How to make a geographic heatmap ? If its not possible, how to create a heatmap chart based on average data of each of my variable?

So these are the river that flows from upstream to downstream. And the attachment files are the heavy metals concentration of each station. Is it possible to create a geographic heatmap based on the average concentration of the heavy metals concentration, according to its date taken? I want to show which station along the river have the highest and lowest concentration of heavy metals. And also I didn't found yet any geograpic heatmap analysis in MATLAB for this kind of heatmap. And if its not possible, how to create a heatmap chart same as what i mentioned just now, but not in geographic heatmap, just heatmap chart?

Oh im sorry, not average value, but point data according to its date. I want to show the heatmap of the concentration of heavy metals on each station from 37 until 1, not including the costal areas (B1 - D4).

Hello Isyraf,
I understand that you are interested in creating a geographic heatmap based on your data. If that is not possible, you would like to create just the heatmap chart without the geographic map.
I suggest you try using functions such as 'geobubble', 'geodensityplot', 'geoplot', 'geoscatter', or 'geodensityplot' to achieve your desired visualization. I recommend you refer to the following documentation for more details on visualizing data on maps:
https://www.mathworks.com/help/matlab/geographic-plots.html
I came across a similar question in the MATLAB community that provides detailed examples on how to create a heatmap. I recommend referring to the answer in the following link for more information: https://www.mathworks.com/matlabcentral/answers/722079-generate-a-geographical-heat-map
I hope this helps.
