LogarithmNumericTicksProvider is causing overflows during zoom and pan

Aug 14, 2009 at 4:43 PM


  I have created a chart with logarithmic Y axis. When ever I am zooming and panning, at this point of code, I am getting overflows

  private double[] CreateTicks(Range<double> range)

// Code snipped

   int count = (int)(maxUp - minDown + 1);

   var ticks = new double[count];

The value of the cound is invariably a large negative number. So any ideas how to fix this? Looking forward for the logarithamic axis make the cut to the  stable version. Thanks for the great component.

I am having the same trouble with the latest checkout 28448

You should be careful with logarithmic axis - if Viewport.Visible rectangle somewhere crosses zero or has a subrectangle in negative area, it will throw an exception, because of data domain of logarithmic function, which is broken in such situation.

What value of Viewport.Visible did you have?




Aug 31, 2009 at 3:30 PM



  it is fairly in the negative region :). Is there any way I can force the viewport.visible to stay in the positive region?

I'm still having this problem.

When the range comes into the CreateTicks, it is 4.9E-324 - Infinity

How is this calculated?

None of my Log values are next or near 0

When I've used logarithmic axis the latest time, I wrote the following:


<d3:ChartPlotter Name="plotter" Domain="{x:Static d3:DataDomains.XPositive}">

Domain is a property of Viewport, it is a rectangle which limits possible values of visible area.

And to set visible area in data coordinates, I used the following C# code:


var genericPlotter = plotter.GetGenericPlotter();
genericPlotter.DataRect = new GenericRect<double, double>(9, 0, 110, 2);

Best regards,

I am having similar issues. With Mikhail's suggestion, zoom and pan functions are now fixed; however, an exception still occurs when I double-click on the graph. Any workarounds for that?

Also, the first three ticker x labels (my log scale is X-axis) are all zeros on my plot. After that, correct log scales are displayed. Is this also a known issue?

Moreover, I am seeing 2 legends on the plot even though I only plotted one curve. How can I get rid of this additional legend?

All above issues are happening in the latest Nightly build from Dec. 12 v0.3.4703.0.

Any update on these issues will be very useful. If I double click on the plot then it crashes. I was able to get around the other problems i.e. 2 legends and x-axis showing zeros but not the crashing issue.

Also, in log10 x-axis mode, I have 2 plots one on each y axis and they share the x-axis; however, the second plot seems to be squished together. I think the 2nd plot starts from where the first plot ends.

If you are back from your vacation then please help me with these issues in D3 LineCharts.

Hi Faisal,

Sorry for making you wait.

What value of Visible property is in your program that causes described behavior?

What value is returned by plotter.GetGenericPlotter().DataRect?

Edited Feb 17, 2010 at 4:02 PM


No worries. I am so glad you are back.

plotter.GetGenericPlotter().DataRect returns: {(1,0) - (10,1)} i.e. XMax=10.0, XMin=1.0, YMax=1.0, YMin=0.0

Value of Visible property is 'Infinity, Infinity, NaN, NaN' and it is crashing in Viewport2D.cs line 227:

    set { SetValue(VisibleProperty, value); }

Here is the detailed execption trace:

Hi Mikhail,

Were you able to fix this issue? This happens frequently if you zoom out too much and then try to zoom back in using the middle mouse wheel.
