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.
