Re: Custom Drawing "On Top" of Series Lines...how to change...

BeforeDrawSeries event handle's it perfectly. So the way the events are named means this - "DrawCustomStuffBeforeDrawSeries"

Custom Drawing "On Top" of Series Lines...how to change...

I do custom drawing on the "afterdraw" event and the custom lines are drawing on top of the fastline series in my chart. The series data is more important than the custom drawing lines so I want those on top. Is there any way to have the custom drawn lines not overwrite the series data??? Thanks in ...

Re: Bollinger Function Leaves Bottom Line when Unselected

No reply so what I did was improvise -- I debugged and found that after a price is added to a Bollinger Function Series it creates a new unnamed series that has .ShowInLegend set to false and has a title of fastLine2. So after adding data to a Bollinger Series I do this: line_tcBollingerID.CheckData...

Bollinger Function Leaves Bottom Line when Unselected

I added a Bollinger function to a candle series on my TChart .Net chart --
When I uncheck the Bollinger series from the chart legend only the Top Bollinger line disappears - but the bottom line remains...
Aren't both Bollinger supposed to disappear?
Thanks in advance for your help.

Re: Easy way to Move Series in front of Another

Hi Yeray -- I think this is the same as just adding the series to the chart in a different order. All my code that is array based will still have to be modified. I was hoping for an answer that wouldn't require change all my array based index code. Such as Series1.ZOrder = 0 or something like that. ...

I know I can recode and the series in a different order but I do a lot of index based updates and such and would rather not have to change that. is there a Z-Orde...

Draw Multiple Transparent Bands with DateTime Bottom Axis

I'm trying to create transparent "highlight" bands on my chart to show important times. Bottom axis is a datetime axis. I have two issues -- #1) The Custom_Paint.htm example only draws one band and I need to draw multiple how would I draw multiples? #2) How do I map a date onto the bottom axis to ge...

Re: Add A Single Date, Value point to a Tee.Line object

I looked in datetime.htm in the examples and saw something similar -- Let me know if there's a better way but this will work-- function CreateChart() { Chart1 = new Tee.Chart("canvas"); Chart1.axes.left.title.text = "Value"; Chart1.axes.bottom.title.text = "DateTime"; var tlForecast = new Tee.Line()...

Add A Single Date, Value point to a Tee.Line object

I looked at all the examples and they use AddRandom or pre-populate with Arrays or TextBoxes and such -- I pull a JSON array from a web service then need to iterate through the array and add the values to a Tee.Line object below. The reason I don't just set the array as a datasource is it has many f...

Teechart Can't Handle Dates less than 1900???

DrawingBackwards.png I sell forecasts online and use this chart -- everything's been fine. I created a forecast and dates dip into the 1800's and everything printed backwards on the chart. Here's test code to show the problem: vb.net Dim dtTest as DateTime dtTest = CDate("1/1/1809 2:00 am") Me.TCha...
