XY graphing problems

[edmiles55]

I am recording current voltage data and plotting to an xy graph. The data is bundled and indexed into an array so that it can be overlaid. The graph should be linear but instead the graph seems to "bounce off the edges" of the graph. The graph seems to have inverted the input data, a sawtooth wave and continually traced out its path. This seems like it would be just a simple graph setting fix.

It says that there's an image attached, but when I read your post there was no image.  Maybe I'm the only one, or maybe there was an error.

The only thing I think that could be from your description, and having not seen a screenshot, is that your y axis is set to autoscale, and you're seeing it bounce around the sawtooth because of its fluctuating value.

If that's not the case, post another pic, or your vi!
