How do you use PlotLegends in Mathematica?

To use PlotLegend, you first need to load the Plot Legends Package using Needs[“PlotLegends`”]. PlotLegend->{text1,text2,…} assigns text to each line in the same fashion as PlotStyle. PlotLegend also enables Plot and related functions to accept options for Legend, which will modify the legend produced.

How do you plot a circle in Mathematica?

Actually, there is a special command in Mathematica that can be used to plot circles and ellipses: Circle[{x,y},r] gives a circle of radius r centered at {x,y}. Circle[{x,y}] represents a circle of radius 1.

How do I run a Mathematica code?

If you just want to execute code from Mathematica source files in your project, you can do this by opening a notebook from the project, and loading the code into Mathematica. For example, if you created a basic project Test, you can open the notebook file, Test. nb, and then load and use Test.

How do you plot data in Wolfram Mathematica?

The Wolfram Language offers extensive support for plotting all kinds of data in many different ways.

  1. Consider the following data to be plotted (stored as sdata):
  2. Use ListPlot to plot sdata:
  3. Plot sdata by filling to the axis:
  4. Use ListLinePlot to plot sdata with a connecting line:
  5. Plot sdata and cdata together:

How do I add a legend to a plot?

Set the DisplayName property as a name-value pair when calling the plotting functions. Then, call the legend command to create the legend. Legends automatically update when you add or delete a data series. If you add more data to the axes, use the DisplayName property to specify the labels.

How do I open Mathematica on my desktop?

To Launch Mathematica: From the Start menu, choose Programs ▶ Wolfram Mathematica ▶ Mathematica 12. Alternatively, you can open an Explorer window, go to the Program Files\Wolfram Research\Mathematica\12.0 directory, and double-click the Mathematica icon.

How does plot work with decimals?

So it warns you that it is turning approximate decimal values back to exact rationals, finding the solution and then passing that back to Plot which then turns those back into decimals and displays your curves. which first finds the exact solutions and then hands those solutions to Plot.

How does plotplot work?

Plot initially evaluates f at a number of equally spaced sample points specified by PlotPoints. Then it uses an adaptive algorithm to choose additional sample points, subdividing a given interval at most MaxRecursion times. Since only a finite number of sample points are used, it is possible for Plot to miss features of f.

How to plot in three dimensional spherical coordinates in AutoCAD?

To plot in three dimensional spherical coordinates, use the SphericalPlot3D command. It willtake a function of r, q, f and plot it in spherical coordinates. First, a sphere of radius 1 is plotted as : SphericalPlot3D[1, {q, 0, p}, {f, 0, 2 p}]

What is the use of expressions in plot?

PlotLegends ->”Expressions” uses the f i as the legend text. Plot initially evaluates f at a number of equally spaced sample points specified by PlotPoints. Then it uses an adaptive algorithm to choose additional sample points, subdividing a given interval at most MaxRecursion times.
