Line chart redraw animation type

[Samuel Kelemen]

It is possible to tell graph to redraw lines with "drift" animation when i pass new DataTable to chart? Sometimes it redraws lines with drift but sometimes it only raise points up/down. I am trying to implement slide action with ajax data load and when chart radraws without drift animation users are often lost.

Ok i "hack it", first i add only new points without change viewWindow and redraw chart. After first redraw i redraw chart with all new data and chart animate everytime with "drift" animation.

I was about to suggest the same as you just discovered.  While there is no option to control how the animation is done, you can affect the animation by how you change your data.  There is an optimization that detects when your data has the same number of rows before and after, in which case it does the in-place up/down type of animation, and otherwise, it does the more expensive calculation to find nearest values.  So if you want the latter behavior, just arrange that you only add rows or remove rows, or at least end up with a different number of rows at each step.
