Workaround

After carefully considering the severity and frequency of the issue, and the cost and risk of attempting a fix, it has been decided to not address this issue in any current or near future releases. We do not make this decision lightly, and we apologise for any inconvenience.
 
By default, there are 30 points in the trend. If system is too slow to render the 30 points, this could be customised setting the property "com.snc.pa.text.trendline_points_for.frequency" to 10 or 15. There will be less points but it will be faster to render.
