Clustering using kmeans algorithm

Hi

I am trying to utilize the simple k-means algorithm to create a 
clustering model

The data set is a series of records each containing 5 consecutive 
numerical price values e.g. 1.30965, 1.30979, 1,31008, 1,31020, 1,32045

I am setting k = 25 for the number of clusters

When I run the clustering algorithm the result shows the 25 clusters but 
they are based solely on the average price level of the 5 data input points

What I am seeking is clustering that reflects the graph of the various 5 
input data prices

e.g. if the five price input data values increase steadily, I wish one 
of the clusters to reflect that sort of increasing graph

On the other hand, for example, the graph of the 5 input data prices may 
look live a 'v' - decreasing, then increasing

I am seeking another cluster of data inputs that reflects that type of graph

How do I do this in weka please ?
