At Thanks for look around my result. Above all, please understand my English skill..

There are 3 files in this repository

  • README.md
  • R script for making assignment plot
  • PNG image files which represent plots.

    • Here is Dataset. Electric power consumption [20Mb]

    The following descriptions of the 9 variables in the dataset are taken from the UCI web site:

    1. Date: Date in format dd/mm/yyyy
    2. Time: time in format hh:mm:ss
    3. Global_active_power: household global minute-averaged active power (in kilowatt)
    4. Global_reactive_power: household global minute-averaged reactive power (in kilowatt)
    5. Voltage: minute-averaged voltage (in volt)
    6. Global_intensity: household global minute-averaged current intensity (in ampere)
    7. Sub_metering_1: energy sub-metering No. 1 (in watt-hour of active energy). It corresponds to the kitchen, containing mainly a dishwasher, an oven and a microwave (hot plates are not electric but gas powered).
    8. Sub_metering_2: energy sub-metering No. 2 (in watt-hour of active energy). It corresponds to the laundry room, containing a washing-machine, a tumble-drier, a refrigerator and a light.
    9. Sub_metering_3: energy sub-metering No. 3 (in watt-hour of active energy). It corresponds to an electric water-heater and an air-conditioner.

    Summary

    1. Download Dataset
    2. Load data and extract data from 2007-2-1 to 2007-2-2
    3. Modify variables classes appropriate for making plots
    4. Make plots and save plots

    Problem

    In plot3 and plot4, legend in PNG file is cut off...please look at my PNG file. In window screen, there is no problem at legend, but when I save images, problem happens. I think problem appears when setting images for certain size.
