Project Description

Français Polski
You may have lost data of a chart, keeping only the chart. Or you may have a chart from a paper which does not give the data. By simply clicking on the picture, OOoDigitizer will calculate coordinates and give you (X,Y) data in your favorite spreadsheet. Just click on menu entry Tools > Add-on > OOoDigitizer, and follow this 4 steps:

  • Step 1. Load your picture of the chart (from image file 1. (PNG, JPG, GIF), or PDF file, or clipboard). You may also:
    • Resize
    • Crop
    • Rotate your picture
  • Step 2. Define axis scales:
    • XY or polar coordinates
    • linear or log scale
    • time or date for X axis
  • Step 3. Create a series, then click on the points of the chart. You may choose:
    • color and shape of the pointer
    • to display or not other series, axis, lines between points, the picture
    • size of the points and the lines
    • auto-digitizing via interpolation
  • Step 4. Save in your spreadsheet or CSV file:
    • one series per sheet/file
    • all series in the same sheet/file

Français : Numérisation de diagramme XY

Description du projet

Il vous est peut-être arrivé de perdre les données pour construire un graphe et de n'avoir plus qu'une sortie papier, ou de vouloir reconstruire un graphe à partir d'un document PDF. Par simples clics sur l'image, OOoDigitizer va calculer les coordonnées et vous finir les valeurs des données (X,Y) dans votre tableur préféré.Sélectionnez l'entrée du menu Outils > Add-on > OOoDigitizer et suivez ces quatre étapes :

  • Étape 1 : chargez l'image du diagramme soit à partir d'un fichier image (PNG, JPG, GIF) ou d'un fichier PDF, soit à partir du presse-papier. Vous pouvez de plus :
    • redimensionner
    • rogner
    • faire une rotation à l'image
  • Étape 2 : définissez les échelles des axes :
    • coordonnées cartésiennes XY ou polaires
    • échelles linéaires ou logarithmiques
    • échelle des absisses en heure ou en date
  • Étape 3 : créez une série, puis cliquez sur les points du diagramme. Vous pouvez choisir :
    • la couleur et la forme du pointeur
    • d'afficher ou non les autres séries, les axes, des lignes entre les points, l'image
    • la taille des points et des lignes
    • la détermination automatique de points supplémentaires par interpolation
  • Étape 4 : enregistrez dans votre classeur un fichier CSV :
    • une série par feuille/fichier
    • toutes les séries dans la même feuille/fichier

Opis projektu

Jeżeli posiadasz wykres lecz nie masz dostępu do danych z których on powstał wtedy rozszerzenie OOoDigitizer pozwoli Ci w prosty sposób te dane odzyskać. Program uruchamia się z menu menu: Narzędzia > Dodatki > OOoDigitizer. Odzyskiwanie danych przebiega w czterech krokach:

  1. Wczytanie rysunku wykresu (PNG, JPG, GIF lub plik PDF). Dostępne opcje edycji rysunku:
    • skalowanie
    • przycinanie
    • obracanie
  2. Zdefiniowanie osi wykresu:
    • współrzędne XY lub polarne
    • skala liniowa lub logarytmiczna
    • czas lub data na osi X
  3. Odzyskanie wybranych serii danych. Dostępne opcje:
    • kolor i kształt wskaźnika myszy
    • wyświetlanie: poszczególnych serii, osi, linii pomiędzy punktami, rysunku
    • rozmiar punktów, grubość linii
    • auto-digitizacja przy użyciu interpolacji
  4. Zapisanie odzyskanych danych do arkusza Calc lub do pliku CSV:
    • jedna seria na arkusz/plik
    • wszystkie serie w tym samym arkuszu/pliki
