An Area Chart with a logarithmic Y axis compresses a wide value range into a readable scale, so both small and large numbers are visible without the smaller values being flattened against the baseline. This is essential when data spans several orders of magnitude.
This sample plots unique website visitors by month for 2014, where traffic swings from as low as 34 to over 5,700. The logarithmic scale, data-point markers, and always-on labels let you read exact values at a glance, while tooltips provide additional detail on hover via byX interactivity mode.
Follow the step-by-step Area Chart Tutorial to learn how such charts are built. See the Area Chart documentation for all configuration options.
