We are about to switch to a new forum software. Until then we have removed the registration on this forum.
Hi forum, I am trying to integrate a processing sketch using processing js on the web. I am using the following Table class, extracted from Ben Fry's book Visualizing data.
However, I get the following error: No row named '-1' was found What should be modified in this code??
Someone created the js version of this code but I can no longer find it; it used to be here http://osmeusapontamentos.com/processing/dataVisualizationExamplesUsingProcessingJS.htm . He does specify the main differences he applied but I don't know any javascript...
Thank you!
