Hello, I need help drawing a polar diagram. I need to change something on my diagram. Is it possible to get only the dots and a best-fit curve. I drew in the program paint, how the graph should look like in the following picture. Sorry for my bad english. I hope you can help me. Thanks in advance.
Polar plots create Line graphs by default, but you can change them into Scatter, Line+Symbol or Column graphs if you wish - all will still plot in the Polar form:
Click on the plotted Line in your Polar Plot Click the Scatter button on the 2D Graphs toolbar --> this should turn the plot into Scatter points
There is nothing special about fitting when it comes to Polar Plots. Just select Analysis and pick the type of fitting you want.
