Now that you have successfully added your first widget to your dashboard its easy to customise the dashboard further to meet your reporting requirements. From the dashboard itself, you can; rename your dashboard, add and remove widgets and resize and rearrange your widgets on the dashboard "canvas".
Rename your dashboard
As highlighted in the screenshot below, at the top right of a dashboard, you will see the dashboard name. Simply edit the name as you wish, and hit the blue "Save Dashboard" button when done.
Add and remove widgets
Underneath the widget you added to your dashboard, you will see the "add widget" strip that was visible when you first created your dashboard. By following the flow to select an existing widget, or build a new one, you can rapidly add all of the widgets you need.
Resize and rearrange your widgets
As highlighted in the screenshot below, by selecting the bottom-right corner of a widget you can resize it by dragging it left/right to change its width and top/bottom to adjust its height. Clicking on the widget itself will put it in "selection mode" and it will turn red, then you can drag it around the canvas, reordering the widgets show as you prefer.
