I have added csv file data points into QGIS. Then I opened properties and tried to convert points inside the plot as single line. (used option ---> properties ---> symbology ---> marker--->geometry generator --->Line string) But, I can't see any data in my plot after selecting this option. Is there any other way to convert points to line?
If I understand you the geometry generator is not what you want, basically it's a symbology tool that allow you to use a different geometry on your feature (like representing your point by a polygon buffer for exemple). If you are creative you may be able to create a line with it but the more commun way to convert ordered point to line is by using a geoprocessing tool.
Go to processing toolbox and look for either :
- "Point to path" tool in QGIS>vector creation
- "v.to.lines" in GRASS>Vector
- "Convert point to line(s)" in SAGA>Vector line tools
each of these tool will create a new line layer based on your point
