I have 4 entities and I show them for 4 days. But first and last days I cant s
I recently had to build a chart like this. Please consider my code for your solution:
Put this in your Controller:
<EmployeeAuthorize()>
Function WeightAreaChartData() As JsonResult
Dim myData = db.Tbl_Weights.Where(Function(x) x.Weight_Employee_ID).OrderBy(Function(x) x.Weight_Create_Date)
Dim data = New List(Of Object)
data.Add(New Object() {"Date", "Your Weight"})
For Each i As Tbl_Weight In myData
data.Add(New Object() {DateTime.Parse(i.Weight_Create_Date).Day, i.Weight_Amount})
Next
Return Json(data, JsonRequestBehavior.AllowGet)
End Function
Put this in your view; changing the $.post() URL accordingly:
<script type="text/javascript">
google.load("visualization", "1", { packages: ["corechart"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
$.post('/Weight/WeightAreaChartData', {},
function (data) {
var tdata = new google.visualization.arrayToDataTable(data);
var options = {
title: 'Weight Lost & Gained This Month',
hAxis: { title: 'Day of Month', titleTextStyle: { color: '#1E4A08'} },
vAxis: { title: 'Lbs.', titleTextStyle: { color: '#1E4A08'} },
chartArea: { left: 50, top: 30, width: "75%" },
colors: ['#FF8100']
};
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
chart.draw(tdata, options);
});
}
</script>
<div id="chart_div" style="width: 580px; height: 200px;"></div>
To fix your specific issue of the bars being cut off, I believe you can use this in your options:
hAxis: {
viewWindowMode: 'pretty'
}
Like this:
var options = {
title: 'Weight Lost & Gained This Month',
hAxis: { title: 'Day of Month', titleTextStyle: { color: '#1E4A08'} },
vAxis: { title: 'Lbs.', titleTextStyle: { color: '#1E4A08' } },
chartArea: { left: 50, top: 30, width: "75%" },
colors: ['#FF8100', 'blue'],
hAxis: {
viewWindowMode: 'pretty'
}
};
