Hi, I have three chart controls chart1,chart2 and chart3. chart1 is line chart. chart2 is bar chart, chart3 is line chart with zoom control.when I update the zoom control in chart3, chart1 & chart2 need to be updated. when I change position of scrollbar in chart3, only chart1 is getting updated,chart2 doesn't update.I have confirmed that callbacks chart1_usercallback,chart2_userbacks are getting called when we change the position of scrollbar, but chart2 is not getting updated. Please help me how can achieve to update chart2 also. Any help will be appreciated. I took Zoomscrollbar sample from chartfx and added bar chart between chart1 and chart3. Thanks in Advance, Janardhan
