Multiple panes enable the Chart to be divided into stacked horizontal sections, each with its own axis and dataset while sharing a common X‑axis. Add multiple panes to a Chart by defining them within the ChartRows collection using the ChartRow component. In this sample, monthly precipitation is displayed in the top pane, while average temperature is visualized in a separate pane below using a secondary Y‑axis. The secondary axis is added to the ChartAxis component, and the RowIndex property of the axis assigns it to a specific pane. Additionally, a series is explicitly bound to its corresponding axis using the YAxisName property. This layout allows different units and ranges to be compared clearly without visual overlap.
