Static Pie Chart: Understand Google Visualization

Create a pie chart

How to configure it:

• Create a new RMP user interface

• Include this as a .js in the headers of your webform (this is a google library with pie chart package)

  https://www.gstatic.com/charts/loader.js

• Add an html widget with the following code :

Code

<div id="chart_div"><div>

• Add a calculated gadget in your RMP webform with this script :

Code

      // Load the Visualization API and the corechart package.
      google.charts.load('current', {'packages':['corechart']});

      // Set a callback to run when the Google Visualization API is loaded.
      google.charts.setOnLoadCallback(drawChart);

      // Callback that creates and populates a data table,
      // instantiates the pie chart, passes in the data and
      // draws it.
      function drawChart() {

        // Create the data table.
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Topping');
        data.addColumn('number', 'Slices');
        data.addRows([
          ['Mushrooms', 3],
          ['Onions', 1],
          ['Olives', 1],
          ['Zucchini', 1],
          ['Pepperoni', 2]
        ]);

        // Set chart options
        var options = {'title':'How Much Pizza I Ate Last Night',
                       'width':400,
                       'height':300};

        // Instantiate and draw our chart, passing in some options.
        var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }

• Save your webform, switch to test mode and preview!

You can now adapt this feature to your own data source : you just have to compute array_column and array_data (thanks to a RunMyProcess process listener for example) and call this js function

This is the best way of designing your dashboards within RunMyProcess webforms.

This feature doesn't requires working in a google environment as this is not a google gadget
