Usages of standard dashboard nodes¶

This section describes the dashboard nodes available in Visual Flow Creator.

You can edit the node properties as per requirements. You can set the state of dashboard widgets by sending messages to the corresponding nodes. You can read/ react to values set by users of the dashboard by appending nodes to the outputs of the dashboard nodes.

Note

Industrial IoT is not responsible for the complex dashboard nodes adopted from third party like Vega, Heat map, etc. For more information about the third party dashboard nodes, refer to their official websites.

Button¶

The node will generate a message with payload and topic defined in node settings. By default, the button sends a string with message id as payload. Clicking the button results in generating the message loaded in the payload.

Output in the dashboard window:

Here the size, colour and label of the button has been edited to design a useful flow.

You can use the "dropdown" node to define multiple possible data values. Supported data types are string, number and boolean.

Output in the dashboard window:

Dropdown output

You can customize the dropdown menu by editing the node properties. The "options" field in the node properties allows you to add the required options to design the dropdown menu.

Switch¶

The switch node returns any kind of value (string/ number/ boolean/ json) when it changes state.

Output in the dashboard window:

Output dashboard

The first switch shown is in the "off" mode, and the second switch is in the "on" mode.

Slider¶

You can set the value of the horizontal slider by sending a message to the node. You can react to a user's change to a slider by listening to the output message of the slider node. In order to both set the value and react to the new value, you can select "If msg arrives on input, pass through to output" in the node properties. A slider is defined in terms of the following parameters:

A minimum value
A maximum value
A step value

Input messages are converted to a number. The minimum value is used if conversion fails, and this will update the user interface/ dashboard window. If the value changes, it will be passed to the output.

Output in the dashboard window:

Slider output

Numeric¶

Like the slider, you can use the numeric node to define a range of values in steps with a minimum value and a maximum value.

Output in the dashboard window:

Numeric output

Text input¶

Text-input

The node adds a text input to the dashboard window. The text input node supports the following modes:

Regular text
Email address
Password
Number
Telephone input
Colour picker
Time picker
Week picker
Month picker

Output in the dashboard window:

Text input output

Here, the text input label has been changed to "Enter your name here".

Data picker¶

Date picker

The date picker node allows you to pick dates from the widget.

Output in the dashboard window:

Date picker output

Here, the date picker label has been changed to "Departure date".

Colour picker¶

Colour picker

This node uses the color selector of the system and returns the colour in rgb, hex, hex8, hsv or hsl format. Transparency is also supported for all except hex.

Output in the dashboard window:

Colour picker output

The node label has been edited to "Add colour". Click the colour box and a dropdown to choose colour will appear. You can then choose the required colour.

Form¶

The form node helps you to accumulate multiple form elements and then submit them on a single click as an object.

Output in the dashboard window:

Registration form

You can edit the node properties of the "form" and design the form in the "form elements" section according to requirements.

Text¶

The text node is a read-only widget where you can configure the label and value.

Output in the dashboard window:

Text output

You can customize the text box label for a read-only message.

Gauge¶

The gauge node is of four types:

Standard gauge
Donut
Compass
Level

You can define the ranges with different colours for the gauge nodes.

Output in the dashboard window:

Gauge output

The "gauge" dashboard widget can be customized to appear as one of four possible types.

Chart¶

The chart node can be designed in the following formats:

Line
Bar
Pie

Chart nodes are helpful for multiple data readings. Charts are useful for representations and comparisons of numeric and quantitative information.

Output in the dashboard window:

Chart output

Notification¶

The node creates user alerts as popup notifications.

Output in the dashboard window:

Notification output

Let us consider the following example:

Here, the notification is configured to be displayed on the bottom right. You get the following message in the dashboard window:

Dashboard window

UI control¶

The ui control node allows some dynamic control of the dashboard. Sending a msg.payload of the tab number (from 0) or tab_name will switch to that tab. It refreshes the current opened page if the message contains an empty / unset "tab" property.

Output in the dashboard window:

UI control output

Let us consider the following flow with the defined dashboard groups in the sidebar:

The input node is defined with string "+1". This opens the next tab incrementally in the dashboard window.

Graph window

Similarly, if you define the input node with string "-1", the dashboard window will change to the previous tab, in a reverse order.

When you perform some acitvity in the dashboard window, this node connected with debug node will display the message of payload and loggedInUser details in the message payload.

ui-control-message-output

Template¶

The template node allows you to create and define your own widgets. You can design the widgets within the framework using HTML, JavaScript. You can also override builds in CSS styles.

You can create a template and save it in the library for re-use.

Output in the dashboard window:

Let us consider the simple code given below:

simple_code

You get the following message in the dashboard window:

Template output

Image¶

The image node allows you to add an image to the dashboard in the user interface. It supports different types of image formats. The image file can be uploaded using Insights Hub Monitor. The path represents the File API path to image resource.

Procedure to upload the image¶

To upload the image file to image node, follow these steps:
