Captures won't display with long capture periods

[ryan-summers]

For capture periods longer than ~150ms, the capture doesn't appear at all. Investigation of the console log indicates that Javascript hits a memory exception and drops the serialized data.

This should be resolved either by limiting the size of the data sent to the front end (limiting number of points) or by drawing the display in chunks of a specific size.

No time domain display/analysis is currently present.
