead of quietly drawing a tidy picture of the first hundred.
It is careful about that word. A Jira search can be curtailed by an app access rule or a query limit and still return a perfectly normal-looking response, so the chart reports on what Jira returned for your query, and drops the completeness claim the moment Jira warns it was cut short. That is a narrower promise than "exact", and it is one we can actually keep.
Status, assignee, priority, issue type, components, labels, sprint, and every custom select, version and user field on your instance. Fields that cannot make a category, like free text and timestamps, are left out of the list rather than offered and then producing one bar per issue.
It never writes to your Jira. The only permission it asks for is to read work, which you can check on the install screen before you agree to it. Charts run as you, so a gadget never shows anyone an issue their own permissions would hide.
It fetches nothing from anywhere. No external scripts, fonts or images, and no charting library: the drawing is done by the app itself. Counting a large query still takes as long as Jira takes to answer, and the gadget says "Counting issues" while it waits rather than showing you an empty box.
