A bubble chart is for users 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.
To generate a Bubble Chart, you first need to be in the 'Reports' section where you will then be able to click 'Add Report' in at least one of the highlighted locations below.
By clicking the button it should bring you onto a report selection page where you are shown various reports and some information about them. To choose a 'Bubble Chart' find the card containing the 'Bubble' chart then click on 'Create'. Alternatively, you can find it by searching and selecting 'Bubble' on 'Filter Types'.
Consequently, this presents you with the Report configuration options below:
Title: The title is the reference to the Report that will appear in the App for the users. It will appear in the left pane menu for the and also in the breadcrumb (header bar) at the top of the page which tells the user where they are on the site.
Sub Title: The subtitle is a banner that appears at the top of the screen beneath the title that allows you to give a short description the report, this can be useful for keys and user audience.
Identifier: This should reflect the label. The identifier is a system ID for referencing a Report. This ID must be unique per Report and must contain only letters and numbers starting with a letter. It must also be a minimum of three characters.
- Chart - Has to be selected for Bubble
Group: The Report Group is used if you need to group reports together. A Report Group will appear on the left pane, and once clicked, show the Reports in it below. They are collapsed when the App is first launched, and expandable as required.
Note: Report Groups will always display below non-grouped Reports.
Is Default: The default Report is the Report that the user will be directed to the first time that they open the App. If no default has been set then the user will be navigated to the Report with the lowest display order.
Note: Once a user navigates to a different Report, this preference will override the default option the next time they view the App if they haven't logged out in-between.
Is Hidden: This will hide the report from all users. It is commonly used whilst a Report is being reconfigured or if a Report needs to be removed temporarily to be reinstated at a later date.
Chart Type: Choose from over 15 Chart Types - Here you will need to select 'spline'.
In-App Data Source Field: Some chart types can be created from Grid Field data to produce In-App Charts To select the Grid Field that the data will come from you can choose this as the In-App Data Source Field.
Background Image URI: This option allows you to have an image behind the Chart by entering the image's Uniform Resource Identifier (URI). This generally is a character sequence identifying a resource, usually on the internet. In this context it identifies your chosen image which can be useful to indicate zones within the chart for instance, or simply for more tailored branding.
Base Filter: If the report is to always show a subset of Records, then the Base Filter can be used to apply a permanent Filter to the report. This Filter is always applied, and then user-defined filters and searches are compounded on top when the report is being used - For more about configuring base filters click here
Target Click-Through Report - With 'Target Click-Through', you can select a List Report for the user to drill down into to display more information about the Records that meet the criteria. It will apply the appropriate filters to that List Report to only show the relevant records. This can make an effective navigation tool for the App.
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
X Expression: an expression yielding a value to be used as the X Axis
Y Expression: an expression yielding a value to be used as the Y Axis
Z Expression: an expression yielding a value to be used as the Z Axis (Size of the bubble)
Example Summary Expressions:
"3" : a hard value
Similar to how app visibility works this can be set to hide your reports from certain users or teams, this can be great for hiding reports from certain teams or guests, for example, if you have employee-based performance reports that you only want management to see so you set it so just that team can see it.
Make sure to click the 'Save' button when making any changes in order for them to be added to the next app version. Once you have made all the changes you need to an application you are then ready to publish it to workspace.
