This exception is raised if you do not provide X xalues for the data points or Series.IsXValueIndexed is set tot True. In both scenariou logarithmic scale is not supported.

你应该也是中国人吧。。。我也遇到了相似的问题，在代码中合适位置加入2句话应该就好了：

            chart1.ChartAreas["ChartArea1"].AxisX.IsLogarithmic = true;
            chart1.ChartAreas["ChartArea1"].AxisX.IsStartedFromZero = false;//大部分错误可能就是因为没加这句话

为了好看起见，可以再加入适当的间隔，比如：

            chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Interval = 5;
            chart1.ChartAreas["ChartArea1"].AxisX.Interval = 1;
