Trying to get the axis bounding box

[Vivo]

How do I retreive the axis bounding box? I've tried to use the axis properties but they do not appear to give me the correct values.

Also, is there a detailed document stating what each interface function does? I see that not all of the functions are documented and it makes it slower going when I have to do trial and error to see what things do.


Thanks,

Hi Adrian,

You can use TChart1.ChartRect for that. The ChartRect function sets the Axis bounding rectangle adding the 3D percent offset in pixels to the Right and Top coordinates. It should be used before painting the Chart component to which you wish it to apply.

The bounding rectangle can be obtained via Axis Positions:

Code: Select all

TChart.Axis.Left.Position, 
TChart.Axis.Top.Position - TChart.Aspect.Height3D, 

TChart.Axis.Right.Position + TChart.Aspect.Width3D, 
TChart.Axis.Bottom.Position

Also, is there a detailed document stating what each interface function does? I see that not all of the functions are documented and it makes it slower going when I have to do trial and error to see what things do.

You can have a look at the help file and user guide at C:\Program Files\Steema Software\TeeChart Pro v7 ActiveX Control\Docs (default english installation path). Here you'll also find the tutorials which may be helpful for you.

Works great.

I've tried to use these before, but found it hard to navigate. Probably, because it required a basic understanding on how this COM component works. (i.e. no hierarchy or communication/interaction diagrams). It is getting easier as I go though. Do you have any basic UML Use Case Diagrams?

Thanks,

Hi Adrian,

I'm glad to hear that fits your needs.

We don't have any UML diagram but it can be really helpful reading the tutorials, having a look at the features demo, available at TeeChart's program group, looking at the FAQs and using those forums search feature.

Yeah, I'm doing that, but it is sometimes slow going when I am trying to figure out the full functionality of some class and how it relates to other classes as the demos usually only show a portion of what it can do. The same goes with the FAQs. I'm not saying that these are not invaluable tools; it is just that they can sometimes not be enough explanation.

And when I am looking for something specific, it can be difficult to find amongst all of the other things that the tutorial, demos and FAQs are showing. I will continue to plug away.

By the way, are you aware that if you have multiple vertical axes, each one having a label and you right click and drag up or down far enough, the labels will disappear from all of them at some point? This may have something to do with the labels all being at the same point on each respective axis (0.0), though all of the axes are not lined up at the same y position (i.e. y=0.0 of one axis is not the same physical ordinate as the y=0.0 of another axis). Looks like some sort of clipping problem.

Thanks for the help,

I couldn't reproduce the problem here. Could you please send us an example we can run "as-is" and the steps we should follow to reproduce the issue here?

Thanks in advance.
