Hello everyone i working in project that convert data (date and value) to graphic curve . i have problem with x axis the value of date printing in double format , i want this values showing like this format 14:12:35
var gradientBrush = new LinearGradientBrush
{
StartPoint = new System.Windows.Point(0, 0),
EndPoint = new System.Windows.Point(0, 1)
};
gradientBrush.GradientStops.Add(new GradientStop(System.Windows.Media.Color.FromRgb(33, 148, 241), 0.2));
gradientBrush.GradientStops.Add(new GradientStop(Colors.Transparent, 1));
cartesianChart1.Series.Add(new LineSeries
{
Values = GetData(),
Fill = gradientBrush,
StrokeThickness = 0.9,
PointGeometry = null
});
cartesianChart1.Zoom = ZoomingOptions.X;
private ChartValues<DateTimePoint> GetData()
{
var values = new ChartValues<DateTimePoint>();
for (var i = 0; i <lsTemp.Count(); i++)
{
// System.DateTime.Today.AddDays(i)
values.Add(new DateTimePoint(lsDataTime[i], lsTemp[i]));
}
return values;
}
you need to set LabelFormatter property of Axis class. Something like this:
AxisX = new Axis
{
Title = "Date",
Separator = new Separator { IsEnabled = false,Step = 1 },
LabelsRotation = -90,
Foreground = new SolidColorBrush(Colors.Black),
LabelFormatter = value => new System.DateTime((long)value).ToString("t")
};
And look at this link for formats ToString data formats
