Use the X location property to specify the number of pixels from the edge of the chart to the left edge of the chart element. Use the Y location property to specify the number of pixels from the edge of the chart to the top of the chart element. Set X and Y to -1 to allow the chart to automatically position the element.
These properties are located on the Location node, found on the ChartArea, Titles, Legend, and ChartLabels nodes of the Visual Studio Properties window.
