I have a c# form which is to allow the user to specify a differential
equation (dy/dt = -lambda*y) to solve (see below for rest...)

both exactly and approximately (by entering desired values of the intital
condition, time step and lambda into textBoxes). zedGraph is then used to
graph the exact and approximate solutions. The problem is that the label
and textBox for timeStep (which I added after adding the zedGraph section)
and the 'draw graph' button are superimposed on the graph, partially
obscuring it. The textBoxes and labels for lambda and the initial
condition were added o the program before the zedGraph part and don't get
superimposed. Is there a way to stop the timeStep label and textBox
frombeing superimposed without having to write the program again and
adding the textBox before the zedGraph section?
