When using the RadHTMLChart ScatterLineSeries with data that straddles January 1st, 1970, it seems that by default the Y axis crosses the X axis at 1/1/1970. If all of the data precedes 1/1/1970, the Y axis crosses the X at its maximum value.
When using a date axis with a databound ScatterLineSeries, how can I ensure that the Y axis always crosses the X axis at its minimum value?
To see an example, simply replace the relevant C# code from the Date Axis
demo page with this:
dt.Rows.Add(1, 2, new DateTime(1969, 06, 12));
dt.Rows.Add(1, 5, new DateTime(1969, 12, 12));
dt.Rows.Add(2, 6, new DateTime(1970, 06, 17));
dt.Rows.Add(3, 4, new DateTime(1970, 09, 18));
dt.Rows.Add(4, 7, new DateTime(1971, 03, 18));
I have tried setting the XAxis.MinValue and XAxis.AxisCrossingValue properties to either zero or (decimal)minValue.ToOADate(), but it either has no effect, or causes all points before 1/1/1970 to render incorrectly - the chart begins at 12/31/1969, and all points before that date "crowd" the axis.
