Re: Set Axis and Zoom in Form Load Wonky
Hi Marc, I tried the AfterDraw code change you suggested and the Zoom still doesn't work. I tried messing around a little bit with UndoZoom first and DoEvents but still no Zoom using AfterDraw. I've attached my code in case that's helpful and have the whole VS 2019 Project with just the repro code i...

Set Axis and Zoom in Form Load Wonky
Hi Steema - I'm building an app and trying to set the TChart Axes and Zoom during form Load - The Set Axes works but not the Zoom - But if I set the Axes and Zoom with the same code from buttons on the form once loaded it works. I'm sure it's an event sequencing issue of some sort but can't figure i...

Read Zoomed Values
Hi Steema,
When I zoom into a chart I'd like to get the zoomed MinX , MinY, MaxX, and MaxY values and thought it would be in the Zoomed event but am finding it challenging to figure this out. Please see attached screenshots. I'm doing something wrong.
Thanks as always!
Joseph

Iterate through Chart and Scrape Bollinger Upper, Lower, and Middle Band Values???
Hi Steema Techs,
I would like to iterate through all the Values on a chart and Scrape the Bollinger Values for Upper, Lower, and Middle band as well as Date.
Do you have any sample code anywhere that shows how to do this?
I only see X and Y values.
Thanks so much,
Joseph

Re: TChart for .NET Disappearing from Designer
I rebooted and the problem seems to have disappeared. Apparently my system was flaky — thanks, as always, for your lightning support!

TChart for .NET Disappearing from Designer
My TChart keeps disappearing from the Designer in Visual Studio 2022 Community Edition whenever I close the Designer and ReOpen it. I'm running .NET 5.0 framework. I've used TChart for years and have never seen this behavior. Any ideas on how to make the chart stay put? Thanks, Joseph https://i.post...

Re: Programmatically Creating DrawLineItem Error Null Handles Exception
Christopher - u r correct! I feel dumb for missing the constructor that takes the drawline object as a param.

Programmatically Creating DrawLineItem Error Null Handles Exception
I'm adding DrawLineItems to the Lines collection and that's fine -- Until the chart tries to refresh and throws an exception because all the "Handles" fields such as EndHandle, MidlleBottomHandle, MiddleTopHandle, and Starthandle are Null so a NullReferenceException is thrown. My question is how to ...

Hi All -- Love the DrawLines class never used it before. I have a list on the screen where I have a list of DrawLineItems on chart. I want to be able to click on a line item in my list and have that line become "selected" on the chart -- as if I clicked on the line itself. Is there some way to do th...
