You can control which issues or projects are not relevant for chart you want to render and remove them using filters. At the moment, the combination of the following filters can be used:

A simple example below shows how filtering works. You can see two filters being active: Status and Component. Numbers right before filter name are indicating how many statuses, components etc. had been matched. In this case, there's one status that match ("In Progress") and one component:

Active filters

Another example, with all the filters removed. Issues EP-2 and EP-6, previously removed, now are rendered in appropriate places:

Filters disabled

Affected vs Fix Versions

 

"Version" filter works against both "affected" and "fix" versions. Therefore, if an Issue has two versions assigned, for example, one as "affected version" and another "fix version", both these versions need to be checked on filter's dropdown list to have such Issue rendered on the chart. For more sophisticated filtering scenarios, JQL can also be used.
