Like I said this is a simple demo of a much more complex situation. I really don't want to chase down every little item to show you that I really need to call the .draw command. I do--because the positioning of the legend needs more than just a margin begin set. To set the position of the legend, I ...

Sigh. If I remove the .Draw command the custom positioned legend does not work. (This was told to do this by Steema's support).

Please let me know how to move forward.

I hope you have (or had as your probably wont' get to this in 2016) an wonderful New Years and that 2017 is a great year for your. I appreciate your attention to this issue. After reviewing my code I didn't t understand what is happening--you are correct (as you know) that the demo does not work in ...

This was only a demo. The actual chart is created in a data module (so "self" does not work) and I also use this in a online service and would prefer not have to create a TForm.

This wasn't this way in 2015.x.

Can this be fixed?

Attached is a demo that creates the problem. (I just tested 2016.18 and it worked fine. It only seems to occur in .19).

I just upgraded to 2016.19.161025 and I get an exception (Control 'chartTest' has no parent window) for a chart I create fully in code. It occurs when I call the .Draw method. I will post an example here soon but I sure would like to have a fix to this ASAP.

Couple items: 1.The donut example doesn't look like it gets very close (does it do 180 degrees, support in-series labels?), and the gauges example is lacking as well (no labels). 2. I do not have an "examples" directory. I installed the source code version. I also searched your website and did not s...

I need to create a chart that looks something like this:



The pointer on at ~2 o'clock indicates their position (117 out of 150).

Can that be done with a TChart series? If so, how?

Much appreciated,

In the attached (very simplified) demo of a project I am working on, I add bands to the chart when I load the data to the grid. Problem is, I don't know when I can add the bands: when I add the bands, I need value for Chart1.BottomAxis.Maximum. If I add the bands in OnBeforeDrawChart, Maximum is 0, ...

FYI: I just installed 2016.19 for Seattle (wanting to move my project to Berlin update 2 but have a bit of work to do to get there). When I compile my project, I get the following warnings: [dcc32 Hint] H2161 Warning: Duplicate resource: Type 2 (BITMAP), ID TANNOTATIONTOOL; File D:\DelphiComps\TeeCh...

I am adding a band to a chart as soon as the user clicks on the chart--and I want to start resizing the band as soon as it is added. Can that be done?

Thanks

When the mouse is moving over a chart, I want to get the corresponding value of the axis--the opposite of CalcXPosValue.

How do I do that?

Thanks,

Is there an easy way to make the legend only show one decimal point when the TextStyle = ltsLeftPercent? By default, it shows 2.

Thank you,

Delphi Seattle, TChart Pro 2015.16 I need to create a custom legend. The chart only has one bar series, but negative values are displayed in red (additional lump savings needed for today) and represent a different value than positive value (cash balance at life expectancy). How can I in code create ...
