We have a line graph which plots the actual data points (x,y), everything is working fine with this graph. Now we need to add a trend line to this existing graph after going thro. the articles we came to know that there is no direct option in SSRS to draw a trend line. So we need to calculate the trend values ourselves which we need to plot as atrend line. This trend line is similar to the trend line which comes in Excel chart, do anyone know how to calculate the trend values from the actual data points. We got through several formulas, but were not clear, have anyone tried out exactly the same, if so please help us out by providing an example to calculate the trend values.
The default functionality of Reporting Services does not support trend lines. There are some additional tools you can purchase to achieve this though, which is talked about in the first link below.
