Geckoboard widgets are constantly refreshing. It's possible, though, that at on occasions the most recent value can't yet be calculated and you'll see a
No data to visualize message.
For example, we will display this message, when there isn't yet any data that the widget can use to build its visualization. This is a temporary state. As soon as the widget successfully gathers the data required to build its visualization, this will be displayed.
If you often see
No data to visualize on a widget, consider adding filters to better control its output, or changing the metric's time-period.
