To go along with the BarChart plugin I made last week I made a scatter plot plugin this week. It can take a series of one dimensional data or a sequence of two dimensional (x and y) data as a space separated list. I haven't come up with a good way to make this work using filters or some other tiddlywiki-based information generating like the bar chart uses and I am a bit disappointed about that.
As with the BarChart plugin there aren't any good annotation options for it yet, I have been trying to work out a reasonable way to add that and not make it much more complex and so far I haven't come up with anything good.
Like with the BarChart plugin I made a tool to help set the parameters for the widget, so if you want to see what the widget can do you can play with that and see all the options.
Let me know what you think.
