  • 0

I have an activity which inserts data into the db. What I am looking for is to get the data from the database. It is a SQLite database. I need the data in the form of a multidimensional array using Javascript in order to plot a graph using the retrieved values in jqPlot.

Please, I have searched a long time with no result.

Please help, I know to plot using hard coded values but not with the values coming from database.

Please help.

    done at last 🙂 , works !!! 

    <script type="text/javascript">
db.transaction(function(transaction) {
transaction.executeSql('SELECT * FROM Weight  ;', [],
function(transaction, result) {
alert( result.rows.length);
var line1=[];
if (result != null && result.rows != null) {
for (var i = 0; i < result.rows.length; i++) {
var row = result.rows.item(i);

    line1[i] = [row.date, row.Weight];
    } //for loop close 

     $(document).ready(function(){


var plot1 = $.jqplot('chart1', [line1], {
title: 'Date  Vs Calories',series:[{renderer:$.jqplot.BarRenderer}],axes: {xaxis: {label:'Date',renderer: $.jqplot.CategoryAxisRenderer,tickRenderer: $.jqplot.CanvasAxisTickRenderer ,tickOptions: {angle: -40}},yaxis:{label:'Calories / sec' ,labelRenderer:$.jqplot.CanvasAxisLabelRenderer, labelOptions: {fontFamily: 'Georgia, Serif', fontSize: '12pt' } } }});});

} //if loop close
})// transaction.executesql
}); //function transcation 
</script>
