Please,show the code that you are trying to use.  Without seeing what you are doing, it is very difficult to guess what could be wrong.

The table structure is :
Field1, Number, double.
Field8, Number, double

Steps I'm doing.
1. Create a form
2. Insert Chart using de chart wizard
3. Select table, select field1, field8
4. Select XY(Scatter) Chart
5. In the Axis X I move field1 (In summarize I select, none)
6. In the Axis Y I move field8 (In summarize I select, none)
7. Finish

Now I'm in desing view of the form
Double click over the chart
Click on the icon "By column"

If I look at the Form-Datacheet it only has 3999 rows

I'll try to attach the access file

My guess would be that there is a FUNDAMENTAL, built-in limit in the control at 4000 datapoints.  That seems to be a "reasonable' limit (I know that is not what you want to hear, but 120,000 points seems to me to be rather excessive - I used to work for the #1 Computer Graphics software company in the WORLD - back in the 1980's, and that company no longer exists), but I can tell you that 120,000 points would have absolutely swamped the graphics engine that we had built, and I suspect that may still be the case, for FREE components - and since you are using the Chart Wizard, you are, necessarily using a FREE component.  To get more points, you may need to invest *significant* $$$ and purchase a specialty graphics package.

sorry to not be able to offer a more hopeful opinion, but remember that here, as elsewhere, you generally get what you *pay* for - and FREE usually comes with significant limits.

It's the first time I come here. I think your comment is very useful but I would like to know if your remarks about *FREE* mean if I got points in this web page I'w get another answer that can solve my problem?

Thanks a lot.

no, I am talking about the price you paid for the CONTROL. not for the answer, that I have given you.  After all, with 500 points and $4.50 US I can buy a Tall Mocha Latte at Starbucks Coffee House (exactly the same price with 0 points---Points are not worth anythin to me, so I give the same answer for 50 points as for 500 points).

what I meant by "To get more points, you may need to invest *significant* $$$ and purchase a specialty graphics package." was: to get more PLOTTED POINTS on your scatter-graph, not more EE points.
