Plot a line from [x1, y1] to [x2, y2]

See original GitHub issue

Hey, this library is great and super easy to use. Thanks for writing it!

I’m now trying to draw a line between two coordinates but can’t seem to get it working. Any recommendations how I can do this easily? Happy to send a PR if it comes to that.

I’ve tried a few things but none of them are satisfactory. Ideally, the interface would be similar to add_band(), it could be something like add_line(ax, [x1, y1], [x2, y2], width, color).

Here is what I’ve tried so far:

Added the code below to the example in the README but this only works if I comment out the calls to fplt.PandasDataSource and candlestick_ochl. If I don’t comment these lines, then the code below does not work.

line = fplt.pg.LineSegmentROI([[0,0], [1100, 200]], pen=(255,9,0), movable=False) line.setZValue(60) ax2.addItem(line)

Also tried fplt.addline and fplt.pg.LineROI but they show the same behavior as above.

How do I draw a line between two coordinates? Thanks!

Hi Naman,

Sorry for the late reply. I just added the feature you requested, fetch it by pip install -U finplot. I also included an example: https://github.com/highfestiva/finplot/blob/master/finplot/example-line.py. Good luck!

line = fplt.pg.LineSegmentROI([[0,0], [1100, 200]], pen=(255,9,0), movable=False) line.setZValue(60) ax2.addItem(line)
