Although creating one plot through the Plot Builder is convenient, if you are creating many plots, this can become a tedious way to create the modifications you want. One tip for more efficient graphing is to use the Plot Builder once, and then extract command with all the settings you selected.
In the Plot Builder, you can opt to show the command used to create the plot. This provides a way to learn the way to specify these options directly to the plot command. If you intend to graph numerous similar functions with the same plot settings, this is an efficient way to do it.
For example, here we plot an ellipse using the Plot Builder, and return the command. We then modify the command to plot two additional graphs.
Use the Context Panel to launch the Plot Builder for your expression. In this example, we will graph .
In the Plot Builder panel, select 2-D implicit plot for the plot type. Select show command to see the plotting command. To force the axes to use the same scale, under 2-D Options, for scaling select constrained.
The result is shown in Figure 11.

Now, you can copy and paste this command on a new line (ensure you are in 2-D math mode when you paste it) to create a graph. You can modify the command to create variations. For instance, you can graph or without having to go through the Plot Builder steps again.
1. Graph of , a circle.
2. Graph of , a hyperbola.
