Event trigger on Data Series Visual change

[martyn73]

Is there an event trigger to detect when a user changes a visual property of a Data Series? (like the "Center price on scale" for example) It appears that when those visual properties are changed it does not trigger OnStateChange()

Hello martyn73,
Thanks for your post.

You would need to create your own logic to check if "Center on price scale"(or any other data series property) has been changed. You can use ChartBars.Properties.CenterPriceOnScale to access that property.

Yes, that's what I'm doing. I have added a custom checkbox on the chart trader panel to set this property value. But when you change the value from the data series window the OnStateChange does not trigger so I can't update my custom checkbox right away.

Right now I have added the code below in the OnRender method which still can cause a delay of the checkbox updating. And it's probably not the best place to put this logic either.

if(ChartBars != null)
{
if (ChartBars.Properties.CenterPriceOnScale)
{
if(this.cbCenter != null)
if (this.cbCenter.IsChecked == false)
this.cbCenter.IsChecked = true;
}
else
{
if (this.cbCenter != null)
if (this.cbCenter.IsChecked == true)
this.cbCenter.IsChecked = false;
}
}

Is there anything else I can monitor when visual properties in the data series windows are updated?

martyn73,

Nothing I can think of at the moment. I will keep looking into this though.
