ZedGraph AxisChange() Reset?

Question

I'm using C# When I use AxisChange() to adjust the axis on my graph, it works fine, until I go into the graph pane and manually zoom in and out.

After manually zooming in and out, the AxisChange() command no longer works. I was wondering how you can get it so after the axis get fixed, you can again use AxisChange(). Thanks!

Answer 1

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.
