VariablesSelect a variable by clicking on it. The pollutants available will depend on the selections of other parameters (e.g. site and date range selected). This tool is limited to plotting up to 10 variables together. To choose multiple variables, first select one then hold the CTRL key while selecting additional variables.
Date RangeChoose to enter either 'Specific Dates' or 'Specific Years'. 'Specific Dates' allow you to choose day, month and year to start and stop your analysis. 'Specific Years' will allow you to quickly choose the years of interest to you and the analysis will commence on 1st January and run until 31st December of those selected years. The Summary Plot tool is set to visualise the data based on whole years so either option will produce the same result for this tool.
