1 Days with Price Changes

This workflow describes a challenge to solve during the hackathon: Determine automatically if a value is different from the previous row.

DescriptionYou are using KNIME to monitor the daily price of a product online. After using the Line Plot node tovisualize the daily prices you have already gathered, you notice that they are often constant for a certainnumber of days before changing again. You want to create a new column in the price data you have athand, named "Change", such that its value is 1 if a daily price changed with respect to the previous day, or0 if it remained unchanged. For the first daily price in the data, the "Change" value should be 1. daily_prices.csv CSV Reader Line Plot (Labs) DescriptionYou are using KNIME to monitor the daily price of a product online.
