To filter by label,

1. Click on the cog on the top menu of your widget.
2. When the edit page appear, click on the advanced tab.
3. Select one or multiple labels.
4. Press save.

You can select by story types this way. You will find the bug, feature and chore within all your labels. While selecting your labels, we apply a OR logic between them. Selecting multiple labels means that a story will appear if it has <label1> OR <label2> OR <label3> and so on.
