ZoomCharts Documentation

When enabled, a tooltip is shown for every visible comment marker, anchored above (or below) the marker. When disabled, a tooltip appears only while hovering a marker and follows the mouse cursor.

How chart comment markers resolve overlaps with each other.

• default: bottom markers use moveup, top markers use movedown, and markers with {@link SettingsComment.iconMarkerOffset} keep an exact position (none).
• none: markers always draw at their layout position (may overlap).

Controls which comments appear in the side panel.

• visible (default): comments whose marker center, shape endpoint, or (when there is no marker) data-item bounds intersect the chart.
• allLoaded: every comment from data currently loaded at this level.
• allAtLevel: every comment for the current aggregation/drilldown level, supplied by {@link panelItemsFunction} (not limited to currently loaded chart data). Falls back to allLoaded when the function is missing or returns null/undefined.

App-provided source of side-panel comments for {@link panelContents} === "allAtLevel". Should return every comment that belongs to the current aggregation/drilldown level. Chart markers are unaffected and still come only from loaded data.
