What does a contour plot tell you?

Contour plots (sometimes called Level Plots) are a way to show a three-dimensional surface on a two-dimensional plane. It graphs two predictor variables X Y on the y-axis and a response variable Z as contours. These contours are sometimes called z-slices or iso-response values.

How do you create contouring labels?

Contour labeling

  1. Ensure the Maplex Label Engine is enabled.
  2. Set up the Contour Placement style.
  3. Create a halo behind the feature.
  4. Create a label expression that only labels every hundredth interval. Use one of the ArcGIS Arcade label expressions below, depending on your data.

How do you analyze contours?


  1. Prepare to contour. A. Search for continuity (time and space) on the weather map B.
  2. Drawing the map. A. Use a pencil !!
  3. Review your map. A. Do a gross check of isopleths for accuracy B.
  4. Your map is now ready for interpretation!

How do you plot a color map on Origin?

SelectPlot > Contour: Contour – Color Fill to create a graph. Double click on the contour plot to open the Plot Details dialog. On the Colormap/Contours tab, click on the Line heading to open the Contour Lines dialog. Deselect Shown on Major Levels Only and select Hide All to hide all the contour lines.

How do you change the contour color in python?

The default color scheme of Matplotlib contour and filled contour plots can be modified. A general way to modify the color scheme is to call Matplotlib’s plt. get_cmap() function that outputs a color map object. There are many different colormaps available to apply to contour plots.

Why use a contour plot?

A contour plot provides a two-dimensional view in which all points that have the same response are connected to produce contour lines of constant responses. Contour plots are useful for investigating desirable response values and operating conditions.

How do you read a contour line graph?

How To Read Contour Lines

  1. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line.
  2. Intermediate lines are the thinner, more common, lines between the index lines.
  3. Supplementary lines appear as dotted lines, indicating flatter terrain.

How do I label contour lines in ArcGIS?


  1. Right-click the layer name in the ArcMap table of contents and select Properties.
  2. Click the Labels tab to set the contour line properties.
  3. Click the Symbol button to view the Symbol Selector window and adjust the labels.
  4. Click OK to close the Editor window, and OK again to close the Symbol Selector window.

How are contour maps useful?

Contour maps help us to understand the characteristics of the landforms. These maps are of immense use to mountaineers, trekkers, soldiers, defense officers, etc. These maps prove to be of great use in the planning for a region too.

How are contour lines drawn on maps?

Contour lines are the main characteristics of a map. Contour lines are lines drawn on a map with equal elevation points, so elevation would be constant if you followed the contour line physically. The elevation and terrain shape of the contour lines shows.

How do you draw a contour plot in IDL?

CONTOUR The CONTOUR function draws a two-dimensional contour plot for a 2D array of data. Instead of data, you can also input an equation of X and Y using either the input argument or the EQUATION property. In this case IDL will automatically generate the independent X and Y values and use your equation to compute the dependent Z data.

What is the default color range for a line contour?

The default colortable for line contours is 55, and for filled contours the default is 49 (reversed). Note: When you retrieve the COLOR property, the returned value will always be a three-element RGB vector, regardless of how the color was initially specified.

How do I use contour levels in C_colors?

If there are more contour levels than elements in C_COLORS, the elements of the color vector are cyclically repeated. If C_COLORS contains three elements, and there are seven contour levels to be drawn, the colors c0, c1, c2, c0, c1, c2, c0 will be used for the seven levels. To call CONTOUR and set the colors to [100,150,200], use the command:

Does contour use follow in IDL?

In IDL version 5, CONTOUR always uses a line-following method. The FOLLOW keyword remains available for compatibility with existing code, but is no longer necessary. As in previous versions of IDL, setting FOLLOW will cause CONTOUR to draw contour labels.
