Changes

The PyPlot window has a number of controls that let you change the settings of your graph using your mouse. For example, using the Pan/Zoom button {{[[Image:Py_zoom_icon}}]], you can pan the graph with the left mouse button and zoom it in or out with the right mouse button. A combination of the two operations usually gives you an ideal scaling of your graph. As you move the mouse on the graph, you can read the value of the horizontal axis (X) and the corresponding value of the total electric field distribution along the X direction. You can also customize the graphs and change the scale of the graph axes. Click the {{key|Graph Settings }} button and uncheck the Auto box. Enter values -4 and 4 for <b>Min </b> and <b>Max</b>, respectively, for X-Axis and set the <b>No. Major Intervals </b> to 8 in "Axis Settings" panel. Similarly, for Y-Axis enter values 0, 5, and 5 for <b>Min </b> and <b>Max</b>, and <b>No. Major Intervals </b> respectively. <table><tr>
