Sampling improves chart rendering performance and it smooths out the chart data somewhat which can make it easier to interpret.
By default, auto-sampling automatically turns on when the focused data set exceeds 2500 data points, and automatically turns
off when a data set is below 2500. Additionally, a toggle effect allows you to alternately turn On or Off the sampling optimizations
for any size data set.
Prerequisites:
Open Chart view (in Workbench or browser) on a component that has a history extension with large amount of data
Perform the following steps:
Click (Sampling) to turn on sampling.
The chart is rendered using the optimized data set.
NOTE: When on, the Sampling icon in the command bar appears selected (has a gray background) .
Click the Sampling button to turn off sampling.
NOTE: In addition to turning off sampling, it no longer turns on and off automatically with the size of the focused data set. It
remains disabled until you reload the page.
