Serious Lag expanding Niagara river (and others) due to graph #108

Closed ecc521 closed 2 years ago

ecc521 commented 4 years ago

The Niagara river (https://rivers.run/#Niagara%20Fort%20Erie) reports data extremely frequently, so graph contains several hundred points. This results in a multi second lag opening the river view once full data has been loaded (the initial load is only a few data points, so works at normal speed. Once full data is loaded, full data is drawn on future openings, resulting in heavy lag)

This is now significantly more important with the NWS gauges - offscreen canvas should probably be used

d1d5a1ca massively mitigates this issue, making it far less catastrophic. Backgrounding should be done, but it is now an enhancement, not a critical issue.

This issue is more serious with additional USGS data as of 0ccaf5e7, and impedes the potential addition of more data (like 7 days)
