NPlot is a free charting library for .NET which should handle what you are looking for (and a whole lot more). It'll handle the resize for you automatically when set up properly. Go here for the download and here are some examples of what it can do. The download itself also comes with a few tutorial projects demonstrating what it can do.

Simply add a reference to the NPlot.dll from your project and then add a PlotSurface2D to your form. Set the AutoScaleAutoGeneratedAxes property of your plot to true

plotSurface.AutoScaleAutoGeneratedAxes = true;

then each time you add a new data point to the plotSurface, the axis will automatically resize for you.
