question about jsnippet‏


I´m using knime for processing stock market data.
Inside jsnippet node I want to read the actual row value and previous row values, but I don´t know how can I do that. For example, inside a jsnippet I want to work with the actual close price and the close price of the last 30 days.  I´ve didn´t see a getCellValue(rowIndex, columnIndex) or something like this. 
Thank you

You only have access to indiviual column values. I f you want to have access to values of previous rows, you need to use the Global Variable Declaration as described in this thread.
