To-see a readout of polar plot coordinates of the specific points that make up a trace, follow these steps: • Click in the polar plot to select it. • Choose Graph-e. Trace from the Format menu to show the Polar Trace dialog box. • If necessary, reposition the Polar Trace dialog box so that you can…
Mathcad provides several ways to help you to identify what it is you’ve plotted. You can display: • A title centered above or below the polar plot. • A legend identifying each trace. • The arguments you used to create the plot. The relative locations of each of these labels on a perimeter graph and on a…
Mathcad uses default settings to format the axes and traces of new polar plots as you create them. You can change these defaults in two ways: • By saving as defaults the settings of your current plot. • By using the Setting Default Formats for Polar Plots dialog box to set defaults, if.” you don’t want…
You can reformat the traces on your polar plot, using the Traces page of the dialog box for formatting polar plots. To reformat a plot’s traces: • Click in the polar plot to select it. • Double-click in the polar plot. Alternatively, choose GrapheePolar Plot from the Format menu. Mathcad displays the dialog box for formatting polar…
Just as you can graph several expressions on a single Cartesian (X- Y) plot, you can graph several expressions on the same polar plot. Each expression generates a trace. A polar plot can show several r expressions against the same 8 expression, or it can match up several r expressions with corresponding 8 expressions. To graph several r…
Mathcad sets the upper and lower radial axis limits by default. For a linear scale, the upper limit is the maximum radial value of whatever is plotted. The lower limit is zero. For a logarithmic scale, the upper limit is set to the next higher integer power of ten above the maximum of the data. The lower limit…
You can reformat your polar plot’s axes, using the Polar Axes page of the dialog box for formatting polar plots. To change a polar plot’s format: • Click in the polar plot to select it. • Double-click in the polar plot. Alternatively, choose Graphee-Polar Plot from the Format menu. You’ll see the dialog box for formatting polar…
Creating a polar plot Mathcad’s polar plot operator lets you plot functions that do not lend themselves well to Cartesian (x- y) coordinates. A typical polar plot shows the value of a radial expression r versus an angular expression e. For example, you could use a polar plot to graph circular antenna patterns or electric field intensities around…
