i have load profile data where x axis is load profile such that for multiple same values of x (constant load) i have different values for y.
till now in excel i used to line plot y and right click graph->selec data->change hoizontal axis data by providing it range o x axis data and that used to give me the graph

Sample Chart

the problem i have is when i try to give
plot(x,y), matplotlib plots y for unique vals of x ie it neglects out all the remaining value of for same value of x.
and when i plot with plot(y) i get sequence numbers on x axis
i tried xticks([0,5,10,15]) for checking out but couldn’t get the required result.
my question is
is it possible to plot a graph in a similar fashion as of excel
the other alternative i could think of was plotting plot(y and plot (x) with same horizontal axis it atleast gives a pictorial idea but is there any means to do it the excel way??

    From your description, it sounds to me like you want to use the “scatter” plotting command instead of the “plot” plotting command. This will allow the use of redundant x-values. Sample code:

    import numpy as np
import matplotlib.pyplot as plt

# Generate some data that has non-unique x-values
x1 = np.linspace(1,50)
y1 = x1**2
y2 = 2*x1
x3 = np.append(x1,x1)
y3 = np.append(y1,y2)

# Now plot it using the scatter command
# Note that some of the abbreviations that work with plot,
# such as 'ro' for red circles don't work with scatter
plt.scatter(x3,y3,color='red',marker='o')

    scatter plot

    As I mentioned in the comments, some of the handy “plot” shortcuts don’t work with “scatter” so you may want to check the documentation: http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.scatter
