ZedGraph Scroll Event
In One of my Project,I have two Zedgraph in the one Window Form.I am loading data in the Graph,for both zedGraph ,Making AutoScroll is True.
if i move Left or Right the Horizontal scrollBar of the First Graph,then the Graph of the First is moving on the move of Fist Horizontal ScrollBar move.Now i want to develop same effect on the Second Graph on the Move of First Graph Scrollbar move.Code of my Project is Below:
