They use the views plugin to do this, without (paying) this, you cannot do it.
Once you get the plugin, create a view with all your projects, use the view toolbar as the main control panel (in the control panel) and add the following widgets: "SQALE Overview", "Problems and Technical Debt", "Timeline", "measure the filter as a donut chart" and "measure the filter as a treemap".
What is this, welcome.
