About Horizontal Point Line

[elmec]

There is no Horizontal Point Line,
so I using the Horizontal Line, and set the Pointer as visible,
change the transparency to 100 to hide the line between pointer
to make it look like as pointer series.

But just like shown in the attachment,
when there are a lot of points ,
they are drawed overlaping each other, so cannt be shown clearly.
When I zoom in the series, it became clearly drawed.

Do you have any ideas to draw all the pointer in like some "Merge" mode?

BTW, We are using the newest Teechart (201308) version for XE4 Firemonkey HD App.

Do you have any ideas to draw all the pointer in like some "Merge" mode?

Yes, you can do as in the All Features\Welcome\Functions\Extended\Reducing number of points example in the features demo, which uses TDownSampling function. Demo can be found at TeeChart's program group.

Hello Narcís,
Thanks for your advice.
Is there any other way to draw all the points clearly?

Hi elmec,

You can either set pointer style to small dots:

Code: Select all

  Series1.Pointer.Style:=psSmallDot;

Or make pointers smaller:

Code: Select all

  Series1.Pointer.VertSize:=1;
  Series1.Pointer.HorizSize:=1;

[elmec]

The attachment I have attached was the result after

Code: Select all

  Series1.Pointer.VertSize:=1;
  Series1.Pointer.HorizSize:=1;

So, I tried to

Code: Select all

Series1.Pointer.Style:=psSmallDot;

but all of the points diappeared...

BTW, I am using XE4 Firemonkey HD APP.

Hi elmec,

This looks like a bug to me. Could you please add it to bugzilla? Doing so you'll be identified as the creator of the issue and therefore notified about its evolution.

Thanks in advance.

[elmec]

Anyway, I'll attach the example project.

I have add it to Bugzilla.

Bug 93 has been added to the database...

[Narcís]

Thanks elmec,

That's the bug: ID93. There's a problem with the bottom axis range. Commenting out the line below points are visible.

Code: Select all

	//Chart1->BottomAxis->SetMinMax(-0.3, 0.3);

[elmec]

I think that's not the cause of problem..
The values are between the range I set,
why cannt I fix the range of Y axis (Bottom Axis for Horizontal Line)?

Hello elmec,

If none of the options suggested works fit your needs, you could try using a Bubble series with very small radius.

Hello Narcís ,

Thanks for your advice.
We'll have a try of Bubble Sereis.

But please let us know if the problem has any new status.
