Graph -> append to graph -> Category plot, and select only Y. I am looking for recommendations for free software to plot the results.įrom memory the increment in recorded height differences is 10cm and there are large swathes of 'unused' height differences, I think it might be better to plot only the recorded height differences on the x axis rather than plot every plausible value. Review and cite IGOR PRO protocol, troubleshooting and other methodology information Contact experts in IGOR PRO to get answers. Right-click (or control-click on Macintosh). The name of a window is important because it is used to identify windows in commands. Igor automatically assigns graph names of the form Graph0. If you specify no title, Igor will choose an appropriate title based on the traces in the graph and the graph name. If Igor was already running, choose New Experiment from the File menu. Double-click on the Igor Pro application file on your hard disk. We will generate synthetic data and then manipulate it using sorting and curve fitting. I think I can come up with a script to count the number of occurrences of each height difference, if so I can create another csv which contains only the recorded height differences values and the number of times those values occur, this may drop the number of coordinate pairs to a few hundred or less. The name wave0 is not very descriptive, so well change it to position, since these values will represent positions. It is not used to identify wind ows and does not appear in the graph. Here, we will concentrate on the data analysis features of Igor Pro. Typing in that cell adds a new point to the end of the wave. The gray cell at the bottom of a column indicates the end of the wave. As expected/hoped-for the vast majority are concentrated near 0, zero. In Igor, each column corresponds to a one-dimensional wave (although it is also possible to display and edit 2-, 3-, and 4-dimensional waves in tables), and each wave has a well-defined length. Excluding obvious wonky values they range between +-300+ ft. It would be easy enough to do on paper if there were only a few flights logs but I have 2800+ flight logs and there are a great number of height differences values. To me "graph" means a line passing through or near the intersection of the coordinates. I would like to plot a graph of the number of times a given height difference occurs (y axis) against the corresponding recorded height difference (x axis). The 'column' was actually intended to 'measure' barometer 'drift' over the course of the flight but it is proving to have other uses as well. One of the columns represents the difference in height of the take off point and the landing point. I have a log'book' ( a csv) that summarises every flight for which I have a.
