Multiple curves using ZedGraph

I have a strange thing happening while using ZedGraph.

I am using the same item to add multiple curves. Like:

ZedGraph LineItem curve_3;
curve_3 = pane.AddCurve("", xx_1, yy, xxyy);

I call the above lines multiple times to add multiple points. But when I remove the curve, only the last added curve gets removed and left all stays on the pane.

this.zedGraph_RenderedTrack.GraphPane.CurveList.Remove(curve_3);

I am not finding a way that will clear all the curves added. Is there a to do it?

My actual requirement is that I have to add the different lines dynamically on the pane, but I don't need to display the label information and all of them should be plotted by a single click and removed by a single click.

You are holding only the last curve in this code:

ZedGraph LineItem curve_3;
curve_3 = pane.AddCurve("", xx_1, yy, xxyy);

Use collection like List<LineItem> to remember all the curves.

List<LineItem>.foreach(r => this.zedGraph_RenderedTrack.GraphPane.CurveList.Remove(r);
)

If you want to remove all curves from your graph pane, simply use the CurveList.Clear() method:

this.zedGraph_RenderedTrack.GraphPane.CurveList.Clear();
