Hi Narcís,

Yep, I was too much in a hurry.
Now it works fine!

Many thanks, Cock

Hi Narcís, Thanks for your quick reply, however I think I was not very clear with my question. The area I would like to have transparent is not the whole chart, but the area wich you select in the ChartEditor --> Panel --> BackGround. (Also in the ChartEditor -->Walls -->Back -->Color := clWhite, Vi...

Hi,

I'm using D7 with TeeChart Pro 7.07

Is there a trick or property somewhere to set the Panel --> Background to transparent?
I can't see it in the properties, or do I miss something?

Thanks in advance for your help,

Kind regards, Cock

Hi Yeray,

Thanks for your idea's. They have stimulated my creativity!

As there is a running timer in the application for observing and processing data acquisition data, I can use this timer as well for slowing down repaints when customer is teasing the application.

Kind regards,

Davy

Hi Narcis,

Have installed binary release 7.07 and there is no enhancement of the performance.

Hi Narcis, Thanks for your reply. I assume that this code is the same as you propose: if (ssRight in Shift) then Chart1.AllowPanning := pmNone else Chart1.AllowPanning := pmVertical; This code just disable scrolling at all, which is not our goal. Customer should be able to Pan, but without excessive...

Hi, Using TeeChart 7.04 I've created a 1000 points sweepchart which cycles around when at the end of data. In 'RealTime', a point in a serie is replaced. This works very well, with a total processorload of 0 - 2 % for the whole data acquisition application. The customer is able to scroll (pan) only ...

Hi Pep,

To be more complete:
ChartGrid1.OnKeyDown if Key = VK_DOWN --> - GoEditing
ChartGrid1.OnKeyUp if Key = VK_DOWN --> + GoEditing

However, do you publish a list when upgrading the product, describing changes on undocumented features like this one or dotted line series?

Hi, TChart 7.04 I'm using a ChartGrid, connected to a Chart --> Series1. Series1.FillSampleValues(20); So far so good. However, when I click on the ChartGrid and hold down the DOWN KEY, the ChartGrid starts scrolling beyond the size of the Series1, i.e. points (zeroos) are appended to the Series1. I...

Hi Narcis,

I have not seen any reply to my last message yet, therefore again:

I think it is a bit of un-intended behavior of the chart, because FillSampleValues does what it should do. Could Steema address this please?

Kind regards,

Davy

Hi Narcis, Playing around with pen styles and so on does not makes any sense in this application. Infact, the graph is used as a sweepchart with a pre-defined no of points, where every 200 ms a point is overwritten with a new one, so the graph cycles around every 2000 / 5 = 400 seconds. It is an dat...

Hi Narcis, Have tried your code with 7.04 and that works well indeed. My code is a bit different as you might assume Note when zooming in you see a dotted line between points. procedure TForm1.Button2Click(Sender: TObject); // This code does not draw a dotted line var i: integer; j: double; begin fo...

Hi, I have created a chart, TeeChart 7.02, drawing 2 TLineSeries, each line is about 2000 points. One of them needs to be dotted or dashed style. When setting TLinePen to dotted (small dots True), you don't see a dotted line because the dots are drawn between points. And with 2000 points in a trace,...
