Retina is a marketing term coined by Apple that refers to devices and monitors that have a resolution and pixel density so high — roughly 300 or more pixels per inch – that a person is unable to discern the individual pixels at a normal viewing distance 🤓.
In order to generate beautiful charts for these Retina displays, Image-Charts supports a retina mode that can be activated through the
icretina=1 parameter. If the chart URL contains icretina=1 parameter, the generated chart output will have its width and height size doubled.
We recommend the use of
srcset HTML image attribute in order to send the high-resolution image chart version only to retina devices and standard resolution for others, thus reducing bandwidth usage.
Retina support is only enabled in Enterprise+ subscriptions.
