 Re: [Matplotlib-users] How do you Plot data generated by a python script? From: surfcast23 - 2011-08-26 01:35:07 ```Hi, I apologize if my explanation was less than clear. What I have is data in a column that runs from row 1 to row 1268. In each each row there is a number. For example 1 3 5 6 7 8 9 so I want the y axis to run from 1 to 7 ( the number of rows) and the x axis to be the average of the values in this case 5.57. I am having problems with setting up the y-axis as well as the dimension problem you addressed. Is there a way I could have every value on the x axis the same? Say for the above example have the x and y axis be 7 6 5 4 3 2 1 5.75 5.57 5.57 5.75 5.57 5.57 5.75 Which would be the number of rows vs the average value of the data in the rows and then plot that?
