patmartin / dexjs Goto Github PK

Hello, I'm very interested in utilizing this in my current project. Problem is: I need to draw 1000*2000 cells per heatmap. With the potential of adding 1000 cells per second.

Is it possible to just shift points on the left while adding 1000 new cells on the right without completely redrawing the map?

I've tried your Treemap demo in several browsers : https://bl.ocks.org/PatMartin/112191b94399a5e4172c7d2621b31df5
It works perfectly fine. Unfortunately the names of the states aren't correctly displayed in Internet Explorer (11).

Would like to see support for loading external CSV files, rather than a column-formatted json

Just starting with dex.js, I tried the example https://bl.ocks.org/PatMartin/0fccfddf5277e01cd5024d963f0caa70, which worked fine.

I then replaced the presidential data with

["10.1.1.1", "10.2.2.2", "22"],
["10.1.1.1", "10.2.2.2", "50"],
["10.1.1.2", "10.2.2.2", "22"],
["10.1.1.3", "10.2.2.2", "22"]

The chart crashed, DevTools show

Uncaught TypeError: Cannot read property 'id' of undefined

I did some try-and-fail tests and it looks like the data must be alphanumeric? For instance bare numbers ("45") are rejected when the data are only numbers, while numbers with an underscore are fine ("45_")

Your demo : https://bl.ocks.org/PatMartin/2b3d11ad2eef3c57f9b9561cda7e64bd seams to contain some bug. I've tried it in several browsers : the screen starts flashing, as if the program is in some eternal loop.
