getSymbol().getHovertextTemplate()
It is retained only for GChart 1.1 compatibility purposes.
Prior to v2.4, this symbol drew a horizontal bar from each point to the x coordinate of the next point. Some applications may need to use a revised point set in order to produce the same curves using LINE that they used to produce with this symbol.
See the discussion within the VBAR_NEXT symbol for more information about why
support for these vertically and horizontally constrained
connecting line symbol types was dropped.

As of GChart 2.5, the LINE symbol type will, by default, be rendered with whatever external canvas library you provide to GChart via the setCanvasFactory method.
So now, LINE_CANVAS is just another name for LINE. Please replace LINE_CANVAS with LINE in your code.
Note that LINE only draws continuous lines if fill spacing (setFillSpacing) is 0. With fill spacing > 0, it uses the old HTML-rendering method. Since 0 is now the new default fill spacing for the LINE symbol type, normally LINE works exactly like LINE_CANVAS did. But, if you had explicitly set the fill spacing, you may have to remove this specification, or set it to 0, to get the same behavior you had before with LINE_CANVAS.
Another difference is that you can no longer turn off hover feedback for a pie slice via this method. If you need to turn hover feedback off for a pie slice (or for any other symbol, for that matter) you can use the (new with 2.4) setHoverAnnotationEnabled and setHoverSelectionEnabled methods.
getSymbol().setHovertextTemplate(hovertextTemplate)
It is retained only for GChart 1.1 compatibility purposes.
As of GChart 2.5, the clip-to-plot-area algorithm no longer drops the entire symbol if it's x,y coordinates are outside of the plot area; instead, it clips them off in the traditional "overflow: hidden" manner. Though unlikely you would need to, there is no easy way to recreate the previous behavior.
This change was made so that both rectangular HTML and continuous, canvas-rendered chart elements would be clipped in a consistent and sensible way.
Prior to v2.4, this symbol drew a vertical bar from each point to the y coordinate of the next point. Some applications may need to use a revised point set in order to produce the same curves with LINE that they used to produce with this symbol.
Support was dropped because:
Finally, note that if lines are vertical or horizontal, and solidly connected, LINE automatically collapses them into a single element, so no element-based efficiency losses need be associated with replacing curves using such rectilinear symbol types with equivalent curves rendered via the LINE symbol type.

Please use YGRIDLINE instead.
