Gnuplot to matplotlib time series

Hi, I’m struggling to reproduce some Gnuplot plots:

kaihendry/covid19-sg/blob/master/gnuplot.ipynb

{
 "cells": [
  {
   "cell_type": "code",
   "execution_count": 37,
   "metadata": {},
   "outputs": [],
   "source": [
    "%gnuplot inline svg"
   ]
  },
  {
   "cell_type": "code",
   "execution_count": 38,
   "metadata": {},
   "outputs": [
    {
     "data": {
      "text/plain": [
       "\u001b[?1l\u001b>\u001b[?1h\u001b=\u001b[?1l\u001b>\u001b[?1h\u001b="

Into mathplotlib:

  {

    "import pandas as pd"
   ]
  },
  {
   "cell_type": "markdown",
   "metadata": {},
   "source": [
    "# John Hopkins csse_covid_19_daily_reports data inconsistent\n",
    "\n",
    "https://github.com/CSSEGISandData/COVID-19/blob/master/csse_covid_19_data/csse_covid_19_daily_reports/02-04-2020.csv\n",
    "\n",

How do I plot against Last_Update being on the X axis? Any tips what to read, because [links retracted since I’m limited to two URLs]

Thanks !

Would normal plot work

plt.plot("Last_Update", "Confirmed", data=sg)
plt.plot("Last_Update", "Deaths", data=sg)
plt.plot("Last_Update", "Active", data=sg)

Then just set needed properties as described here https://matplotlib.org/3.3.1/api/_as_gen/matplotlib.pyplot.plot.html

Ps. You can also use sg["Last_Update"] instead of str + data= structure

Thank you, I’ve since updated https://github.com/kaihendry/covid19-sg/blob/master/pandas.ipynb

Is it possible to produce plots where if you mouse over you can use the value for that x/y mouse position?

Thank you!

that is called hovering. Yes, with some interactive backends have possibility to use the hover option.
