There was a problem hiding this comment.
I guess this resetting of cache might be inconvenient for some future use cases. How about resetting only some groups of caches by the key?
$$.resetCache('MaxTickWidth') // => reset cache which has the key /^\$MaxTickWidth/There was a problem hiding this comment.
I though about this when I tried to use this method for legendItemTextBox too where reseting this cache here would be unnecessary.
I think there will be some kind of tradeoff between ease of use (aka: Forget to reset a cache here & there) & performance.
I think there are 2 families of cached values:
- The ones that are impacted by an update of data (added, removed targets, etc.)
- The ones that are impacted by an update of sizing (resize, update of CSS....)
This PR:
withoutRecomputeand always return cached version if existsaddToCacheandgetFromCacheinstead of custom propertyresetCachewhenredrawis called.This way we have more cache hits and the cache is dropped each time we want to redraw the chart (thinking of resize etc.) which should be, hopefully, sufficient.
