Thanks Eugene, Here is the work flow (keeping the rainfall example going): 1) drag month onto x 2) drag long-term rainfall data on y 3) right click points -> change to bar 4) right click bar -> add -> error bars -> standard error So far so good. But, this is where I get stuck: 5) drag rainfall data from a single year (the one I want to be represented by a line) onto the y axis and it displays as a second bar series, (and also adds error bars of 0) 6) if I right click on the second series -> bar -> change to line, both series get changed to line So my question is how do I change just one series to line (with no se bars), while keeping the other as bars (with se bars)?
Graph builder is a "quick and dirty" way to rapidly explore data graphically. Use the "Chart" platform if you want to make this combined plot manually.
Enter Month and your two Y variables, and make sure "Overlay" is checked and also check "Add error bars to mean". In the legend of the resulting graph, right-click on one variable and change to "Line chart".
And, btw, the scripting in JMP is what sets it apart. You don't have to learn much actual scripting (like in R). Most of the things you do manually can be saved as a script for repeated use. Yet, JMP scripting, can be very powerful.
But if it's just neat graphs you are looking for, JMP may not be for you.
