Hello. I am trying to update an already existing eyesee canvas from within pharo 2.0. Basically I am getting live data in from a websocket stream, and want to use that live data to build a scatterplot chart.
If I have a lot of data, I can already build the correct eyesee canvas using that data. However, I am having great problems trying to update the already existing canvas dynamically as more data comes in. I spent about 5 hours last night trying various combinations of message sends to the diagramrenderer, the esscatterplot diagram, the escanvas, etc. etc. Eventually I just gave up as I don't understand how the system works. Just to clarify, as long as speed is not a concern I don't mind re-drawing the entire eyesee window every time new data comes in, but the key is I do not want to open a new window every time as I'm sure that would be very user-unfriendly. Thanks, and thanks to the eyesee and moose team. Despite my difficulties with it in this matter, charting with eyesee has been a neat experience. :) -Jacob -- View this message in context: http://forum.world.st/Updating-an-already-open-EyeSee-Canvas-tp4679004.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
