The follower chart on the Overview tab plots the historical follower count of the profile, so you can see when the creator gained or lost followers. Above the chart, the monthly growth shows the absolute and percentage change over the last 30 days. Depending on the platform, you can switch the chart between metrics: on TikTok between followers and impressions (TikTok additionally tracks the cumulative number of deleted posts), on YouTube between followers and the median views of videos and shorts — and you can limit the displayed time period.
Look for steady, organic growth. Sudden spikes and drops can indicate purchased followers, while a flat curve suggests inactivity or low reach — but keep the context in mind: a viral post, a big collaboration or media coverage can also cause a natural jump.
Chart not available? If you see the message "Sorry, we don't have enough data to show a graph", influData has not been observing this profile long enough to have several follower data points. The history builds up with the regular profile updates, so the chart appears once enough data points have been collected.
