Introducing a Flex Charting trend line component
How to draw trend lines on Flex Charts? Actually, you just have to add the trendline drawer component on the annotation section of your charts.
...
Now you can call method like drawLinearTrend() or drawPolynomialTrend(). It’s that easy and should work with all cartesian charts (column / bar / plot etc…) without extra work.
Have a look here for a demo. View source enabled.
Let us know for any trouble. Huge credits to the as3mathlib for the maths.
We don’t stop to add features like this in Bime so if you are interested in, register above to the Beta. It should come very soon: jump on the bandwagon!
Thanks for the great example code. This was exactly what I was looking for.
Dear, i can not draw the line when i change the TrendLineDrawer.mxml file below . before >>> after >>> i would like you to show the reason . thanks .
This is wonderful! I am curious though, is there a way to modify the drawRegressionLine function to refer to a chart’s ColumnSet instead of the chart’s series?
Can we draw a trend in dotted and can we draw a line according to the specific value in the y axis of the graph.
Please reply Urgent!!.
Thanks in advance
Hi – First of all thanks for the great code. I was exactly looking for it. How can we add best fit, exponential, logarithmic etc. to this? Please help.
