Hello all and sorry for my bad english, i am a beginner with python and i try to save a lot of data in several folders in a 4D matrix and then to plot two columns of this 4D matrix.
Bellow, i have the code to fill my 4D matrix, it works very well : [CODE]matrix4D=[] for i in Numbers: readInFolder=folderPrefixe+i+"/" matrix3D=[] for j in listeOfdata: nameOfFile=filePrefixe+i+"-"+j+extensionTXT nameOfFile=readInFolder+nameOfFile matrix2D=np.loadtxt(nameOfFile,delimiter=",",skiprows=1) matrix3D.append(matrix2D) matrix4D.append(matrix3D) array4D = np.asarray(matrix4D)[/CODE] But now, i want to plot the third column as function of the third too (just for trying) and i use this stupid manner that works well : [CODE]plt.figure(1) temp=plt.plot(array4D[0][0][0][0],array4D[0][0][0][0],'bo') temp=plt.plot(array4D[0][0][1][0],array4D[0][0][1][0],'bo') temp=plt.plot(array4D[0][0][2][0],array4D[0][0][2][0],'bo') temp=plt.plot(array4D[0][0][3][0],array4D[0][0][3][0],'bo') plt.show()[/CODE] Now, i want to use a more smart manner and i use ":" like this [CODE]plt.figure(1) temp=plt.plot(array4D[0][0][0:3][0],array4D[0][0][0:3][0],'bo') plt.show()[/CODE] The result should be the same but i don't got the same results!!! In attachement you have the two corresponding plots, can you explain to me with i don't have the same plots ?? thanks for all
