95th percentile line chart does not display correctly on the Response Times (ms) graph

[borget]

Prerequisites

• [X] I am using the latest version of Locust
• [X] I am reporting a bug, not asking a question

Description

The 95th percentile line chart does not correctly display over time,

Every time you do a hard refresh on the Charts screen (http://mylocust.com/?tab=charts) The 95th line starts getting render from the start of the test, and it does not show the historical values.

Example of refreshing the page to see the 95th line behavior

The 95th percentile line shows up correctly going directly to the Locust test report

Command line

-f my_test.py --autostart --modern-ui

@andrewbaldwin44 Can you take a look?

@borget Is it working now for you? (use pip install --pre -U locust to get the most recent build)

Hi @cyberw ! Just wanted to share that the solution is still going strong after a month and I just upgraded to locust== 2.22.0. Huge thanks to everyone for the support
