Coming all the way from France is the developer GeeckoDev and his new plotting tool gPlot++. This nifty little app will allow you to plot and display 4 concurrent functions and will allow you to move them about as needed through zoom and panning. gPlot++ comes loaded with functions and could be an easy replacement for your graphic calculator if you're in a pinch.
