I am looking for help in compiling the data from multiple studies using different statistical values to make a graphic combining this data. I would like to also be taught how it was done so that I may become proficient in doing so. I am looking for simple X and Y-axis graphs, nothing extravagant. I do not have access to the data that the studies used to make their tables and charts, so I am not even sure this is possible (is it?). I have tried self-teaching using SPSS and excel, but have been struggling.
