Origin Ver. and Service Release (Select Help-->About Origin): b9.5.1.195 Operating System: windows 10 Hello I can not select some of contour lines like these. Beside, when i click on a specific contour line a contour that is away from my selection will be selected. For example, i clicked on the inner contour bot the displayed contour was selected. Could you please help me to solve it. I have attached a picture from my problem. Thank you very much.
If you zoom in the graph, will it be easier to select?
It looks there are 5 layers. Are they overlapping and it happened that there is plot in other layers that's closer to where you clicked? You could try right click 3 icon and choose Show Active Layer only and try the selection.
BTW, for contour lines, there are multi-selection mode. 1st single click -- select the plot 2nd single click -- select all contour lines with same value 3rd single click - select contour lines at the location
