I have made UltraChart based on pixels.How I can get the X-axis point on based of the pixel position?
I'm not really sure what you're asking for. Area you trying to map screen coordinates to the chart's axes for drawing a custom shape? If so, need to handle FillSceneGraph event. You can find an example here:http://help.infragistics.com/Help/NetAdvantage/NET/2008.2/CLR2.0/html/Chart_Modify_Scene_Graph_Using_FillSceneGraph_Event.html
