I'm sure you have searched plenty http://stackoverflow.com/questions/1917798/ms-chart-control-change-the-order-of-series-in-a-legend[^] I don't know the complexity of your chart, but I do know that the order in which you load the series to the chart is important, and what type of chart you select as well such as a series chart with plot lines. I guess take a pie chart, now you have a legend to explain the pieces of the pie, there really is no order to it. Unless the largest pieces of the pie down to the smallest are the order. I've always had to experiment for hours to get them right, and after 100's of them, narrow down which charts to stay away from. I'm not sure if you can do multiple legends, and display them in rows or columns. Not the answer you want, but your going have to take to pencil and paper and record your results based on what you get, or try the Microsoft Forum for Chart Control at asp.net
