Re: Using DBChart with text data

Hello Errol, Yes, you could use code similar to this: var vals : array of double; i : Integer; begin SetLength(vals, 8); for i := 0 to 7 do vals[i] := Random(10); Series1.AddArray(vals); end; You could send x and y arrays to the method: ie. Series1.AddArray(xVals,yVals); Regards, Marc

Re: Faster Zoom

Hello,

There is no single property that will speed that up. It may be worth paying attention to factors of the Chart setup, ie. if any part of the chart has extra processing code on repaint that might be slowing down the paint cycle.

Re: OutOfMemory exception with nearly identical Y values (could be related to Bug 2267)

There is an interesting solution to the limitation, offered by Yeray for the ActiveX version of TeeChart:

Re: OutOfMemory exception with nearly identical Y values (could be related to Bug 2267)

Hello, Yes, this is, I think, related to precision of the double type itself. The problem of a large number with a small fraction. For example this fails to find a correct Axis increment: Series1.AddXY(7219300,282842.700000000032); Series1.AddXY(7219500,282842.700000000064); But this is ok (with the...

Re: Horz labels dropping

Hello Ed, Re.1. You can manually override the auto-separation with the increment property. eg. (you'll notice the effect of this test more on a horizontal axis but the result is the same on a vertical axis where you have multiline labels): Series1.Add(4,'first long long label'); Series1.Add(5,'secon...

Re: Marks not working as expected with TChartShapes

Hello,

Sorry for the delay with this reply.

You could set the text for the shape and leave Marks.Visible False.

eg.

Code: Select all

Series.Font.Color := clWhite;
Series.Text.Add('my text');
