Hello, im currently working on data analysis with matplotlib and have some problems with the useage of the mousebuttons when using the ginput() function i actually have a long sequence of data on which i want to achiece 4 linear regressions, so my idea was to plot the data and choose the data points with help of ginput(8) so i can choose 8 points between which the data gets evaluated the problem is the big size of data so i have to zoom in and out between choosing 2 points. my problem is that the ginput function interprets the zoom in clicks as choosing a point from my data, i already tried to override the left mouse button to the ride button but it seems to me that it is online possible to switch the button configuration so that i have the mouse_pop function on the left mouse button and the mouse_pop function on the right side, but this doesnt help me either since each data point gets erased when i zoom in thanks for your help so far -- View this message in context: http://old.nabble.com/ginput%28%29-mouse--button-assignment-tp31735320p31735320.html Sent from the matplotlib - users mailing list archive at Nabble.com.
