Hi toolsops and alexantao,
well the docs are pretty strait forward on this and tell you what can or should be done.
To remove the error message you can:
Switch to a chart type that involves drawing only one shape per series (in other words, move from a column chart to a line chart).
Reduce the number of fields that are being plotted.
For time charts, use a longer time-span between data points.
There are additional conditions that can cause truncation:
Searches that return too many results per series can cause JSChart to hang the browser. Splunk employs a throttling strategy that restricts the number of results returned per series to 500 by default. You can configure this value by going to JSChart.conf and changing the maxResultsCount parameter to something other than 500.
JSChart can only plot the first 50 series that are returned. Additional series will not be plotted.
Object rendering limits by charting library. Both charting libraries have rendering limits if the total number of objects plotted in the chart exceeds a certain number. If you run into this limit you'll want to change either the search string or search time range so that the results returned fall under the limit.
For the FlashChart library, the rendering limit in all cases is 2000 objects. If you hit this limit, the chart stops rendering.
The JSChart library has a 2000 object limit for line and area charts, a 1200 object limit for bar, column, and scatter charts, and a 1000 object limit for charts displayed with Internet Explorer 8 or an earlier release of IE. If you hit the limit with a chart that uses JSChart, Splunk provides an error message.
Note: You can override the truncation limit for charts rendered with JSChart by changing the value of the charting.chart.resultTruncationLimit property on a per-chart basis. Note that this property is only available for panels rendered with JSChart. Also, be aware that increasing this truncation limit can have a negative effect on dashboard performance.
You can't change the FlashChart truncation limit of 2000 objects.
hope this helps ...
cheers, MuS
