hi everybody,

i'm new with pd and most of the objects. i have a question to which i can't find an answer by myself and i hope that some experienced user can save me some more hours.

is it possible to click on the position in the graph / plot of a recorded sample and thus get the x-position / index?

i want to realize a small patch in which i can determine the different segments of an array / sample and i assume that there is a way to show the output because it is very easy to change the graph manually.

tanks in advance

what i do, is put a slider under the graph, and size the slider to the same length as the graph.

..and then you can also put a canvas behind the graph to line things up nicely..see attached patch

tanks again,

with your help i'm almost finished with my sampler. one last question about the graph on parent function:
my graph has the X-size of 6000 but the plot only shows the signal up to the size of 2000 (draw as points). when i choose another representation (for ex. polygon) it becomes even less. is there a limit for the different figures?

sorry, not sure what you mean.

are you trying to draw a graph with a width of 6000 pixels?

exactly, i'm trying to plot a wav-file, or in the case of pure data an array, which for example has 882000 samples. to make the visualisation very detailed, i want to scale it in a very large width - for ex. 6000 px, but pd cuts the signal at the length of 2000 px. the visible array "container" is really 6000 px long and according to what i see of the signal it is correctly scaled with the problem that it's only visible till 2000 px. hope you can follow me

EDIT: attached a screenshot

hmm, in that case my guess would be that graphs in pd are hardwired to 2000px maximum to avoid overloads.

so, i can guess what you are doing is scrolling left and right to view your soundfile. a more conservative option may be to keep your original soundfile in an undrawn table (ie, make a
