Issue: When hovering over a donut or pie chart, the tooltip only displays the numeric value but does not show the label name (e.g., "Solar Only", "Solar + Battery", "3rd Party PV"). Only the number appears, making it difficult to identify which segment is being hovered.
Expected Behavior: The tooltip should display both the label name and the corresponding value when hovering over each chart segment.
Chart Type Affected: Donut chart, Pie chart
