Tomer I want to use MATLAB to plot the height line of a function (represented by a matrix). I'm familiar with contours, but contours draw lines at equidistant heights, whereas I'd like to see lines drawn with constant distances (with height labels). This means
lead Can you tell me how to draw the following figure (smooth transition of colors) in Matlab graphics? The function countouronly allows to create plots with contour lines, and contour lines do not give me enough information. Luis Mendo You can use it with a c
lucky I am trying to draw contour plots in Matlab. However, the syntax seems to be correct, but since the matrix can be quite large, matlab takes a lot of time to plot it. Please suggest what should I do. Below is my code: s = 10000000;
eta_gamma = zeros(s/100

Joan Carl Montero Jimenez With the following code, I get the following contour plot: fig, ax = plt.subplots()
x = np.arange(431)
y = np.arange(225)
Y, X = np.meshgrid(y, x)
values = df["Appearance_percentage"].values
values2d = np.reshape(values, (431, 225))

I don't have enough smooth curves. What do I need? Chief Pavel Mestre You can use functions like griddata and csaps . Together they will lead you to the smoothin

or I also followed the example here to generate filled contour plots using gnuplot. The gnuplot command and output are: reset
f(x,y)=sin(1.3*x)*cos(.9*y)+cos(.8*x)*sin(1.9*y)+cos(y*.2*x)
set xrange [-5:5]
set yrange [-5:5]
