Increase resolution of numbers shown on axis.

I am currently following the tutorial at the page listed here.

https://wordpress-931910-4332701.cloudwaysapps.com/documentation/win/current/webframe.html#Tutorial%2003b%20-%20Adding%20Series%20to%20a%20Chart%20with%20MVVM.html

Instead of using the given values to add to the series, I am using very small values like so:

var lineData = new XyDataSeries<double, double>() { SeriesName = "Testing Series" };
lineData.Append(0, 0);
lineData.Append(1, 0.001);
lineData.Append(2, 0.002);

However the axis ticks do not display a high enough resolution as shown in the image attached. Each one will show either 0, 0.001 or 0.002 and no further. I have tried changing the axis MinorDelta and MajorDelta to smaller values but this has not worked. Is there any way to fix this?
