I have been trying to generate heatmap using kernel density estimation from python console in QGIS.
This is command i'm using:
processing.runandload("saga:kerneldensityestimation", "D:/test/Towns.shp", "A_RAIN_MM", radius, 0, "0,1,0,1", 0.00848754, "D:/test/raster.tif")
The result I'm getting is a image with black shade which is totally different from the heatmap i generated using QGIS user interface.
After googling, I found this link:
kernel density estimation. This contains the list of parameters which kernel density estimation takes, but it does not contains any description about the parameters. What these parameters are i do not know. Can i anyone tell me what i'm doing wrong? Or is there another way of generating heatmap?

I think you need to replace your
radius
parameter with a number.Incase this might help for future reference, what I usually do when I need to know what parameters I have to set, is to check the "help" details of the algorithm within Python Console (Plugins > Python Console). Type the first 2 lines below:
