Ok, I might understand what you are doing now. If you are populating one cell with the value "#FF0000" and hoping for it to turn red I am afraid that won't work. You will have to work with CSS and the style attribute.
Use something like style="background-color:#{!your_color_value}" in the tag displaying the cell that should have that background color.
style might not be accurate in this case. Check the Visualforce Component Reference to manipulate the right component. http://www.salesforce.com/us/developer/docs/pages/index_Left.htm#StartTopic=Content/pages_compref.htm

Hi,
You mean that you want to create a map in Apex?
See this page for explanation and examples:
http://www.salesforce.com/us/developer/docs/apexcode/Content/langCon_apex_collections_maps.htm
// Niklas
yes, I want to create using apex.
Well, then the provided link should give you a start. But for example you can do like this:
Map<String,String> theMap = new Map<String,String>();
theMap.put('Green','##00FF00'>;
theMap.put('Red','#FF0000'>
and so on. Then you can get either keys or values from the map.See all map methods here:

I want to create the heat map based on report data.
Sorry, you have to be more specific than that on what you want to accomplish.
// Niklas
I am creating a report and based on that I want create a heatmap. eg. like this,
Don't think it's possible to do that. There is no report object that I know of that can be used in Apex. Reports are just querying data so the best thing to do here is probably to create a SOQL query and put the resultset directly in to a map.
Ok. But I am not getting the color in table.It displays the value that I pass.I have used this code.
Map<String, String> hm = new Map<String, String>();
hm.put('P1','##0000A0');
It shows me ##0000A0 in table.
When using a map to get data from it, you will get the value using a key.
So if you call the map like this hm.get('P1') you will get the value of the key 'P1', i.e. '##0000A0'.
I am not sure I understand how your table is generated. You say it displays '##0000A0' in the table. How is this table generated? What do you want it to display?
I am creating table in pageblocktable and getting the value from the controoler in which I have created the MAP. My table should be:
P1
This cell shpuld be filled with RED color but it shows me the color value.
P2
This cell shpuld be filled with BLUE color

Can you please help to get me started with heat map implementation.
Thanks.
