ZedGraph AxisChange() 重置？

发布于 2024-09-13 20:56:16 字数 154 浏览 6 评论 0原文

我正在使用 C#。当我使用 AxisChange() 调整图表上的轴时，它工作正常，直到我进入图表窗格并手动放大和缩小。

手动放大和缩小后，AxisChange() 命令不再起作用。如何获得它以便在轴固定后，您可以再次使用 AxisChange() ？

我检查了 AxisChange() 方法的代码，我认为这是因为以下代码：

            // if the ChartRect is not yet determined, then pick a scale based on a default ChartRect
        // size (using 75% of Rect -- code is in Axis.CalcMaxLabels() )
        // With the scale picked, call CalcChartRect() so calculate a real ChartRect
        // then let the scales re-calculate to make sure that the assumption was ok
        if ( _chart._isRectAuto )
        {
            PickScale( g, scaleFactor );

            _chart._rect = CalcChartRect( g );
            //this.pieRect = PieItem.CalcPieRect( g, this, scaleFactor, this.chartRect );
        }

但我不确定，您应该在“if”子句之外尝试复制行...并看看会发生什么。不管怎样，尝试调试源代码，就足够理解了。

I've checked the code of AxisChange() method and I think this is because of following code:

            // if the ChartRect is not yet determined, then pick a scale based on a default ChartRect
        // size (using 75% of Rect -- code is in Axis.CalcMaxLabels() )
        // With the scale picked, call CalcChartRect() so calculate a real ChartRect
        // then let the scales re-calculate to make sure that the assumption was ok
        if ( _chart._isRectAuto )
        {
            PickScale( g, scaleFactor );

            _chart._rect = CalcChartRect( g );
            //this.pieRect = PieItem.CalcPieRect( g, this, scaleFactor, this.chartRect );
        }

I’m not sure though, you should give a try copy line … outside the “if” clause and see what happens. Any way, try to debug the source code, it is good enough for understanding.
