Re: Stepping as stacked area series to/from zero values
Hello, Then, you want illustration #1 to look like in "method 2". Project1_2023-10-04_11-29-39.png The last down step in the red area is a problem? If it's a problem, how would you draw it? The sum of data at point x=22 is 9.163,97+8.906,34+815,17=18.885,48, while the sum of data at the last point (...

Re: Can't find a property for a color...
Hello John,
It could be the left and bottom axis pen, or it could be the back wall.
You can open the form in text mode and try to find what properties have you set in that chart at design-time.

Re: TeeGrid color questions
Hello,
You can use properties under
You can use properties under
Header.Format.Brush
. Note you may need to hide the Gradient so the Solid Brush can be drawn. Ie:
Code: Select all
TeeGrid1.Header.Format.Brush.Gradient.Hide;

Re: Posting marks left or right for a TPoint3DSeries
Hello Jan, I'm not sure how are you exactly drawing your TPoint3DSeries but here it is an example showing a simple one with all the points with the same XValue . Here what I'm getting: VerticalPoint3D_Marks.png uses TeEngine, Chart, TeePoin3; var Chart1: TChart; procedure TForm1.FormCreate(Sender: T...

Re: Font Sizes in Charts
I see removing the Showing condition at TCustomTeePanel.ChangeScale at {VCLTee.}TeeProcs.pas unit fixes it, but I have to check for any collateral damages: procedure TCustomTeePanel.ChangeScale(M, D: Integer{$IFDEF D24}; isDpiChange: Boolean{$ENDIF}); //... if not (csLoading in ComponentState) and ...

Re: TChart Line Chart Series with DrawStyle Curve Dips Below Zero - How to Fix?
Hello, I've tried with a custom cubic spline, but it doesn't give the result I'd expect: Project3_2023-09-12_12-21-08.png uses Chart, Series; var Chart1: TChart; type TCoeficient = record X, Y, b, c, d: Double; end; type TCoeficients = array of TCoeficient; type TPoints = array of TPointFloat; proce...

Re: Unable find mouse click event on rectangle
Hello, In that case you should do something like this in your event listener: const body = document.body; body.addEventListener('click', function(evt) { for (let i = 0; i < this.data.length-1; i++) { const x1 = this.axes.bottom.calc(this.data[i]); const x2 = this.axes.bottom.calc(this.data[i+1]); co...

Re: Unable find mouse click event on rectangle
Hello,
I'm not sure how are you exactly drawing those rectangles, but here's an example of detecting a mouse click on a drawn ellipse.

Re: TChart Line Chart Series with DrawStyle Curve Dips Below Zero - How to Fix?
Hello, I'd say this is something to expect if you want the curve to pass through the points. If you don't need the curve to pass though the points, you can use a TSmoothingFunction with Interpolate:=false as follows: uses Chart, Series, TeeSpline; var Chart1: TChart; procedure TForm1.FormCreate(Send...

Re: Design issue: use one tchart component or several?
Hello, That's an interesting design decision for your application that can be considered for any component, not just specifically for TeeChart. I'd say it's more elegant and consistent (and less error prone) to reuse a classes/components, but you will probably want to also consider the cost (time in...

Re: Legend box always truncate the last line....
Hello Tor, The line series is drawn as a line in the legend. This is the expected behaviour. You can fully customize the legend symbols as shown in the example here . Or, if you just want to show a square for a line series, you can "hack" it: just add an dummy bar series with no data; set its title ...

Hello, Sorry for the delayed reply here. Problem #1: Fonts are the wrong size: 1) Start the app on a monitor with normal DPI. The "Chart #1" tab page should be showing. 2) Without changing pages, drag the application to a monitor with 200% DPI. 3) Switch to the "Chart #2" tab page. You should see th...

Re: 'A class named TInvertFilter already exists' error in TeeChart Pro 2022.35
Hello Tammy, I previously was using the TeeChart that came with Rad11.3 Delphi, but couldn't access tech support or the forum unless I bought it directly from Steema. So I bought it, and downloaded the latest and now I just need to get some help on this (guidance or bug fix). We also give support th...
