Hello.

I've a chart with few Line series bound to DataSource. Works fine for small data amounts, however the problem appears when there is a lot of data to display. Chart becomes flooded with points, and it becomes imposible to see anything. I guess there should be some kind of option to skip few intermediate values to the point where chart is easy to read.

Thats probaly basic question, but I couldnt find solution myself.

Thanks.

Nick

Hello Nick,

There is an example which I would recommend you to try: http://www.devexpress.com/example=E452. Also, you can use the PointSeriesLabel.OverlappingOptions.ResolveOverlapping property, as it may be helpful in some cases.

Does this meet your needs?

Hi George, thanks for reply.

Unfortunatly, your advices did not help.  As I understand, both code examples are for removing Point labels. It doesnt help me, because I dont use point labels, so thats not a problem.

My chart becomes flooded with points. (Look at example in attachment)

I want it to be readalbe (for example it can be done by showing only every 3rd point, or every 4th and so on). Is there option for that ?

Hi Nick,

Thank you for providing the picture. Now, your task is much clearer to me. You can do the following:

First, change the Qualitative argument scale type to DateTime, to get a more distinct performance of X-axis labels.

As for data points, you should filter data at a datasource's level (by an appropriate SQL query), or by using a custom summary function.

Hope this helps you!

Hello George, thanks, that helped.
