Description

With Wt 3.3.5-rc2, an interactive WCartesianChart sends a complete update with the next event after a client-side zoom or pan. Depending on the timing of incoming events, this can revert a client or server side change to zoom/pan values. An attached test program (with additional notes) demonstrates the issue.

A patch that seems to help with the issue is also attached for your review; it has had only limited testing.
