problems with logarithmic chart using curvefitting

BlueMonkey · Post by **BlueMonkey** » Mon Dec 29, 2008 9:40 pm

I am using BDS 2006 and TeeChart 8.1

I have uploaded my application to your site with the name Bluemonkey1.zip. It demonstrates 3 problems.

1. Scrolling chart causes unexpected jump. You must cancel zoom to return to original display of chart.
2. Point series marks are visible outside the chart. (scroll up or down).
3. The logarithmic axis does not display axis labels between zero and 1,000.

Thanks,
Kent

Hi Kent,

where have you upload the demo project ? I've not found at steema.public.attachments newsgroup neither into the upload page.

I posted to the www.steema.net/upload page. That link was provided in another forum posting.

My company's IT group does not allow us to use newsgroups. If the upload page did not work, can you provide an ftp site?

Thanks,
Kent

Hi Kent,

ok, now I've found it. I'm investigating all your problems, I'll back to you asap.
About 2) You can clip the Marks by using Series1.Marks.Clip:=true;

I tried your suggestion for clipping the marks. I was able to successfully hide the rectangle and the label inside the marks, but the shadow still appears outside the chart area. I tried series.marks.shadow.clip := true, but that had no effect. Is there another property that I must set to clip the shadow?

Hi BlueMonkey,

The only solution I can think of is making marks shadow not visible:

Code: Select all

  Series1.Marks.Shadow.Visible:=false;

I'll add this to the wish-list to be enhanced for next releases.

Hi BlueMonkey,

About the other questions:

1. Scrolling the chart causes unexpected jump. You must cancel zoom to return to original display of chart. Logarithmic axes need to be enhanced and we have several aspects of this in the wish-list to improve for future releases.

3. The logarithmic axis does not display axis labels between zero and 1,000. If you set a logarithmic scale with base 10 you'll get 1, 10, 100, 1000, ... labels. Otherwise you'll have to add them manually using custom labels as shown in the All Features\Welcome!\Axes\Labels\Custom Labels example in the new features demo, available at TeeChart's program group.

I tried hiding the mark's shadow completely as suggested, but this does not work. There is no way to suppress the shadow.

DataSeries.Marks.Clip := true;
DataSeries.Marks.Shadow.Clip := true;
DataSeries.Marks.Shadow.Visible := false;

Hi BlueMonkey,

This works fine for me here using v8.04, which is the latest version available at the client area. Could you please check if v8.04 solves the problem for you?

Thanks in advance.

I am using build 8.04.11395. It does not work for me in the demo program that I sent to you previously.
