I'm certain this is in an example somewhere but I can't seem to find it. If someone can just point me to the example I'll take it from there. Thank you! I have a line chart. I just want to add text or callout box that shows the last value in the line. Thank you very much, Chris -- View this message in context: http://old.nabble.com/Line-chart---want-to-show-value-of-last-data-point-tp26505250p26505250.html Sent from the matplotlib - users mailing list archive at Nabble.com. |

Use "text" or "annotate", eg http://matplotlib.sourceforge.net/examples/pylab_examples/annotation_demo.html http://matplotlib.sourceforge.net/examples/pylab_examples/annotation_demo2.html Let us know if you need any more help JDH |

This was exactly what I needed. I now have annotations all over the place. One last question. My graph is updating constantly and I need to move annotation around to highlite certain points as they appear. I can add new annotations easily enough and they stick to the place where I put them. As more data is added to the graph, the old annotations become irrelevant and I need to remove them. How do I delete the ones I don't need anymore from the graph? I could also just just modify the properties of the existing ones, both the text and location, if I knew how to get at them, so to speak. Can you point me the right way? -- View this message in context: http://old.nabble.com/Line-chart---want-to-show-value-of-last-data-point-tp26505250p26532286.html Sent from the matplotlib - users mailing list archive at Nabble.com. |
