programmatically change a charts dataseries

[KyleMcFar5]

Hello, right now i have an indicator/addon that changes settings at different times of the day, I'm looking to try changing the timeframe bartype when my indicator reloads the new settings for that time, I force a chart refresh via

private void TriggerChartRefresh()
{
    
            try
            {
            ChartControl.Dispatcher.InvokeAsync((System.Action)(() =>
            {
                
                    // remove keyboard focus
                    Keyboard.ClearFocus();

                    // explicitly give the chart focus
                    ChartControl.OwnerChart.Focus();

                    // send an F5 key event
                    Keyboard.FocusedElement.RaiseEvent(
                    new KeyEventArgs(Keyboard.PrimaryDevice, PresentationSource.FromVisual(ChartControl.OwnerChart), 0, Key.F5)
                    { RoutedEvent = Keyboard.PreviewKeyDownEvent });
                    

                    ForceRefresh(); // Perform chart refresh
                    
                  
            }));
            }​

I was wondering if I can do something like this

 if (State == State.?)
    {
        if (ChartControl != null && ChartControl.ChartBars != null)
        {
            ChartBars.BarsPeriod.BarsPeriodType = BarsPeriodType.Tick;  // Set to Tick bars
            ChartBars.BarsPeriod.Value = 100;  // Set the value to 100 ticks
        }
    }

or something like this

if (State == State.?)
    {
        // Access the current bars series
        BarsPeriod barsPeriod = BarsPeriod.Clone();

        // Modify the barsPeriod to the desired type and interval
        barsPeriod.BarsPeriodType = BarsPeriodType.Minute;  // Change to Minute bars
        barsPeriod.Value = 5;  // Set interval to 5 minutes

        // Apply the new bar period
        BarsPeriod = barsPeriod;
    }​

Hello KyleMcFar5,

You can find the default keyboard shortcuts for changing to various types of series in the following link, that would be the only way to change to other bars types from code.

As a side note ForceRefresh is not needed, changing the dataseries settings automatically reloads the chart. ForceRefresh if used for rendering purposes to mark that re rendering is needed, that has nothing to do with the chart loading.

ok i can make that work but what about for custom bartype or HA

Hello KyleMcFar5,

There would not be a way to do that programmatically, only the supported bars types with keyboard shortcuts could be used.
