Hi
I am using a heatmap in one of my visualisations and I want to know what I'm doing wrong. I want to modify the standard colour palette;
![clipboard_image_1.png clipboard_image_1.png](https://community.qlik.com/t5/image/serverpage/image-id/49282iEAB8334CFA6CE378/image-size/small?v=v2&px=200)
I thought I could do this by editing the json file where the colours are expressed in HEX format. When I do this, republish and select the heatmap visualisation - the control no longer works.
Is there something else I need to do to the json file in addition to adding the new colours I'm after?
Thanks
