Blixt Wipes out screen

I use C++ CodeBlocks.
I made a program which accesses an A/D collects data and plots it. I used the render function to create my screen and graph axes. I can plot my data, but I can't seem to label my axes. I tried blixting to a rect with the label made as a bmt with paint. The update function places the label, but clears the screen so I only have the label and no graph.
