# Select-a-Chart Period

Charts based on your stations readings
All charts are zoomable

The Select-a-chart allows you to configure your own graph to compare values together. You can select start and end dates for the data. Up to six different data values can be selected using the drop-down selectors below the graph. Each data value has a further drop-down selector to change the colour for that particular data plot. You can edit the colours in the file 'lib/highcharts/ow-theme.js'.
