Description: You are using KNIME to monitor the daily price of a product online. After using the Line Plot node to visualize the daily prices you have already gathered, younotice that they are often constant for a certain number of days before changing again. You want to create a new column in the price data you have at hand, named"Change", such that its value is 1 if a daily price changed with respect to the previous day, or 0 if it remained unchanged. For the first daily price in the data, the "Change"value should be 1. As an example, if the initial daily prices look like:Date Price2015-01-01 102015-01-02 102015-01-03 11You should end up with data in the following format:Date Price Change2015-01-01 10 12015-01-02 10 02015-01-03 11 1----------SOLUTION---------- daily_prices.csvhttps://kni.me/s/vrlYVaryZtBlyTsBsort_by_date_in_ascending_orderprevious_price_for_each_rowdefine_rulesrequired_columnsCSV Reader Sorter Lag Column Rule Engine Column Filter Description: You are using KNIME to monitor the daily price of a product online.
