# Best Practices

### Data Visualisation

Overview can support number of dashboards and templates depending on your edition type (**free edition:** 1 template 5 widget, **premium and enterprise editions:**unlimited template and widgets) but for good performance **we recommend to use up to 5 templates with maximum 10 widgets each**.

Again, depending on your internet connection and browser performance, requesting too many data points may cause performance issues. For example, requesting 5 years of data with 1 minutes intervals may cause delays and performance issues.&#x20;

### User Groups and Types

We recommend to divide user types in two, such as operational and analytics.

Operational users will require real time, on demand, data with multiple widget usage.

For their perspective, large visual indicators such as gauge or value widgets are useful and more simplistic dashboard designs are needed.

Analytics users are usually more concern about capability of comparative analytics and data manipulation capabilities in order to understand changes on the data.

Due to these differences we recommend to deploy different user groups and overview design strategies depending on their use cases.

### Real Time Data Tracking

Overview widgets do update itself every time you refresh the page, however, using live data switch will help you to track real time changes easily.

In order to not to effect from bandwidth issues we recommend to use live data only if necessary such as real time monitoring.
