Labels to dataserie operator operator

The Labels to dataserie operator operator is a WireCloud operator that provides the ability to transform a label series into a number series, so it can be used with other components like the calculate-tendency operator and the column-chart-generator operator.

NOTE: This WireCloud operator is based on labels-to-dataserie-operator of agile-dashboards created by CoNWeT Lab., Universidad Politecnica de Madrid and Future Internet Consulting and Development Solutions S.L..

Build

Be sure to have installed Node.js in your system. For example, you can install it on Ubuntu and Debian running the following commands:

curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install nodejs
sudo apt-get install npm

If you want the last version of the operator, you should change to the develop branch:

git checkout develop

Install other npm dependencies by running: (need root because some libraries use applications, check package.json before to be sure)

sudo npm install

For build the operator you need download grunt:

sudo npm install -g grunt-cli

And now, you can use grunt:

grunt

If everything goes well, you will find a wgt file in the dist folder.

Wiring

Input Endpoints

• Label list: The list of labels to be transformed

Output Endpoints

• Data serie: The data serie obtained.
• Reduced label serie: The labels for each of the values of the Data serie

Usage

Plug a label list to transform it into a number list. The output Data serie will be a list with the count of appearances for each of the input labels. The Reduced label serie its the labels associated to each of the counts, in the same order as in the Data serie. Hence, there won't be any repeated labels.
