DevExpress.XtraCharts图表如何不显示线条的标签，或者使用SwiftPlot的时候，如何显示多轴？

[cnwolfs]

如下图，如何把这些密密麻麻的标签去掉，和原点去掉，同时把线条变细。

或者，在使用SwiftPlot的时候，如何实现多Y轴显示？

找人解决问题啊

设置 SeriesBase.LabelsVisibility 的属性

稍微详细点好吗，我怎么找不到SeriesBase.LabelsVisibility ，我当前用的是11.1.6的版本，麻烦给点代码 DevExpress.XtraCharts.Series mSDisplacement = new DevExpress.XtraCharts.Series("流量", DevExpress.XtraCharts.ViewType.Line);

     DevExpress.XtraCharts.Series mSDisplacement = new DevExpress.XtraCharts.Series("流量", DevExpress.XtraCharts.ViewType.Line);
                mSDisplacement.Label.Visible = false;

搞定了，多谢，明白的就是这么简单

            DevExpress.XtraCharts.Series mSDisplacement = new DevExpress.XtraCharts.Series("流量", DevExpress.XtraCharts.ViewType.Line);
            mSDisplacement.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Numerical; //X轴的数据类型
            //mSDisplacement.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;//显示字符串的参数，必须设置类型为ScaleType.Qualitative
            //((DevExpress.XtraCharts.PointSeriesView)mSDisplacement.View).PointMarkerOptions.Kind = DevExpress.XtraCharts.MarkerKind.Cross;
            ((DevExpress.XtraCharts.PointSeriesView)mSDisplacement.View).PointMarkerOptions.Size = 1;  //改圆点到最小值，就不画圆了
            ((DevExpress.XtraCharts.PointSeriesView)mSDisplacement.View).Shadow.Visible = false;
            //((DevExpress.XtraCharts.SeriesBase)mSDisplacement ).View.
            mSDisplacement.Label.Visible = false;//去掉曲线区域的label显示

            DevExpress.XtraCharts.Series mSFlow = new DevExpress.XtraCharts.Series("累积流量", DevExpress.XtraCharts.ViewType.Line);
            mSFlow.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Numerical; //X轴的数据类型
            //mSFlow.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;//显示字符串的参数，必须设置类型为ScaleType.Qualitative
            ((DevExpress.XtraCharts.PointSeriesView)mSFlow.View).PointMarkerOptions.Size = 1;  //改圆点到最小值，就不画圆了
            ((DevExpress.XtraCharts.PointSeriesView)mSFlow.View).Shadow.Visible = false;
            mSFlow.Label.Visible = false;//去掉曲线区域的label显示

还有个缺点是线条太粗，这个以后再处理了

你Y轴的那个流量名称怎么显示的啊，是那个属性啊。求给代码。谢谢。
