We just released amStock v. 1.1.8.0. [Download]
New features
Stock chart now supports milliseconds.
You can exclude the graph when calculating min and max values for the axis if you set <min_max>false</min_max> for this graph.
Fixed bugs
When all graphs of an axis are hidden, the grid lines and values of the axis dissapear.
Calling removeGraph() does not remove all the traces of the graph. (legend entries as well as Y-axis remains)
When redraw=true chart is resized properly but reverts to original width/height when rebuild() is called.
