Hello,

We are checking this. Could you confirm please, that the issue only appeared with 4.2022.2.28 and the previous build number that you used that didn't display the problem if that is the case.

With thanks.

Hello Yoni, Please take a look at the PaintPicture method in this example: https://github.com/Steema/TeeGrid-VCL-FMX-Samples/tree/master/demos/VirtualData/TStringGrid The handler is setup to act upon the data for the column, in this case to handle an image; but the approach can be used to handle dif...

Hello, Apologies for the delay, I see this post was missed. You likely have found the solution but here are details of how the connection can be made: See the example here: https://github.com/Steema/TeeGrid-NET-Samples/tree/main/WinForms/NET%20Framework/Cell%20Editors Form1 includes a method to conn...

Hello, Example: //set with: teeGrid1.Selected.Changed += Selected_Changed; //example event code private void Selected_Changed(object sender, EventArgs e) { var selection = sender as GridSelection; if (selection.Column == teeGrid1.Columns[0] && selection.Row != 5) { MessageBox.Show($"You've clicked a...

Hello Bruce, This example would go some way to the goal, proof of concept. You can make adjustments as necessary: procedure TForm1.Chart1AfterDraw(Sender: TObject); var i : Integer; myPoints : Array of TPoint; begin Chart1.Canvas.Brush.Gradient.StartColor := clRed; //can use (a)rgb colours Chart1.Ca...

Hello,

I've added that as a bug for investigation:

This may take us some time. The normal route to Linux that we recommend for TeeGrid is via Firemonkey; but we are looking at the code in Lazarus/Linux for options to compile.

Hello Bruce,

They'd be interesting plots for TeeChart. I've added them as a feature request. We'll take a look.

Hello Bruce, You could take the point values that you use to plot the data, converting them to pixel locations using: Series1.CalcXPosValue(value) and Series1.CalcYPosValue(value) ..or loop through the indexes of the points using: Series1.CalcXPos(idx) and Series1.CalcYPos(idx) ..and adding them to ...

Hello, You can set the colour as you add the data, using an rgb colour that matches the colour you require. eg. Series1.AddXY(50,50,'',rgb(128,107,45)); or change the colour after adding the data. Series1.ValueColor[1] := rgb(108,107,245); alternatively, if you're working with a datasource, you can ...

Hello, Is the test being run on an older PC? We can't reproduce the issue on straightforward tests. You can likely use the following two events and run a counter in there: procedure TForm1.Chart1MouseWheel(Sender: TObject; Shift: TShiftState; WheelDelta: Integer; MousePos: TPoint; var Handled: Boole...

Hello,

You may be better advised to check the mouse move/up event to register how the action took place. You could set a variable that is then used when the OnZoom event triggers.

Hello Willi, Yes, so this appears to be a Delphi issue, not related to TeeChart. The daylight changeover time coincides exactly with what would be, thus, an invalid date. If I take your routine and output the result to an edit box: procedure TForm1.Button3Click(Sender: TObject); Var Date_in_Text, Da...

Hello,

You need to load the supporting TeeChart package for Intraweb. YOu can download the most recent one here and update the references for your version of RAD Studio/Intraweb. See the readme.txt.

Hello Willi, Ok thanks for testing that. Using the original codeline, (tmpDate:=TTimeZone.Local.ToUniversalTime(AList[Index]);), are you able to break on the line and send tell us a value of AList[Index] that generates the ELocalTimeInvalid exception? ....or, better, if you're able to send us a smal...
