c# - How to do aligned scrolling through two chart areas without using AlignToChartArea? -

-

i have 2 chartarea objects in chart (system.windows.forms.datavisualization.charting i'm using).

one point graph, , other rangebar graph. horizontal axis on rangebar graph y axis, cannot use this:

chart1.chartareas["chart area 2"].alignwithchartarea = "default";

i've figured out how zoom both charts , keep them aligned, when try scroll both charts clicking on scrollbar on 1 of horizontal axes, can't quite line up. almost line up, they're off maybe second or (the horizontal axis in both graphs time).

here's have:

private void thechart_axisviewchanged(object sender, vieweventargs e) {     if (e.chartarea == thechart.chartareas["mypointchartarea"])     {         thechart.chartareas["myrangebarchartarea"].axisy.scaleview.position = e.newposition;         thechart.chartareas["myrangebarchartarea"].axisy.scaleview.size = e.newsize;         thechart.chartareas["myrangebarchartarea"].axisy.scaleview.sizetype = e.newsizetype;     }     if (e.chartarea == thechart.chartareas["myrangebarchartarea"])     {         thechart.chartareas["mypointchartarea"].axisx.scaleview.position = e.newposition;         thechart.chartareas["mypointchartarea"].axisx.scaleview.size = e.newsize;         thechart.chartareas["mypointchartarea"].axisx.scaleview.sizetype = e.newsizetype;     } }

what else need charts line up? physical extent of charts same. it's data misaligned.

thanks help.
