DashPattern restarts at every new point?

Post by Aaron Peronto » Thu Apr 12, 2007 2:48 pm

In the plots that we are generating, we are using several characteristics to distinguish between plotted series that belong to separate datasets.
One of those characteristics is the LinePen.Style (and the LinePen.DashPattern setting for custom patterns).
What I am seeing is that when I am not zoomed in on some of our plots, the points appear so clost together and the DashPattern is restarting at each point so all lines really just look like solid lines.
When you zoom in far enough, it becomes easier to see the difference between the lines since there is more screen space between each point for the DashPattern to be used.

Is there any way to prevent this restarting of the DashPattern at each point that is drawn for a series? This way, even at the fully zoomed out view, there would an obvious use of the Dash-Dot-Dot pattern (or whatever happens to be the current pattern) repeating across the entire length of the plotted series and not just appearing like a solid line since there is not enough screen space between points to render the pattern fully before it restarts.

Let me know if this doesn't make sense.
I can provide some screen shots that demonstrate the appearance that I am referring to.

Thanks.

Hi Aaron

We couldn't reproduce the problem, could you please send us a simple example project we can run "as-is" to reproduce it here?

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

Thanks in advance
Best Regards,
Edu

I will see if I can get you something that demonstrates this.
The problem will be in the fact that it shows up when the data sample interval is small so I will have to try to get you something that creates a dataset that shows this behavior when combined with the non-solid line styles.

I will work on providing a sample when possible.
Thanks for looking into it.
