Then it uses an adaptive algorithm to subdivide at most MaxRecursion times to generate smooth contours. Executing this line, I get the labels at the correct absolute plot coordinates in the new plot. You will need to do this, for example, if you want to have tick marks at multiples of , or if you want to put a nonlinear scale on an axis. The plot is left blank in any regions where f evaluates to None. Email Required, but never shown. ContourPlot has attribute HoldAll , and evaluates the f i and g i only after assigning specific numerical values to x and y.
In some cases, however, you may want to specify the positions and properties of tick marks explicitly. The outline of this answer is: Ubiquitous Ubiquitous 1 5 Generalizations You should be able to apply burnTooltips to virtually any Graphics object, not just ContourPlot s. Custom contour labels in ContourPlot Ask Question. Here I showed how one can get to the finalized labeled plot from the Tooltip stage.
How permanent are these annotations? It turns out that g isn’t the function that specifies the argument for the Tooltipit actually has to be of Head Tooltip.

Here is what the result might look like: In the function burnTooltipsthe Tooltip is used as a kind of vehicle with which a axwslabel “payload” can be injected into an existing plot, turning it into a dynamic object that accumulates information about aceslabel you click to place labels containing the exact same information that the Tooltip displayed.
There is no label or length to specify for grid lines. For example, one could also try this: For that you first have to know what labels belong to which contour. You should be able to apply burnTooltips to virtually any Graphics object, not just ContourPlot s. This adds tick marks with no labels at cntour of. At positions where f does not evaluate to a real number, holes are left so that the background to the contour plot shows through.
Interactively labeling contours
Normally, Tooltip is the easiest way to label contours because that’s the default behavior of ContourPlot when no ContourLabels option is specified. There are some further questions on how the second argument of ContourLabels works in this question – could I interest you in taking a look? Now I pressed the copy keyboard shortcut and go back to the colored plot coloredPlot I just produced. To do that, right-click the mouse over the completed picture. You will need to do this, for example, if you want to have tick marks at multiples ofor if you want to put a nonlinear scale on an axis.
After entering the labels like this, you can also double-click each pot and edit it further, e. This will display the graphic in the argument again, but now whenever you click on an object displaying a Tooltip axezlabel, the displayed value appears as a static label in the graphic. This should hopefully work with a simple FindRoot in most cases. ContourPlot returns Graphics [ GraphicsComplex [ data ] ].
Next, type the following: Sign up using Email and Password. When you’re done adding the labels at locations where they look good to you, you may want to prevent this dynamic display from receiving any further clicks.
ContourPlot command in MATHEMATICA
The arguments supplied to functions in MeshFunctions and RegionFunction are xyf. Please complete this field. What I usually do is label the contours by hand with the help of the drawing tools.
I had thought that this could be achieved with the option. In your example, the label you want is the parameter t, so to get myself oriented I first defined a ContourLabels function that can display that number:.
Here I showed xxeslabel one can get to the finalized labeled plot from the Tooltip stage. With some settings for PerformanceGoalother specific option settings may be overridden. Next, press t and click where you want to add the first manually placed contour label.
Contohr, you can copy the contour labels from the previous plot as follows:. ContourPlot treats the variables x and y as local, effectively using Block. Ubiquitous Ubiquitous 1 5 ColorFunction is supplied with a single argument, given by default by the average of the scaled values of f for each pair of successive contour levels. If you continue to experience a problem or if you have any questions, please contact us.
Type the number for the contour, and click outside the text to accept the label. The ploh from this is that the manual labor involved in qxeslabel the labels as I showed above is not completely wasted when you re-draw the contour plot, because copying your work preserves the coordinates of the insets.
