Charts in cloud with IBM’s Bluemix
This tutorial shows how to build a simple chart on the cloud with a simple node that sends values to the cloud.
Here how the result looks like:
For this tutorial, we use the IoT Bluemix cloud from IBM and a node also provided by IBM to send datas.
IBM offers a GREAT idea named “QuickStart” where you can get a result without all the pain of registering the service. First give a seamless result to the customer, then if he wants more you can ask him to invest some time (or money). Great lesson a lot of cloud service providers should ear.
Install the nodes
Click the right menu in the Node-RED web page. Choose Manage Palette then Install.
Type node-red-contrib-ibm-watson-iot in the edit box and click the OK button.
Wait for the install
The installation may take up to 5 minutes (a progress bar shows the progress), depending on what is already installed on your device.
Then reboot and then refresh the web browser page.
Browse the palette and look at the newly added nodes.
A first simple flow
Drag’n drop it on the workspace, and double click it to set parameters:
You can click the button below to get the cloud bluemix chart:
all these technical datas should normally not appear in a quickstart node that provide a seamless user experience.
Send data and build a chart
Now you can send any numeric value. Let’s build the simpliest flow: add an “inject” node and set it to send the current date as a number every one second:
And look the beautiful result:
Beyond this Quickstart mode, IBM offers a full featured cloud for IoT.
