Panning error in Log axis with Absolute Min/Max

Dears,

I found one issue when it applies Log axis with Absolute Min/Max values, Panning should be blocked with those absolute values, but when I tried the panning, the chart showed wrong range of values and graph was disappeared.

I think I found the cause of this as below, but I'm not sure how I can apply this modification on you main source tree, so, after reviewing this I would appreciate it if you could apply this change on your main release.

in "LogarithmicAxis.cs"

    public override void Pan(ScreenPoint ppt, ScreenPoint cpt)
    {
       ...
        if (newMaximum > this.AbsoluteMaximum)
        {
            newMaximum = this.AbsoluteMaximum;
            //Original Code
            // newMinimum = newMaximum * this.ActualMaximum / this.ActualMinimum;

            // New Fix
            newMinimum = newMaximum / this.ActualMaximum / this.ActualMinimum;
        }
    }

Regards,
Ian Ryou.

Thanks for reporting the bug!
I think the correct code should be

newMinimum = newMaximum * this.ActualMinimum / this.ActualMaximum;

I am submitting the updated source code now. I have also included an example model that can be tested in the example browser.

For future bug fixes:

• create a fork
• create an example/unit test that I can use to verify that the fix is working
• submit a pull request
