<Chart>.AddTimeData (Function)

In french: <Graphe>.AjouteDonnéeTemporelle

Adds data in a time chart. A time chart is a chart in which the unit of the X-axis is time (date, time, duration).

This time scale can be used, for example, to represent a change in a measurement (temperature sensor for example) over a day.

Example

nSeries is int = 1
rTemperature is array of 24*60 real

FOR i = 1 TO 24*60 // 24h * 60 mn
d is Duration
d.Minute = i
CHART_TemperatureSensor.AddTimeData(nSeries, d, rTemperature[i])
END

CHART_TemperatureSensor.Draw()

// Sinusoidal drawing
FOR i = 1 TO 360
d is Duration
d.Minute = i
CHART_Sin.AddTimeData(1, d, 2 + Sin(i))
END

CHART_Sin.Draw()

Syntax

<Chart control>.AddTimeData(<Series number> , <Time> , <Value>)

<Chart control>: Control name

Name of the Chart control to be used.

<Series number>: Integer

Number of the series into which a value will be added. If the specified series does not exist, the chart designer creates as many series as necessary in order to get a consistent matrix. All the created series are initialized to 0.

<Time>: Duration or DateTime or Date or Time

Position in time for which the value will be added.

<Value>: Integer or real

Value to add.
If a value is already present for a position in time, this value will be replaced with the new value.

Remarks

This function allows you to add data to charts that use a time scale and also to real-time charts. For more details, see Real-time chart.
