Height of each mesh is determined automatically by a weighted average of the data inside the grid. Contour plots are useful for establishing the response values and operating conditions that you want. A contour plot can be created with the plt. They will be color coded, using the same colors as the surface plot. Once a contour plot is created, you can change the color scheme, the line style, trace color, and trace thickness. Contour lines can be a bit difficult to understand, so if you are having trouble, you may find the 3D surface plotter useful to help visualise the actual shape of the 3D surface. I have some data in excel format organized in three columns of x, y, z values. I would like to create a contour plot on polar axes similar to the plots produced by the POLAR function. I have around 50K data points (x,y,z co-ordinates of each point) and the value of a variable at each of these points. A contour plot slices the data into planar groupings and produces outlines/regions that define the boundaries/contours produced by those slices. Go to this component on the Exchange. 2:Unlabelled(andthereforeuseless )contourplot. A 2-D contour can be displayed with a 3-D contour to create a drop-shadow view of the plot (see plottools[transform] for an example). You can create a contour plot with emphasis on selected contour lines by splitting the data and creating two overlapping contour plots. A contour plot provides a 2-dimensional view of the surface where points that have the same response are connected to produce contour lines of constant responses. This can be used even when you are not using the pivot chart, for ordinary contour/surface plots as well. When you hit the calculate button, the demo will calculate the value of the expression over the x and y ranges provided and then plot the result as a surface. 3D Contour Volume Calculation. While 3D plots are eye-catching, a 2D plot can be a more practical way to convey information about the function or data set.
