Changing The Domain Of A Scale Without Shifting The Entire Plot

I am working on a realtime simulation. I generate an hour of data, but I only want to present a portion of that, and scroll the plot when I get close to the right edge. I define tw

Solution 1:

I figured out what I was missing. Adding

    "padding": {"left":100, "right": 100, "top": 50, "bottom":100},

fixed the problem.

Solution 2:

Would you mind sharing the portion of your code that performs filtering? The Vega 3 code I wrote like this, works for one spec with symbols marks but not for another spec with line marks.

data: [
    {
        name: 'table',
        transform: [
            { type: 'filter', expr: 'datum.l >= timeStart && datum.l <= timeEnd' }
        ],      
        values: [blah blah]
    }
]

In https://github.com/vega/vega/issues/113, kjavia mentions a "tearing" effect which I see in my spec with line marks.
