I have a label matrix of segmented image. For example, 1 1 1 2 2 2 3 3 3 4 4 4 1 1 1 2 2 2 3 3 3 4 4 4 1 1 1 2 2 2 3 3 3 4 4 4
I have a function f(x,y) of two variables, of which I need to know the location of the curves at which it crosses zero. ContourPlot does that very efficiently (that is: it uses clever multi-grid metho
I\'m trying to draw the contour of my drawable, I tried to use Blur, as in this page: How to make glow effect around a bitmap?
I\'m trying to reproduce this plot in python with little lu开发者_开发知识库ck: It\'s a simple number density contour currently done in SuperMongo.I\'d like to drop it in favor of Python but the cl
i have problem with creating contour. I have an STL file, the STL file includes many facets,by intersecting facets with cutting plane(Z=dz,x=y=0), we have an array of lines at each incremental Z.
I am tryig to find a way to determine if a contour is closed or not, but I am usign findContours and not cvFindContours so I dont have the flags..
I want to make a contour-plot with a horizontal colorbar. The bar should have labels with scientific notation. Everything goes well in the code below. However, now I want to change the position of the
I have 3 variables (x, y, z) each in a 192x1 vector. The data is all random and sometimes has missing values (NaNs).
Say I开发者_Go百科 have 3 variables such that x=1:9 y=c(1,1,1,2,2,2,3,3,3) z=6:14 How can I rearrange the data so that I can make a contour plot of the data with r?
I have problems with a contour-plot using logarithmic color scaling. I want to specify the levels by hand. Matplotlib, however, draws the color bar in a strange fashion -- the labels 开发者_如何转开发
