Hi,
I am working in asp.net 4.5 and i tried to plot the column chart with
Google API. But seems i am missing the Vaxis line and i am helpless how to
plot the vaxis line. usually there will be L shape on this. but i ma
missing the V axis. please show me some sample how to plot the v-axis line.
My Sample Code posted here,
Enter code here...<script type="text/javascript">
//debugger;
google.load("visualization", "1", { packages: ["corechart"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
var options = {
title: 'Data'
};
$.ajax({
type: "POST",
url: "Sample.aspx/Report",
data: '{}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (r) {
//var data = google.visualization.arrayToDataTable(r.d);
var Reportdata = new google.visualization.DataTable();
Reportdata.addColumn('string', 'Month');
Reportdata.addColumn('number', 'Mark');
Reportdata.addColumn({ type: 'string', role: 'style' });
var chartData = [];
$.each(r.d, function (i, item) {
var mark = parseInt(item.Mark);
var markcolor;
if (mark <= 39)
{
markcolor = "color:red";
}
if (mark > 39 && mark <=69) {
markcolor = "color:orange";
}
if (mark >= 70) {
markcolor = "color:green";
}
chartData.push([item.Month, mark, markcolor])
});
Reportdata.addRows(chartData);
var view = new google.visualization.DataView(Reportdata);
//view.setColumns([0, 1,
// {
// calc: "stringify",
// sourceColumn: 1,
// type: "string",
// role: "annotation"
// },
// 2]);
var options = {
title: "Six Month Graph",
width: 600,
height: 400,
slantedText: true,
bar: { groupWidth: "95%" },
legend: { position: "none" },
hAxis: {
//direction: -1,
slantedText: true,
slantedTextAngle: 90 // here you can even use 180
},
};
var chart = new
google.visualization.ColumnChart($("#chart")[0]);
chart.draw(view, options);
},
failure: function (r) {
alert(r.d);
},
error: function (r) {
alert(r.d);
}
});
}
</script>
