Plot disappearing

Development
1

I wrote custom plot which derives from vtkPlot and added it to vtkChartXY.
When i zoomin at some point the plot just disappears.
I looked at vtk sources and found that the problem originates in function vtkChart::CalculatePlotTransform:

for (int i = 0; i < 2; ++i)
{
    if (fabs(log10(origin[i] / scale[i])) > 2)
    {
        /* the code here looks strange, when i got here the plot disappears */
        shift[i] = floor(log10(origin[i] / scale[i]) / 3.0) * 3.0;
        ^^^^^^^^
        shift[i] = -origin[i];
        ^^^^^^^^
    }
....
}
