+# LogarithmPlotter file format v1.0
+LogarithmPlotter files (with the extension .lpf, .lgg, .json), are json-encoded files.
+
+JSON Tree:
+
+    top level
+    ├─ type: <string> "logplotv1"
+    ├─ width: <number> width in pixels of the plot.
+    ├─ height: <number> height in pixels of the plot.
+    ├─ xzoom: <number> Number of pixels between each unit on the x axis.
+    ├─ yzoom: <number> Number of pixels between each unit on the y axis.
+    ├─ xmin: <number> Minimum x coordinate from which the plot should draw.
+    ├─ ymax: <number> Maximum y coordinate from which the plot should draw.
+    ├─ yaxisstep: <string> distance between each graduation in the y axis. String because it's an expression (e.g. 1/2, pi+1).
+    ├─ xaxisstep: <string> (only in non-logarithmic scale) Distance between each graduation in the x axis.
+    ├─ xaxislabel: <string> Label used for the x axis.
+    ├─ yaxislabel: <string> Label used for the y axis.
+    ├─ logscalex: <boolean> When true, the x axis is rendered with a logarithmic scale.
+    ├─ linewidth: <number> Weight of elements drawn on the plot (line width, dot's size...).
+    ├─ showxgrad: <boolean> When false, hides numbers from the x axis' graduation.
+    ├─ showygrad: <boolean> When false, hides numbers from the y axis' graduation.
+    ├─ textsize: <number> Base font size for the text drawn on the plot..
+    ├─ history: <list> Root items from history
+    │  ├─ 0: <history action list> stack of undo actions (from most ancient to most recent) 
+    │  │  └─ History action: [history action type, list of arguments for corresponding history action type]
+    │  └─ 1: <history action list> stack of redo actions (from most advanced to now)
+    │     └─ History action: [history action type, list of arguments for corresponding history action type]
+    └─ objects: <object dictionary> dictionary of actions with their property (from most advanced to now)
+       └─ key: object type, value: list of arguments for corresponding object type
