Help with Heat Map

Hi,

I am currently working on requirement where we need a Heat Map. I am currently using Table Heat Map 3.5.0 ( Custom Visual)

1. Firstly,  COuld you please recomend any other Table heat map if any. (no license). 

2. As per the image below(image-1),  I am unable to round the values to round 2 decimals. (Note: I tried to round the values by selecting the measures and format to 2 decimal in format tab. The result still appears to not turn the values to 2 decimal. 

3.  I would like to turn the current heat map as below(Image-2). For some reason it is not even allowing me to change the colors too. (Image-2). Tried options like Colorbrewer. It only has custom colors and it does not allow me to select any colors as we wanted as per image -2. 

Image- 1

Image - 2 (expected output)

Would really appreciate your time and help. 

Thanks and Regards
