MATLAB ® automatically selects the contour lines to display. 目前搞到的shape文件有：中国科学院资源环境数据、从CSDN上下载的、奇哥给的。 1. c = colorbar ( ___) returns the ColorBar object. contourf (X,Y,Z), contourf (X,Y,Z,n), and contourf (X,Y,Z,v) produce contour plots of Z using X and Y to determine the x - and y -axis limits. Accepted Answer. However, U is row vector 1x12792 double and the values of x and y are distributed non-uniformly, because they are coordinates of the triangle mesh nodes. % See c. Works brilliantly, thank you. End-users most likely won't need to directly use this module's API. x = 100*rand (100,100); contourf (x,'Linestyle','none'); set (gca,'view', ( [5,30])); axis ( [0 100 0 100 0 1]); c = colorbar; %%. Below is an example of changing the font size, color, and type for the labels on a contour plot: Theme. I get data from Comsol via LiveLink to Matlab. fig,ax = plt. set these inversly scaled colorbar ticks: set(a3,'YTickLabel',ticks) and you finally get a seemingly linearized plot (but you could just backup your non-linear data from before), with a with non-linear colormap and colorbar ticks. I would like to plot 3D data as a contour plot but. Here is an example where a part of a contour plot is shaded using another contour plot. Yes, it is possible to rotate a contour plot in MATLAB by custom angles using the rotate function. Plotting in Julia like Matlab plots. Default is false. Colorbars allow you to see the relationship between your data and the colors displayed in your chart. MATLAB: How to designate color in contour plot with specific values Here's a demo. You can either tell MATLAB how many levels you want. Then when you call caxis, you get rid of any color distinction above 2 or below -2 (>2 all have same color, <-2 all have same color). To do so, I use the following code: h = figure ('windowstyle', 'docked'); contourf (mesh_x, mesh_y, Z, 20) colormap (jet (20)) colorbar caxis ( [-10 10]) Below is a picture of the result. colorbar (location) displays the colorbar in a specific location such as 'northoutside'. set these inversly scaled colorbar ticks: set(a3,'YTickLabel',ticks) and you finally get a seemingly linearized plot (but you could just backup your non-linear data from before), with a with non-linear colormap and colorbar ticks. Your lowest contour is set to the min value but that is a single point in the 256x256 array. Otherwise, the colormap contains 10 colors. To elaborate: colorbar, by default, will display a color bar of the current color map, which you can set with the command colormap. Colorbars allow you to see the relationship between your data and the colors displayed in your chart. You're probably using a colormap with 256 breakpoints when you want 4. pcolormesh (X, Y, v, cmap=cm, clim= (-4, 4)) If the colorbar range has to be updated after the pcolormesh call, then the easiest way is plt. Same color means the same height. ceil 朝正无穷大方向取整. Oct 29, 2009.

I have made a contourf interpolating results with meshgrid and it plots a graph which does not correspond to the values that I put as input with the colors of the colorbar (There are points where it should be yellow or red and it is blue, or other points which have markedly different values and are the same color). The 16 contour lines have been drawn for that. contourfcmap(x,y,z,clev,cmap, 'evencb', evencb) indicates whether to space the colors on the colorbar evenly (evencb = true) or to size them according to the clev values (evencb = false). How to display all the colors in the color bar into the contourf plot? Ask Question Asked 7 years ago Modified 6 years, 11 months ago Viewed 213 times 0 I have this beautiful code which displays two contour plots. ButtonDownFcn = @myMouseClickCallback; And in the callback function: function myMouseClickCallback ( hContour. contourf(x,y,Data,v) the colormap shown scales itself with. Colorbars allow you to see the relationship between your data and the colors displayed in your chart. contourf (Z) creates a filled contour plot containing the isolines of matrix Z, where Z contains height values on the x - y plane. Steps to use colorbar command – Step 1: accept any plot or graph Step 2: write color bar command and assign it to one variable Step 3: apply properties of colorbar Step 4:. Note that the colormap uses the same number of contour intervals. Not all types of charts support modifying the colorbar location.

You can use CAXIS to change this. colorbar ( ___,Name,Value) modifies the colorbar appearance using one or more name-value pair arguments. Please take a look at the following visualization. ax = gca; axpos = ax. linspace(-M,M,61)而不是使用vmin和vmax使用levels=62设置时，这种行为是我所期望的。 下面的示例显示了我在 scatter 示例中所希望的默认. 【程序设计】散点密度图 我仔细研究了一下，这个图还得根据自己学科以及想做的东西来进行计算，我这个学科更多统计的频率和数量，他们统计的是密度！ 本次程序我自己编写，没使用matlab自带函数kdensity,因为我知. 1 Answer. That will depend on which version of Matlab you're running, and whether you have the Mapping Toolbox (those two factors determine whether contourfcmap output is contourgroup objects or patch and line objects. fig,ax = plt. PNG matrix. Type: import matplotlib. Change point meta max to 64 (maybe, don't really know what Matlab used, but it looked similar) point meta max defines the maximum value for the colorbar, which you can see from your image is 1 in the pgfplots version, and something else in. Then when you call caxis, you get rid of any color distinction above 2 or below -2 (>2 all have same color, <-2 all have same color). To reduce the Color edges, you can increase the number of value-steps. 说明 示例 colorbar 在当前坐标区或图的右侧显示一个垂直颜色栏。 颜色栏显示当前颜色图并指示数据值到颜色图的映射。 示例 colorbar (location) 在特定位置显示颜色栏，例如 'northoutside' 。 并非所有类型的图都支持修改颜色栏位置。 示例 colorbar ( ___,Name,Value) 使用一个或多个名称-值对组参数修改颜色栏外观。 例如， 'Direction','reverse' 将反转色阶。 指定 Name,Value 作为上述任一语法中的最后一个参数对组。 并非所有类型的图都支持修改颜色栏外观。 colorbar (target, ___) 在 target 指定的坐标区或图上添加一个颜色栏。. Produce the contour plot. EDIT: Made the range fit both. colorbar ( ___,Name,Value) modifies the colorbar appearance using one or more name-value pair arguments. 01, and a small variation between 0 and -1. The axis. For example, 'Direction','reverse' reverses the color scale. Therefore I used the code: Theme. To reduce the Color edges, you can increase the number of value-steps. Note that the colormap uses the same number of contour intervals. MATLAB also includes a number of commands to help you work with str. Syntax: matplotlib. Description contourcmap (cmap) sets the colormap of the current figure (and current axes) to a predefined colormap. The 16 contour lines have been drawn for that. In order to see changes throughout the whole scale I want to use a log scale fo caxis. contourf (Z); colorbar colormap ('jet'); caxis ( [0 100]) I can't explain how it's picking the color it picks (it appears to be the color in the middle of the colormap), but the. As a possible workaround, you may manually define a contour of the area which you want to make transparent. cd 设置当前工作目录. Learn more about colorbar, xtick, changing the location and labeling of ticks on a colorbar How do I set the ticks in a color bar to be at specific values?
