Import graph :

  • Find your document contains your graph chart or picture, select it and copy it to clipboard through CTRL-C; this is external work outside of QPlot.
  • Now go back to QPlot, switch to "Plier mode" under the menu "Plier". You'll see a blank page with two presetted axises x y right away with magnify glass toggled on by default.
  • If graph is present while switching to "Plier mode", it'll automatically pasted or you just need to paste it manually by pressing CTRL-V.

Setup axis :

  • The presetted axis won't meet with their destination automatically, their initial range are set as 0.0 to 1.0. So you need to adjust their postion and range manually
  • Select any axis(red line) by click, move it around by dragging the middle part of the line; resize the axis by dragging either end of the line. Match your axis with the axis on the pasted graph where you want it be. Use magnify glass for accurate match.
  • Tips: You don't have to match the axis starting from the origin of the graph. Just put it anywhere where readings are avariable for both ends of the axis.
  • Under the menu "Plier mode", click assign axis to set the range of axis, starting from x to y
  • Now, you can move your mouse around, and check if you get correct readings from the tracking panel below
  • Axis can be re-adjusted at any time, same with assigning axis range.
  • Tips: Always use magnify glass for confidence)





Extract data :

  • Under menu "Series", select "add point mode"
  • Click on the chart to add points (Tips: points can be dragged around so don't worry if you can't get it right the first time)
  • Points style can be adjusted by select "customize line series" under menu "Series"
  • Press CTRL-C any time to export series data to clipboard.
  • If you want to add another series, just select "add an empty line" under "Series", click series title to switch between active series.
