Introduction

Chart menu allows you to select a form binder or define your own SQL query to display the chart data for the most common graph types. You can also include charts in your UI Dashboard Menu.

Chart Menu Properties

Configure Datasource

Figure 2a: SQL Chart Properties - Default Datasource

NameDescription
Datasource

Select the datasource for the chart.

  • Default Datasource
  • Custom Datasource
    • Figure 2b: SQL Chart Properties - Custom Datasource

       
  • Load Data From
    • Figure 2c: SQL Chart Properties - Load Data From

  • Using List
    • Figure 2d: SQL Chart Properties - Using List

SQL Query

When Datasource is set to "Default Datasource" or "Custom Datasource", this option will show up. You use an SQL Query to produce the dataset required for the graph type. The first column in the dataset will be assumed for the X-axis/label.

Example 1:The first column to be returned from the query must be a label (X-axis), followed by value columns for the Y-axis.

Example
SELECT
    c_status AS 'status',
    COUNT(c_status) AS 'count' 
FROM
    app_fd_tix_tickets 
WHERE
    c_status IS NOT NULL 
GROUP BY
    c_status

Example 2:

SQL
SELECT
    c.c_claimant,
    SUM( CAST( replace(c.c_total, '$', '') AS DECIMAL(10, 2)) ) AS 'total',
    AVG( CAST( replace(c.c_total, '$', '') AS DECIMAL(10, 2)) ) AS 'avg' 
FROM
    app_fd_j_expense_claim c 
GROUP BY
    c.c_claimant


Data Store

When Datasource is set to "Load Data From", this option will show up. Advance Form Data Binder has more flexible ways to build chart datasets using join, group, and aggregate functions. Please see Datalist Binder for the available binders to use.

Configure Database

This option is available when the Datasource is set to "Custom Datasource" (Figure 2a).

NameDescription
Database Type

Enter the database type. (example: com.mysql.jdbc.Driver)

Please ensure that the database type entered here is compatible with Joget DX 8. For reference, check this Link.

Target DB URLEnter the Database's URL
UsernameEnter your DB username credential.
PasswordEnter your DB password credential.

Tip

For a reference of what the parameters entered into "Configure Database" should look like, check the default Joget Datasource settings, Expand the admin bar then go to Settings>System Settings>Datasource & Profile Settings.

 

Using List
NameDescription
ListSelect the List that the chart will use to plot data.

Show Export Links

Available when Show tabular data is set to either "Top" or "Bottom". When set to "Yes", this option allows you to export the chart into CSV, Excel, XML or PDF directly from the UI page.

  • Yes
  • No
Show Filters

Available when Show tabular data is set to either "Top" or "Bottom". When set to "Yes", this option allows you to filter the tabular data used to plot the chart directly from the UI page.

  • Yes
  • No

Data Binder & Chart Data Mapping



Remove Padding and Whitespaces from Charts

To hide the padding and utilizing the spacing around the chart, below code can be helpful.

Code to remove padding and spacing

{
      "top": "5px",
      "left": "5px",
      "right": "5px",
      "bottom": "5px"
}

NameDescription
Series Customization
NameDescription
Series NameCustom name for the series of values.
Series CustomizationThis field allows you to insert a script that can modify the graph's visualization. e.g: tooltip : { "trigger" : "item" , "formatter" : {a} {b} : {c} ({d}%) }

Add Row

Add another dataset to be plotted on the Y-axis.
Additional Customization

This field allows you to insert an additional script that can modify the graph's visualization. (e.g: modify legend position)

UI Key Name

When defined, the additional conditions will be appended using the value defined here as the parameter and the UI key value as the value.

Example

SQL: SELECT category, count(category) FROM table1

UI Key Name: type

UI Key Value: val

Resultant SQL:  SELECT category, count(category) FROM table1 WHERE type = 'val'

When UI key value is defined, you may define #userviewKey# in your SQL query to have it replaced with the UI key value.

Example

SQL: SELECT category, count(category) FROM table1 WHERE type = '#userviewKey#'

UI Key Value: val

Resultant SQL:  SELECT category, count(category) FROM table1 WHERE type = 'val'

Additional Notes & Modifications

Display Labels Outside the Pie Chart

The following code can be modified and put in "Custom Header" for displaying the labels outside of the pie chart.

<script>
    $(function(){
        $.jqplot.preParseOptionsHooks.push(function(args){
            args.seriesDefaults.rendererOptions.dataLabelPositionFactor = 1.05;
        });
    });
</script>

 The charts are plotted using jqPlot. Head over to their website here to see the full list of available hooks for customization.


Hide Gridlines from Chart Plot

The following code can be modified and put in "Custom Header" property, to hide gridlines from the chart plot.

<script>
    $(function(){
        $.jqplot.preParseOptionsHooks.push(function(args){
            args.axesDefaults.drawMajorGridlines = false;
        });
    });
</script>

Interactive Chart

The following code can be modified and put in "Custom Footer" for interactive Charts.

<script>
$(document).ready(function(){

	//replace both #jq_plot_chart id with the correct id. can be found by right-clicking the chart and pressing "Inspect"
    $('#jq_plot_chart').bind('jqplotDataClick',
        function (event, seriesIndex, pointIndex, data) {   
            console.log(event);
            console.log(seriesIndex);
            console.log(pointIndex);
            console.log(data);
            
            //for chart which used legend and x-axis, 
            var xaxis = $(".jqplot-xaxis-tick:eq("+pointIndex+")");
            var series = $(".jqplot-table-legend-label:eq("+seriesIndex+")");
            
            console.log("x-axis :" + xaxis.text());
            console.log("series :" + series.text());
        }
    );
 
    //for double click event. Please note the arguments are different.
    $('#jq_plot_chart').bind('jqplotDblClick',
        function (event, coordinate, points, data) {   
            console.log(event);
            console.log(coordinate);
            console.log(points);
            console.log(data);

            if (data) {
                var xaxis = $(".jqplot-xaxis-tick:eq("+data.pointIndex+")");
                var series = $(".jqplot-table-legend-label:eq("+data.seriesIndex+")");

                console.log("values :" + data.data);
                console.log("x-axis :" + xaxis.text());
                console.log("series :" + series.text());
            }
        }
    );
});
</script>

 This code does not work with OHLC and candlestick charts.

The code above only works for charts made with jqPlot


The following code is for interactive charts made with eChart and should also be put in the "Custom Footer". You can find more about interactive ECharts here.

<script>
$(document).ready(function() {
    //ID of one's eChart can be found in html elements of the chart when launching the app
    //which can be found by right-clicking the chart and pressing "Inspect"
	var aChart = echarts.init(document.getElementById('some_id'));

    aChart.on('click', function(params) {
      console.log("Click!");
	  console.log("Data name: " + params.name);
      console.log("Data value: " + params.data);
    });
});
