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 userview Dashboard Menu.
Chart Menu Properties
Configure Chart Menu
| Name | Description | Screens (Click to view) |
|---|---|---|
| ID | Menu element unique id. Userview will use this id in the URL for the menu if the Custom ID is empty. |
|
| Custom ID | Item link slug. Optional field. Value defined here must be unique to the rest of the Userview Menus as the first matching name will be called upon. | |
| Label | Menu label. Mandatory field. | |
| Chart Type |

Figure 2: SQL Chart Properties - Datasource |
| Data Binder | When Datasource is set to "Using Data Binder", this option will show up. Advance Form Data Binder has more flexible ways to build chart datasets using join, group, and aggregate function. Please see Datalist Binder for the available binder to use. | |
| SQL Query | When Datasource is set to use any of the "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_hr_expense_claim c
GROUP BY
c.c_claimant

Userview Key Name | When defined, the additional conditions will be appended using the value defined here as the parameter and the userview key value as the value. Example SQL: SELECT category, count(category) FROM table1 Userview Key Name: type Userview Key Value: val Resultant SQL: SELECT category, count(category) FROM table1 WHERE type = 'val' When userview key value is defined, you may define #userviewKey# in your SQL query to have it replaced with the userview key value. Example SQL: SELECT category, count(category) FROM table1 WHERE type = '#userviewKey#' Userview Key Value: val Resultant SQL: SELECT category, count(category) FROM table1 WHERE type = 'val' |

Additional Notes
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(){
$('#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.
