Additionally, for the "base" colormaps below, you can set the colormap post-hoc using the corresponding pylab interface function: imshow(X) hot() jet() In interactive mode, this will update the colormap allowing you to see which one works best for your data. However, new features occasionally lead to a di erent behavior. It’s the classic example for a periodic function. So one option is to plot the surface using a colormap as I showed first. my previous questionを考えると、私は、その元のカラーマップparula次rgbデータによって定義されるいくつかのMATLABの等高線図を持っていますカラーバーの最小値が300、最大値が1600であることを知っていれば、3つのサブ図の下のスペースに水平に広がっていますか?. plot returns Line2D objects, which inherently have a discrete color, instead of a "mappable" color which can be displayed on a colorbar. pgfplots is compatible with LATEX, ConTEXt and plain TEX. You could also plot the surface as a single colored (ok, if you insist, coloured) surface with no edges, then using hold on, add only the edges you wish to have plotted. Choose an argument factor, which doesn't divide the period well, and you can see a complicated path around the origin. In the following picture, there is comparison of the correct 'parula' colormap (left bar, colors correspond to the interpolation points) with the result produced by pgfplots (right bar, colors are wrong). Then give the key shading=myshading to \addplot. 2 Curve in forma parametrica 13 2. However, new features occasionally lead to a di erent behavior. Ich denke, dass das Problem ist, dass die Koordinaten schlicht nicht da sind, wenn Du sie brauchst.
