A bubble chart is for used to display three dimensions of data for all records, each dimension having a numeric value. The X-axis and Y-axis values dictate where in the chart the bubble will appear and the Z-axis will determine the size of the bubble.
You can also enable a click through on this report which allows the user to drill down into the record that the bubble represents to review that record in more detail.
These are the labels that will appear in the UI for the chosen X-axis, Y-axis, Z-axis, Label, Colour and Hover over Fields.
This is the order that the chosen fields will be displayed.
This is the Field from the Record that will then define the X-axis, Y-axis, Z-axis, Label, Colour or Hover over Fields.
Chart Field Type
X: The X-axis is the horizontal axis. The higher the value a record has for the field defined as the X-axis, the further to the right the record will appear in the chart.
Y: The Y-axis is the vertical axis. The higher the value a record has for the field defined as the Y-axis, the further up the record will appear in the chart.
Z: The Z-axis determines the size of the bubble. The higher the value a records has for the field defined as the Z-axis, the larger the bubble will appear.
Label: The value a record has for the field defined as the Label will be the value that appears on the bubble to define which record the bubble relates to.
Colour: If the app has a RAG or RAGBB field then this field can be selected as the colour field for the chart and each bubble will be the same colour as the value for this field in the record.
Hover Text: This is for additional text that displays when the user hovers their mouse over a bubble on the chart.
Report Summary Expressions
The Summary expressions allow non standard points to be added to the report, which may relate to another App, a fixed point, max values, muin values, average values etc. Multiple additional points can be added
Label: Label of the text point to be shown
Hover Text : When the user hovers the mouse over the point, what value should be shown(non mobile devices)
Colour : Colour of the point to be shown
XExpression : an expression yielding a value to be used as the X Axis
YExpression : an expression yielding a value to be used as the Y Axis
ZExpression : an expression yielding a value to be used as the Z Axis (Size of the bubble)
Example Summary Expressions:
"3" : a hard value
