Hi folks, I am planning to re-write a data viewer program I wrote ages ago using C + Xlib.
This program allows me to plot on the same window several graphs (time versus brightness - I work on variable stars). They all share the same independent variable (time passes the same for everybody). I can scroll and zoom the graphs both in X and Y. When I scroll/zoom in X all plots suffer the same action. Y scrolling/zooming may be done for each plot. Now the question: I need a data cursor, by that I mean some marker that sits on top of a point and which may be moved forward/backward by pressing a key. Matplotlib has a mouse cursor that gives me the cursor coordinates, but it doesn't - sit on top of my points and therefore doesn't give me the exact value of that point - allow me to move from one point to the next - allow me to change which graph I want the cursor sitting on I thought of drawing my own cursor, deleting it and moving to the next point . It seems this would take forever as (far as I understand) matplotlib will redo the entire plot each time I do this. How hard is it for the developers to include a built in data cursor in a similar fashion to the mouse cursor now available. I am affraid this isn't too easy, I don't know any plotting program that has one like what I need. thanks for your attention, Antonio Kanaan ------------------------------------------------------------------------- Take Surveys.
