## Polar ChartA polar chart is essentially an XY plot drawn on a circular grid, showing trends in values on the basis of angles. Like logarithmic scales, polar charts are useful primarily in mathematical and engineering applications. In a polar chart, the independent variable (X) is charted on the angular axis. By default DPlot draws the origin (zero point) at three o'clock. The dependent variable (Y) is charted on the radial axis, with the origin (by default) at the center of the circle. As an example we'll walk through recreating the polar chart appearing on the Features page: This graph plots the function r=abs(sin(3φ)), where φ is the
angular value. Select Enter the values shown above: "abs(sin(3*x))" for the function, from X=0 to 360 degrees. This initially results in a normal XY plot with linear scaling on both the X and Y axes. Right-click on the plot and select "Polar Coordinates" to get a polar plot: Note that when using To instead select degrees, right-click on the plot and select See also: |
