1.9

Changes from 1.8

• Many additions and fixes in HitTest for lines and points charts both in 2D and mainly in 3D modes.
  #39, #40, #41, #42.
• Optimizations and bugs fixes (including #35).

Breaking change.

The algorithm for determining indexed series has been changed. Previously, a series was considered indexed if the IsXValueIndexed flag was set or if all its data points had an X-axis value equal to 0.
To draw a vertical line at an X-axis value of 0, you had to set a custom flag, IsXAxisQuantitative.
Now, a series is considered indexed only if the IsXValueIndexed flag is set. The custom flag, IsXAxisQuantitative, has been removed. This change also improves performance, especially for series with many X-axis zero points.

Recommended actions:

• If your indexed series were defined solely by having all their X-axis values equal to zero, you need to set the IsXValueIndexed flag for these series.
• If you were using the IsXAxisQuantitative flag, you should remove it.
