title: Google Charts, using multiple bar chart and dependent controls together
body: <p>I'm trying to make a bar chart using Google Charts with dependent controls. The problem I am having concerns inputting the data in a format that is usable for my task.</p>
  
  <p>Here is an example of the data I want to use: </p>
  
  <p>'Option1heading', 'Option2heading', 'Option3heading', 'val1', 'val2', 'val3', 'val4', 'val5', 'val6'</p>
  
  <p>'Row1val1', 'Row1val2', 'Row1val3', 1336060, 1538156, 1576579, 1600652, 1968113, 123345</p>
  
  <p>'Row2val1', 'Row2val2', 'Row2val3', 400361, 366849, 440514, 434552, 393032, 234374</p>
  
  <p>'Row3val1', 'Row3val2', 'Row3val3', 1001582, 1119450, 993360, 1004163, 979198, 578236</p>
  
  <p>'Row4val1', 'Row4val2', 'Row4val3', 997974, 941795, 930593, 897127, 108087, 4893</p>
  
  <p>The first row in this example contains the options that I want to filter on 'Option1heading', 'Option2heading' and 'Option3heading'. In reality these might be something like 'country', 'region', 'state'. The second row onwards then contains the data, 'Row1val1', 'Row1val2', 'Row1val3' being the filter information (e.g. 'France', 'North', 'Paris'). </p>
  
  <p>Following that, the 6 numeric values would be individual bars of data for that row. In the legend for this example these would equal 'val1' - 'val6' (as per the first row). In reality these might be things like 'population', 'Male', 'female', '0-10 years' etc. </p>
  
  <p>Here is the code as it currently stands. It 'kind of' works but is not working correctly. Is this even possible and can anyone point me in the right direction in order to do it?</p>
