title: Combined Column Graph and Line Graph with Different Y Axis
body: <p>Is it possible to create a combined column graph and line graph with different Y axis like you can in Excel? I want to automate the production of graphs where the line graph is the Good -Bad ratio and the bar graph is the percent of universe for the given interval of another variable. The left Y axis would be for the Good - Bad ratio and the right Y axis would be the percent of universe. I'd like to do this with lattice but any recommendations would be appreciated. </p>
