I have a question about guide.

Hi. everyone. My name is H.Nam from Korea.

I have a question about guide.

when I execute my guide project source file using F5 button, the images and graphs from previous work are still remaining!

I didn't execute any command, but the results from last work are still remaining.

When I clicked 'lumen detection', the problem occured.

Since then, the data from last work has appeared when I execute the guide project file.

the function only contains 'getline' function.

I want to remove them. please help me!
