Chart printing: stepped appearence

Messie · Post by **Messie** » Tue Mar 04, 2008 10:06 am

Hi,

when I print my chart, I see steps which do not refer to the real data.
To check if it is a printer settings problem, I saved the metafile (printed with stretchdraw). The metafile shows the same problem.
So how do I get to a proper printed chart?

Thanks, Messie

Hi Messie,

I'm sorry but I don't understand which is your exact problem. Could you please send us a simple example project we can run "as-is" to reproduce the problem here?

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi,

It is a bit tricky to post a simple example but I sent the metafile. The chart is designed at runtime as well as the parent form.

Thera are data points each 10°C where the y-axis data is raising smoothly

meanwhile I extracted and uploaded parts of the function. Maybe this way you can see which settings are wrong.

Hi,

any suggestions what might be the reason? I loaded the data into another chart which was prepared at designtime and the exported metafile looks quite better. I can'T find out why the chart created at runtime is so different.
Is there any possibility to export all the chart settings?

Thanks, Messie

Hi Messie,

it's a strange. The problem is that it's difficult to know where is the problem entering the data at runtime.
A good test would be to add the data via code, and then try to print the Chart.
About the Chart settings, you can export the chart through the Chart editor (at runtime for example) , from the Export tab, select Native, and check as "text". This will allow you to edit the .tee file and check all the chart settings.

If you still having problems, please send us a sample images of what you should get, the result you're getting and a file with the data you're trying to populate so we can try to reproduce the problem here.

Hi Pep.

meanwhile I found out that there is no real difference between the runtime and the designtime chart but the size. So I enlarged the runtime chart to width>5000 Pixel and the printing is fine now.
It looks like the chart resolution is not good. If I display the form with runtime chart, the stepping is visible, too. So what can I do to increase the displayed resolution? Does the Chart.Printresolution or the resolution of the standard printer have any influence?

I would like to get a higher resolution in display and printing without increasing the chart like that.

Thanks, Messie

Hi Messie,

I've just send you an example project and a document on how to print better with TeeChart.

Hope this helps!
