Make the changes you desire, and close the Graphics Inspector. (the pointed should change when you hover over an element) Press Ctrl + g to open the Graphics Inspector. Here’s a plot highlighting the region satisfying both sin( x) < y and x < π/2:īetween Show, options like GridLines and Epilog, and all of Mathematica‘s built-in graphics functions, you have a lot of flexibility when creating custom visualizations.Ĭlick here to download this post as a Computable Document Format (CDF) file. The border should change from orange to thick gray. ![]() For example, RegionPlot can be used to visualize regions satisfying inequalities. You can use Show to combine the graphics produced by any of Mathematica‘s graphics functions. The advantage of ContourPlot is that you can readily visualize more complicated relations than x = π. Labels and callouts can be applied directly to data and functions. (Note that Show uses the plot size and axes of its first argument-in this case, the regular plot of sin( x).) The Wolfram Language provides a rich language for adding labels to graphics of all types. Using the function Show, you can combine the contour plot with a regular plot of sin( x): Instead of manually drawing the line representing x = π, you can use ContourPlot to visualize the relation: The Epilog option can include any combination of Mathematica‘s graphics directives, such as colors and dashing: Here’s a version with multiple dashed grid lines:Īnother way to get the vertical line x = π is to explicitly tell Plot to draw the line after it finishes plotting. You can also use GridLinesStyle to specify colors and styles. The setting GridLines → draws grid lines at the specified lists of points on the x– and y-axes. Any arrangement of horizontal and vertical lines can be produced using the GridLines option: The particular relation x = π is a single vertical line. For PSfrag-based images changing a label only requires editing the corresponding psfrag macro in the TEX file associated to the image, whereas rescal- ing of. There are a few different ways to combine a regular plot of a function with a visualization of a relation. You can plot two or more functions together by giving a list as the first argument of a function like Plot:īut a relation like x = π is not a function, since it doesn’t define a single function value for each x. How can I plot a function like sin(x) together with a relation like x = π?
