I need a heat map generated by points value irrespective of how close or far apart the points may be in QGIS 2.6.1 So far I'm using the raster/heatmap/heatmap function. I need the same colour to run through all the points of the same value. 

From the heatmap dialog, i'm using "use weight from field" which points to the right attribute, but I'm not getting the right result. As you can see this image shows that the heatmap that is generated has the same colour that runs through different values so it can't be right.

How do i get a heat map that is NOT controlled by point-density
