Using a tooltip with a LineSeries with an Logarithmic Y-axis, seem to give widely inaccurate results.

The series is as follows:

double[] x = new double[] { 1, 1.0e1 , 1.0e2 };
double[] y = new double[] { 615.9, 275.6197, 11.05376};

Using a CursorModifier as follows:

<s:CursorModifier ShowAxisLabels="True" UseInterpolation="True" SnappingMode="CrosshairToSeries" ShowTooltip="True"/>

The expected behaviour would be for the Crosshair to follow the curve, but for some reason it’s some way off. It looks as if it’s following Y-values which are somewhat truncated. X-values are fine for some reason.

Is there are a way to increase the resolution of the Y-values so the user gets the correct value when using a tooltip.

    I updated to the latest v6.3.0.13476, but the problem is still there. I also tested the nightly build v6.3.0.13542 which also has the issue.
