missing value

hi,

I am using time series algorithm.and my prediction query is like this

SELECT PredictTimeSeries([Performance]) FROM [Stud_Model]

The output is like this

Date Perf

9/11/2006 90

10/11/2006 92

11/11/2006 93

12/11/2006 -- (no prediction)

1/11/2007 --(no prediction)

I dnt know why there is no prediction after certail date?

Thanks,

Karthik

The time series algorithm is based on regression trees which can become unstable as you move away from the time horizon, since you have predictions based on predictions. The algorithm tries to detect when this instability occurs and stops predicting at that point.

In future releases, we will have more user control over prediction stability and the behavior of the algorithm around this stability.

Missing Labels in Chart

I have a line chart that has several series, and it routinely leaves off 1 or 2 point labels on the last X-axis.

Is anyone else experiencing this? If so, does anyone know what the cause is, and is there a fix?

Thanks!

There is a setting in the X-Axis tab for major and minor interval. Try setting one of them to 1.|||

They are both set to 1 and still no labels.

I am missing point labels (on bar charts) too, seems to happen when there are an odd number of instances of a grouping on the x axis. It is always the last bar that is missing the point label too.

Is this a bug in SSRS, or a misunderstanding on my part?

One way around this is to turn on margins on the x-axis.
